-## 2021.5 - May 2023
-
-- Added new [NOWEB engine]({{< relref "/docs/how-to/engines" >}}). **NOWEB** engine does not require a browser to work
-  with
-  WhatsApp Web, it does so directly using a WebSocket.
-  - Less CPU and RAM usage!
-  - Send Locations API works!
-  - Send Link Preview API works!
-  - ⚠ Read the article before using it [How to avoid blocking ->]({{< relref "/docs/help/how-to-avoid-blocking" >}}).
-
-## 2021.4 - March 2023
-
-- Add [Groups API]({{< relref "/docs/how-to/groups" >}})
-- Use Chromium by default instead of Chrome
-
-## 2021.1 - January 2023
-
-- Added  [Contacts API]({{< relref "/docs/how-to/contacts" >}})
-  - Get all contacts
-  - Get a contact
-  - Get contact "about" (status)
-  - Get contact profile picture
-  - Check number exists (is registered in WhatsApp) - works even if the number is not in the contact list
-  - Block and unblock contact
-
-## 2022.12 - December 2023
-
-- Added `GET /messages/` endpoint to get chat messages [#31](https://github.com/devlikeapro/whatsapp-http-api/issues/31)
-
-### Security ![](/images/versions/plus.png)
-
-- Added `WHATSAPP_SWAGGER_USERNAME` and `WHATSAPP_SWAGGER_PASSWORD` to hide and protect swagger panel.
-
-## 2022.11
-
-**Please test changes in test environment before update production!!**
-
-### Engine ![](/images/versions/core.png)
-
-1. WAHA has changed its underlying engine from Venom to Whatsapp Web.JS. It might change the response and webhook's
-   payloads.
-2. Optimize CPU and memory consumption.
-
-### Requests ![](/images/versions/core.png)
-
-- For all `/api/session/` requests use `name` field instead of `sessionName`.
-- For all "chatting" requests use `session` field instead of `sessionName`.
-
-### Sessions ![](/images/versions/plus.png)
-
-Now you don't have to scan QR code each time you run WAHA, WAHA saves it for you! Available only in Plus version.
-
-### Authentication ![](/images/versions/plus.png)
-
-Now you can authenticate all requests for WAHA - use `WHATSAPP_API_KEY=secret` environment variable to set "secret key".
-
-If `WHATSAPP_API_KEY` is set - requests must have `X-Api-Key` header with `secret` value, where `secret` - any random
-secret key.
-
-### Webhooks ![](/images/versions/core.png)
-
-#### Configuration
-
-Instead of setting each webhook via environment variables - we use two environments variables:
-
-- `WHATSAPP_HOOK_URL` - to set a URL
-- `WHATSAPP_HOOK_EVENTS` - to set events that are sent to the URL
-
-| Previous                                                                                                             | Current                                                                                            |

-
-#### Payload
-
-The data for webhooks are wrapped inside a new `WAWebhook` object with `event` and `payload` fields to help you identify
-which handler you should call based on `event`.
-
-```json
-{
-  "event": "message.any",

-  must be separated by a comma, without spaces: `audio,image/png,image/gif`. In order to choose type use prefix (
-  like `audio,image`).
-- `WHATSAPP_FILES_LIFETIME`- to keep free space files will be removed after this time (default: `180`, in seconds)
-- `WHATSAPP_FILES_FOLDER` - folder where will be stored files from chats (images, voice messages) (
-  default: `/tmp/whatsapp-files`)
+### Sessions
+- `WHATSAPP_RESTART_ALL_SESSIONS=True`: Set this variable to `True` to start all **STOPPED** sessions after container
+  restarts. By default, this variable is set to `False`.
+  - Please note that this will start all **STOPPED** sessions, not just the sessions that were working before the restart. You can maintain the session list by
+    using `POST /api/session/stop` with the `logout: True` parameter or by calling `POST /api/session/logout` to remove
+    **STOPPED** sessions. You can see all sessions, including **STOPPED** sessions, in the `GET /api/sessions/all=True`
+    response.
+- `WHATSAPP_START_SESSION=session1,session2`: This variable can be used to start sessions with the specified names right
+  after launching the API. Separate session names with a comma.
+
+### Swagger
+- `WHATSAPP_SWAGGER_CONFIG_ADVANCED=true` - enables advanced configuration options for Swagger documentation - you can customize host, port and base URL for the requests.
+  Disabled by default.
+
+### Proxy
+#### Global proxy configuration
+If you need to use a proxy, you can set the following environment variables:
+
+- `WHATSAPP_PROXY_SERVER=localhost:3128`: Use this variable to set the proxy server in the format `host:port`, without http or https.
+- `WHATSAPP_PROXY_SERVER_USERNAME=username` and `WHATSAPP_PROXY_SERVER_PASSWORD=password`: Use these variables to set up credentials for the proxy.
+- `WHATSAPP_PROXY_SERVER_LIST=host1.example.com:3138,host2.example.com:3138`: Use this variable to set a comma-separated list of addresses to use, using a round-robin algorithm to choose the server for the session.
+- `WHATSAPP_PROXY_SERVER_INDEX_PREFIX=proxy-`: Use this variable to parse the session name for the prefix and find the appropriate session.
+  For example, if you have set `WHATSAPP_PROXY_SERVER_LIST=host-first:80,host-second:80,host-third:80` and `WHATSAPP_PROXY_SERVER_INDEX_PREFIX=proxy-` and you run `proxy-3` session, the `host-third:80` proxy will be chosen for that session.
+  This is a way to select a proxy from while you start session.
+
+#### Session proxy configuration
+You can configure proxy when you start session by setting `config.proxy` fields.
+Read more about it on [**Session page** ->]({{< relref "/docs/how-to/sessions#configure-proxy" >}}).
+
+Keep in mind that session's proxy configuration takes precedence over proxy configuration set by environment variables!
+
+
+### Security ![](/images/versions/plus.png)
+- `WHATSAPP_API_KEY=mysecret`: If you set this variable, you must include the `X-Api-Key: mysecret` header in all
+  requests to the API. This will protect the API with a secret code.
+- `WHATSAPP_SWAGGER_USERNAME=admin` and `WHATSAPP_SWAGGER_PASSWORD=admin`: These variables can be used to protect the
+  Swagger panel with `admin / admin` credentials. This does not affect API access.
+
+
+### Files ![](/images/versions/plus.png)
+
+The following environment variables can be used to configure the file storage options for the WAHA:
+
+- `WHATSAPP_FILES_MIMETYPES`: This variable can be used to download only specific mimetypes from messages. By default,
+  all files are downloaded. The mimetypes must be separated by a comma, without spaces. For
+  example: `audio,image/png,image/gif`. To choose a specific type, use a prefix (like `audio,image`).
+- `WHATSAPP_FILES_LIFETIME`: This variable can be used to set the time (in seconds) after which files will be removed to
+  free up space. The default value is `180`.
+- `WHATSAPP_FILES_FOLDER`: This variable can be used to set the folder where files from chats (images, voice messages)
+  will be stored. The default value is `/tmp/whatsapp-files`.
+
+## Examples
+
+#### Debug Mode
+
+To enable debug mode, set the `DEBUG` environment variable to any value:
+
+```
+DEBUG=1
+```
+
+#### Protecting the API with a Secret Code
+
+To protect the API with a secret code, set the `WHATSAPP_API_KEY` environment variable to your secret code:
+
+```
+WHATSAPP_API_KEY=mysecret
+```
+
+You must include the `X-Api-Key: mysecret` header in all requests to the API.
+
+#### Starting Sessions Automatically
+
+To start sessions automatically when the API is launched, set the `WHATSAPP_START_SESSION` environment variable to a
+comma-separated list of session names:
+
+```
+WHATSAPP_START_SESSION=session1,session2
+```
+
+#### Restarting All Sessions
+
+To start all **STOPPED** sessions after container restarts, set the `WHATSAPP_RESTART_ALL_SESSIONS` environment variable
+to `True`:
+
+```
+WHATSAPP_RESTART_ALL_SESSIONS=True
+```
+
+#### Protecting the Swagger Panel
+
+To protect the Swagger panel with `admin / admin` credentials, set the `WHATSAPP_SWAGGER_USERNAME`
+and `WHATSAPP_SWAGGER_PASSWORD` environment variables:
+
+```
+WHATSAPP_SWAGGER_USERNAME=admin
+WHATSAPP_SWAGGER_PASSWORD=admin
+```
+
+
+#### Downloading Specific Mimetypes
+
+To download only specific mimetypes from messages, set the `WHATSAPP_FILES_MIMETYPES` environment variable to a
+comma-separated list of mimetypes:
+
+```
+WHATSAPP_FILES_MIMETYPES=audio,image/png,image/gif
+```
+
+#### Setting the File Lifetime
+
+To set the time (in seconds) after which files will be removed to free up space, set the `WHATSAPP_FILES_LIFETIME`
+environment variable:
+
+```
+WHATSAPP_FILES_LIFETIME=300
+```
+
+#### Setting the File Storage Folder
+
+To set the folder where files from chats (images, voice messages) will be stored, set the `WHATSAPP_FILES_FOLDER`
+environment variable:
+
+```
+WHATSAPP_FILES_FOLDER=/home/user/whatsapp-files
+```

+It includes tips on how to avoid running long command lines, how to view logs, and other helpful advice.
+
+## How to Use Docker Compose
+
+Docker Compose is a tool that allows you to define and run multi-container Docker applications. It simplifies the
+process of managing multiple containers and their dependencies. In this topic, we will walk you through how to use
+Docker Compose with the WhatsApp HTTP API.
+
+### Prerequisites
+
+Before you start, you need to have Docker and Docker Compose installed on your machine. You can download Docker from the
+official website [here](https://www.docker.com/products/docker-desktop). Docker Compose is included with Docker Desktop
+for Windows and macOS, but for Linux, you need to install it separately. You can find the installation
+instructions [here](https://docs.docker.com/compose/install/).
+
+### Getting Started
+
+To get started, you need to clone the [docker-compose.yaml](https://github.com/devlikeapro/whatsapp-http-api/blob/core/docker-compose.yaml) file to your local machine.
+Open your terminal and run the following command:
+
+```
+wget https://raw.githubusercontent.com/devlikeapro/whatsapp-http-api/core/docker-compose.yaml
+```
+
+### Running the WhatsApp HTTP API Service
+
+To start the `whatsapp-http-api` service, run the following command:
+
+```
+docker-compose up -d whatsapp-http-api
+```
+
+This will start the container in detached mode and map port 3000 to 3000 on the host machine.
+
+To stop the service, run the command:
+
+```
+docker-compose down
+```
+
+This will stop and remove the container.
+
+To restart the service, run the command:
+
+```
+docker-compose restart whtasapp-http-api
+```
+
+This will restart the container.
+
+### Viewing the Logs
+
+To view the logs for the `whatsapp-http-api` service, run the command:
+
+```
+docker-compose logs -f whatsapp-http-api
+```
+
+This will show the logs in real-time. To view the logs for the `whatsapp-http-api-plus` service,
+replace `whatsapp-http-api` with `whatsapp-http-api-plus`.
+
+To view the logs for a specific period, run the command:
+
+```
+docker-compose logs --since <time>
+```
+
+Replace `<time>` with the time period you want to view the logs for. For example, `docker-compose logs --since 1h` will
+show the logs for the past hour.
+
+### Using the WhatsApp HTTP API Services
+
+There are two services provided in the `docker-compose.yml` file - `whatsapp-http-api` and `whatsapp-http-api-plus`.
+It is important to note that these services must not be run at the same time.
+By default, the `whatsapp-http-api` service will be used.
+
+To use the `whatsapp-http-api-plus` service, you need to specify it in the command.

+You can get presence information (online, offline with last seen, typing status) for a contact if they share their
+presence information.
+
+Possible presence statuses that you can set or get for chats:
+- `online`
+- `offline`
+- `typing`
+- `recording`
+- `paused` resets the chat presence after you were `typing`
+
+
+## Endpoints
+
+### Set presence
+You can set your global or chat-related presence with `POST /api/{session}/presence` endpoint
+
+Start typing to a chat (you can use `POST /startTyping` instead)
+```json
+{
+  "chatId": "111111111@c.us",
+  "presence": "typing"
+}
+```
+
+Clear "typing" state (you can use `POST /stopTyping` instead)
+```json
+{
+  "chatId": "111111111@c.us",
+  "presence": "paused"
+}
+```
+
+Set global "online", all contacts will see it
+```json
+{
+  "presence": "online"
+}
+```
+
+💡 In the multi-device version of WhatsApp - if a desktop client is active, WhatsApp doesn't send push notifications
+to the device.
+If you would like to receive said notifications - you need to mark a session's presence as `offline`.
+
+```json
+{
+  "presence": "offline"
+}
+```
+
+### Get all chats presence

+{{< alert icon="👉" text="Get presence endpoints and webhook is available only in **NOWEB** engine." />}}
+[Read more about engines to choose right for you ->]({{< relref "/docs/how-to/engines" >}})
+
+Here's few notes about fields:
+
+- `chatId` - either contact id (`213213213@c.us`) or group chat id (`1111111111111@g.us`).
+- `lastSeen` - contains Unix timestamps indicating when a participant was last online
+- `lastKnownPresence` - contains the last known presence status, which can be
+  `offline`, `online`, `typing`, `recording`, or `paused`
+
+
+You can get all presence information available for a session by calling `GET /api/{session}/presence/`.
+It returns both groups' and personal chats' presence information.
+
+```json
+[
+  {
+    "id": "2132132130@c.us",

+      }
+    ]
+  }
+]
+```
+
+### Get chat presence
+
+To get presence information for a single chat - call `GET /api/{session}/presence/{chatId}`.
+For a group, you'll get participants' statuses.
+
+```json
+{
+  "id": "2132132130@c.us",
+  "presences": [
+    {
+      "participant": "2132132130@c.us",
+      "lastKnownPresence": "online",
+      "lastSeen": null
+    }
+  ]
+}
+```
+
+### Subscribe to presence
+
+You can subscribe to presence information by calling `POST /api/{session}/presence/{chatId}/subscribe` request
+(no body required).
+You can get later presence information for the chat with above `GET` endpoints or by listening to `presence.update`
+webhook.
+
+## Webhook
+
+You can subscribe to `presence.update` webhook event to get the most recent presence information.
+

-The project uses [Webhooks](https://en.wikipedia.org/wiki/Webhook) to send the messages and events from WhatsApp to your
-application.
+If you haven't yet - please follow the steps from [**Quick Start →**]({{< relref "/docs/overview/quick-start" >}}).
 
-Webhooks are a way for two different applications to communicate with each other in real-time.
-When a certain event happens in one application, it sends a message to another application through a webhook URL.
-The receiving application can then take action based on the information received.
+## Webhooks
 
-To receive incoming messages with webhooks,
-you first need to set up a webhook URL in your application and pass it to `WHATSAPP_HOOK_URL` environment variable.
-This URL is where WhatsApp will send incoming messages and other events -
-define which events you want to receive with `WHATSAPP_HOOK_EVENTS` environment variable.
-
-## Webhooks ![](/images/versions/core.png)
-
-You can configure where you want to receive events in environment variables:
-
-- `WHATSAPP_HOOK_URL=https://httpbin.org/post`  - to set up a URL for the webhook
-- `WHATSAPP_HOOK_EVENTS=message,message.any,state.change,group.join,group.leave` - specify events. DO NOT specify all of
-  them, it's too heavy payload, choose the right for you.
-  - `WHATSAPP_HOOK_EVENTS=*` - subscribe to all events. It's not recommended for production, but it's fine for
-  development.
-
-On the URL that you set via `WHATSAPP_HOOK_URL` you receive JSON-data with following format:
+You must use [Webhooks]({{< relref "/docs/how-to/webhooks" >}}) to receive messages from WhatsApp to your application.
 
+Start a new session with configured `message` event in webhooks - call `POST /api/sessions/start` with the payload:

+You can configure proxy for a session by setting `config.proxy` fields:
+- `server` - proxy server address, without `http://` or `https://` prefixes
+- `username` and `password` - set this if the proxy requires authentication
+
+
+**No authentication**

+## Advanced sessions ![](/images/versions/plus.png)
+
+With [WAHA Plus version]({{< relref "plus-version" >}}) you can save session state to avoid scanning QR code everytime,
+configure autostart options so when the docker container restarts - it restores all previously run sessions!
+
+### Session persistent
+
+#### File storage
+If you want to save your session and do not scan QR code everytime when you launch WAHA - connect a local file storage
+to the container. WAHA stores authentication information in the directory and reuses it after restart.
+
+[Attach volume](https://docs.docker.com/storage/volumes/) part to the command:
+
+```bash
+-v `pwd`/.sessions:/app/.sessions
+```
+
+The full command would be:
+
+```bash
+docker run --rm -d -v `pwd`/.sessions:/app/.sessions -p 3000:3000/tcp --name whatsapp-http-api devlikeapro/whatsapp-http-api-plus
+```
+
+#### Remote storage ![](/images/versions/soon.png)
+
+If you're interested in using some "remote" storage (like Redis or other Databases) to save sessions - please create an
+issue on GitHub.
+
+For instances, it may be useful if you run WAHA in a cluster of servers and do not have shared file storage
+
+### Autostart
+If you don't want to call `POST /api/sessions/start` for every session each time when the container restart -
+you can use set of these environment variables to start sessions for you:
+
+- `WHATSAPP_RESTART_ALL_SESSIONS=True`: Set this variable to `True` to start all **STOPPED** sessions after container
+  restarts. By default, this variable is set to `False`.
+  - Please note that this will start all **STOPPED** sessions, not just the sessions that were working before the restart. You can maintain the session list by
+    using `POST /api/session/stop` with the `logout: True` parameter or by calling `POST /api/session/logout` to remove
+    **STOPPED** sessions. You can see all sessions, including **STOPPED** sessions, in the `GET /api/sessions/all=True`
+    response.
+- `WHATSAPP_START_SESSION=session1,session2`: This variable can be used to start sessions with the specified names right
+  after launching the API. Separate session names with a comma.
+
+
+### Multiple sessions
+
+If you want to save server's CPU and Memory - run multiple sessions inside one docker container!
+[Plus version]({{< relref "plus-version" >}}) supports multiple sessions in one container.

+
+The project uses [Webhooks](https://en.wikipedia.org/wiki/Webhook) to send the messages and events from WhatsApp to your
+application.
+
+Webhooks are a way for two different applications to communicate with each other in real-time.
+When a certain event happens in one application, it sends a message to another application through a webhook URL.
+The receiving application can then take action based on the information received.
+
+## Setup webhooks
+### Session webhooks
+You can define webhooks configuration per session when you start it with `POST /api/sessions/start` request data.
+
+Here's a simple example:
+```json
+{
+  "name": "default",
+  "config": {
+    "webhooks": [
+      {
+        "url": "https://httpbin.org/post",
+        "events": [
+          "message"
+        ]
+      }
+    ]
+  }
+}
+
+```
+
+Here's available configuration options for webhooks
+```json
+{
+  "name": "default",
+  "config": {
+    "webhooks": [
+      {
+        "url": "https://httpbin.org/post",
+        "events": [
+          "message"
+        ],
+        "hmac": {
+          "key": "your-secret-key"
+        },
+        "retries": {
+          "delaySeconds": 2,
+          "attempts": 15
+        },
+        "customHeaders": [
+          {
+            "name": "X-My-Custom-Header",
+            "value": "Value"
+          }
+        ]
+      }
+    ]
+  }
+}
+```
+
+### Global webhooks
+There's a way how you can configure webhooks for ALL sessions - by settings these environment variables:
+
+- `WHATSAPP_HOOK_URL=https://httpbin.org/post`  - to set up a URL for the webhook
+- `WHATSAPP_HOOK_EVENTS=message,message.any,state.change` - specify events. Do not specify all of
+  them, it's too heavy payload, choose the right for you.
+- `WHATSAPP_HOOK_EVENTS=*` - subscribe to all events. It's not recommended for production, but it's fine for
+development.
+
+That webhook configuration **does not appear** in `session.config` field in `GET /api/sessions/` request.
+
+## Webhook payload
+
+On the URL that you set you'll receive **HTTP POST** request with a JSON string with following format:
+
+```json
+{
+  "event": "message",
+  "session": "default",
+  "engine": "WEBJS",
+  "payload": {
+    ...
+  }
+}
+```
+
+Where `event` value helps you identify the incoming event with `payload` for that events.
+
+Below the list of all events that WhatsApp HTTP API sends to your.
+
+{{< alert icon="👉" text="If you want to look at a webhook body - use the url https://httpbin.org/post" />}}
+
+Run the bellow command and see look at the logs - it prints body request for all events that happen in your WhatsApp!
+
+```bash
+docker run -it -e "WHATSAPP_HOOK_EVENTS=*" -e WHATSAPP_HOOK_URL=https://httpbin.org/post -p 3000:3000 devlikeapro/whatsapp-http-api
+```
+
+

+
+### message.any
+
+Fired on all message creations, including your own. The payload is the same as for [message](#message) event.
+

+
+It's an internal engine's state, not **session** `status`.

+  "payload": {
+    ...
+  }
+}
+```
+
+### presence.update
+
+- `payload.id` indicates the chat - either direct chat with a contact or a group chat.
+- `payload.id.[].participant` - certain participant presence status. For a direct chat there's only one participant.
+
+```json
+{
+    "event": "presence.update",
+    "session": "default",
+    "engine": "NOWEB",
+    "payload": {
+        "id": "111111111111111111@g.us",
+        "presences": [
+            {
+                "participant": "11111111111@c.us",
+                "lastKnownPresence": "typing",
+                "lastSeen": null
+            }
+        ]
+    }
+}
+```
+
+## Webhooks Advanced ![](/images/versions/plus.png)
+### HMAC authentication
+
+You can authenticate webhook sender by using [HMAC Authentication](https://www.okta.com/identity-101/hmac/).
+
+1. Define you secret key in `config.hmac.key` field when you start session with `POST /api/sessions/start`:
+
+```json
+{
+  "name": "default",
+  "config": {
+    "webhooks": [
+      {
+        "url": "https://httpbin.org/post",
+        "events": [
+          "message"
+        ],
+        "hmac": {
+          "key": "your-secret-key"
+        }
+      }
+    ]
+  }
+}
+```
+
+2. After that you'll receive all webhooks payload with two additional headers:
+- `X-Webhook-Hmac` - message authentication code for the raw **body** in HTTP POST request that send to your endpoint.
+- `X-Webhook-Hmac-Algorithm` - `sha512` - algorithm that have been used to create `X-Webhook-Hmac` value.
+
+3. Implement the authentication algorithm by hashing body and using secret key and then verifying it with `X-Webhook-Hmac`
+value. Please [check your implementation here ->](https://www.devglan.com/online-tools/hmac-sha256-online)
+
+Here's example for
+```
+# Full body
+{"event":"message","session":"default","engine":"WEBJS"}
+# Secret key
+my-secret-key
+# X-Webhook-Hmac-Algorithm
+sha512
+# X-Webhook-Hmac
+208f8a55dde9e05519e898b10b89bf0d0b3b0fdf11fdbf09b6b90476301b98d8097c462b2b17a6ce93b6b47a136cf2e78a33a63f6752c2c1631777076153fa89
+```
+
+
+### Retries
+**WAHA** retries to reach your webhook URL **15 times** with **2 seconds delay** between attempts by default in
+[Plus Version →]({{< relref "plus-version" >}})
+
+You can configure those parameters by settings `config.retries` structure when `POST /api/sessions/start`:
+
+```json
+{
+  "name": "default",
+  "config": {
+    "webhooks": [
+      {
+        "url": "https://httpbin.org/post",
+        "events": [
+          "message"
+        ],
+        "retries": {
+          "delaySeconds": 2,
+          "attempts": 15
+        }
+      }
+    ]
+  }
+}
+
+```
+
+### Custom Headers
+You can send any customer headers by defining `config.webhooks.customHeaders` fields this way:
+```json
+{
+  "name": "default",
+  "config": {
+    "webhooks": [
+      {
+        "url": "https://httpbin.org/post",
+        "events": [
+          "message"
+        ],
+        "customHeaders": [
+          {
+            "name": "X-My-Custom-Header",
+            "value": "Value"
+          }
+        ]
+      }
+    ]
+  }
+}
+```
+
+## Examples
+Here's few examples of how to handle webhook in different languages:
+1. [Python guide]({{< relref "/docs/examples/python" >}})
+
+**Do you use another language?**
+
+Please create a short guide how to handle webhook and send message after you finish your setup!
+You can create a pull request with your favorite language in the
+[GitHub, in examples folder ->](https://github.com/devlikeapro/whatsapp-http-api/tree/core/examples).

+## 2023.8
+August 2023
+- Added [chats endpoints](https://waha.devlike.pro/docs/how-to/chats)
+  - Get all chats - `GET /api/{session/chats`
+  - Delete chat - `DELETE /api/{session/chats/{chatId}`
+  - Get messages from chat - `GET /api/{session/chats/{chatId}/messages?limit=1000?downloadMedia=true`
+  - Clear messages in the chat `DELETE /api/{session/chats/{chatId}/messages`
+- Added `downloadMedia` flag to speed up `GET /api/messages` and `GET /api/{session/chats/{chatId}/messages` performance.
+- Added [set presence endpoint](https://waha.devlike.pro/docs/how-to/presence)!
+  - With `online` presence you can show your status as online [#121](https://github.com/devlikeapro/whatsapp-http-api/issues/121)
+  - With `offline` presence you can get notifications for your device [#28](https://github.com/devlikeapro/whatsapp-http-api/issues/28)
+
+## 2023.7
+July 2023
+- Now session can have their own [Webhooks](https://waha.devlike.pro/docs/how-to/webhooks) -
+   you can define webhook configuration when you start a session with `POST /api/session/start`!
+  - Add HMAC authentication for webhooks
+  - Configure retries
+  - Add you custom headers
+- Added [proxy configuration](https://waha.devlike.pro/docs/how-to/config/#proxy) with supporting proxy authentication.

+  a contact by calling endpoints or receiving a webhook event!
+- Now you can mention contact in groups by settings `mentions` field in `POST /api/sendText`
+  [read more about it in Send Messages ->]({{< relref "/docs/how-to/send-messages" >}})
+
+## 2023.6
+June 2023
+
+Improvements on session management, restarting sessions and more:
+
+- Added `WHATSAPP_RESTART_ALL_SESSIONS=True`: Set this variable to `True` to start all **STOPPED** sessions after
+  container restarts. By default, this variable is set to `False`.
+  - Please note that this will start all **STOPPED** sessions, not just the sessions that were working before the
+    restart. You can maintain the session list by
+    using `POST /api/session/stop` with the `logout: True` parameter or by calling `POST /api/session/logout` to remove
+    **STOPPED** sessions. You can see all sessions, including **STOPPED** sessions, in the `GET /api/sessions/all=True`
+    response.
+- `WHATSAPP_START_SESSION` now support more than one session! Separate session names by command, and it'll start them
+  ALWAYS after container restart `WHATSAPP_START_SESSION=session1,session2`
+- `WHATSAPP_SWAGGER_CONFIG_ADVANCED=true` enables advanced configuration options for Swagger documentation - you can customize host, port and base URL for the requests.
+  Disabled by default.
+- Added `?all=true` parameter to `GET /api/session?all=True` endpoint - it'll show you ALL session, included **STOPPED
+  **, so you can know which one will be restarted if you set `WHATSAPP_RESTART_ALL_SESSIONS=True` environment variable.
+- Added `POST /api/sessions/logout` that allow you to logout from session - remove saved credentials.
+- Added `logout` boolean parameter to `POST /api/sessions/stop` request that allow you to stop the session AND logout at
+  the same time.
+- Added [How to deploy page ->]({{< relref "/docs/how-to/deploy" >}}) with
+  [docker-compose.yaml](https://github.com/devlikeapro/whatsapp-http-api/blob/core/docker-compose.yaml) example
+- Added `engine` field in webhook payload
+
+```json
+{
+  "event": "message",
+  "session": "default",
+  "engine": "WEBJS",
+  "payload": {}
+}
+```
+
+## 2023.5
+May 2023
+
+- Added new [NOWEB engine]({{< relref "/docs/how-to/engines" >}}). **NOWEB** engine does not require a browser to work
+  with
+  WhatsApp Web, it does so directly using a WebSocket.
+  - Less CPU and RAM usage!
+  - Send Locations API works!
+  - Send Link Preview API works!
+  - ⚠ Read the article before using it [How to avoid blocking ->]({{< relref "/docs/overview/how-to-avoid-blocking" >}}).
+
+## 2023.4
+March 2023
+
+- Add [Groups API]({{< relref "/docs/how-to/groups" >}})
+- Use Chromium by default instead of Chrome
+
+## 2023.1
+January 2023
+
+- Added  [Contacts API]({{< relref "/docs/how-to/contacts" >}})
+  - Get all contacts
+  - Get a contact
+  - Get contact "about" (status)
+  - Get contact profile picture
+  - Check number exists (is registered in WhatsApp) - works even if the number is not in the contact list
+  - Block and unblock contact
+
+## 2022.12
+December 2023
+
+- Added `GET /messages/` endpoint to get chat messages [#31](https://github.com/devlikeapro/whatsapp-http-api/issues/31)
+
+### Security ![](/images/versions/plus.png)
+
+- Added `WHATSAPP_SWAGGER_USERNAME` and `WHATSAPP_SWAGGER_PASSWORD` to hide and protect swagger panel.
+
+## 2022.11
+
+**Please test changes in test environment before update production!!**
+
+### Engine ![](/images/versions/core.png)
+
+1. WAHA has changed its underlying engine from Venom to Whatsapp Web.JS. It might change the response and webhook's
+   payloads.
+2. Optimize CPU and memory consumption.
+
+### Requests ![](/images/versions/core.png)
+
+- For all `/api/session/` requests use `name` field instead of `sessionName`.
+- For all "chatting" requests use `session` field instead of `sessionName`.
+
+### Sessions ![](/images/versions/plus.png)
+
+Now you don't have to scan QR code each time you run WAHA, WAHA saves it for you! Available only in Plus version.
+
+### Authentication ![](/images/versions/plus.png)
+
+Now you can authenticate all requests for WAHA - use `WHATSAPP_API_KEY=secret` environment variable to set "secret key".
+
+If `WHATSAPP_API_KEY` is set - requests must have `X-Api-Key` header with `secret` value, where `secret` - any random
+secret key.
+
+### Webhooks ![](/images/versions/core.png)
+
+#### Configuration
+
+Instead of setting each webhook via environment variables - we use two environments variables:
+
+- `WHATSAPP_HOOK_URL` - to set a URL
