6ecf98671a docs(platform): add Platform Webhooks guide and event catalog (#51098)
## Problem

Platform Webhooks (org- and project-level event notifications over the
Management API) has no public documentation. CTRL-1017 asks for a docs
page plus a specification of the available event types, so partners can
integrate without reading the OpenAPI spec or asking engineering
directly.

Closes CTRL-1017.

## Solution

**New guide covering the Management API path, plus an event catalog.**

Adds `apps/docs/content/guides/platform/webhooks.mdx`: concepts and
scoping, creating an endpoint, Standard Webhooks signature verification
and secret rotation, test events, and delivery/retry/ordering behavior.

Adds `apps/docs/content/guides/platform/webhooks/events.mdx`: the events
reference.

- Full payload documentation for the 8 project-lifecycle event types,
and a name-and-trigger table for the 12 branch, member, and billing
types whose payload fields aren't documented.
- Documents `*` for subscribing to every event.
- Access framing states the criterion: available to organizations on an
early access allowlist, with the `403` / `access_disabled` response for
everyone else.
- Nav entry under Platform > Project & Account Management, after
Personal Access Tokens, gated by `fullPlatformEnabled`.

**The page deliberately omits the dashboard UI.** See the first row of
the table below.

## Needs review before merge

| **The Studio webhooks UI is not wired to the API, so this page
documents the Management API only** | `PlatformWebhooksPage.tsx:29`
imports `PLATFORM_WEBHOOKS_MOCK_DATA`; `PlatformWebhooks.store.ts` has
no async or network code and hardcodes `createdBy:
'mock-user@supabase.io'`; nothing in `apps/studio` references
`webhooks/endpoints` or `webhooks/deliveries`, even though
`api-types/types/api-v2.d.ts` carries those paths 24 times. #43276
(DEPR-340) described it as "UI-only (with mock data)", and the
`DEPR-340-backend-integration-tracker.md` it pointed to is no longer in
the tree. A dashboard section can be added once the UI calls the API. |
| Possible reference slug collision | Project- and org-scoped operations
share identical `summary` values (both "Create endpoint", both "List
endpoints"). The page links to the reference introduction and names the
**Project webhooks** / **Organization webhooks** tags rather than
deep-linking a generated page. |

## Preview links

**Verified:** the new page returns 200 on the preview; the same path
returns 404 on production, confirming net-new content; the nav entry
renders on the preview build.

## Review instructions

1. Open the [PR
preview](https://docs-git-nikrichers-ctrl-1017-set-up-public-doc-fa3960-supabase.vercel.app/docs/guides/platform/webhooks)
and confirm the page renders as shown.
2. Confirm **Platform Webhooks** appears under **Platform > Project &
Account Management** in the sidebar, after **Personal Access Tokens**.
3. Confirm the five internal-guide values in the second row of the
needs-review table.
4. Decide with the Control Plane team whether the Studio UI ships wired
to the API, which determines when a dashboard section gets added: Studio
UI is slated for Q4, so it will not be shipped together.

Community & Support

  • Community Forum. Best for: help with building, discussion about database best practices.
  • GitHub Issues. Best for: bugs and errors you encounter using Supabase.
  • Email Support. Best for: problems with your database or infrastructure.
  • Discord. Best for: sharing your applications and hanging out with the community.

How it works

Supabase is a combination of open source tools. We’re building the features of Firebase using enterprise-grade, open source products. If the tools and communities exist, with an MIT, Apache 2, or equivalent open license, we will use and support that tool. If the tool doesn't exist, we build and open source it ourselves. Supabase is not a 1-to-1 mapping of Firebase. Our aim is to give developers a Firebase-like developer experience using open source tools.

Architecture

Supabase is a hosted platform. You can sign up and start using Supabase without installing anything. You can also self-host and develop locally.

Architecture

  • Postgres is an object-relational database system with over 30 years of active development that has earned it a strong reputation for reliability, feature robustness, and performance.
  • Realtime is an Elixir server that allows you to listen to PostgreSQL inserts, updates, and deletes using websockets. Realtime polls Postgres' built-in replication functionality for database changes, converts changes to JSON, then broadcasts the JSON over websockets to authorized clients.
  • PostgREST is a web server that turns your PostgreSQL database directly into a RESTful API.
  • GoTrue is a JWT-based authentication API that simplifies user sign-ups, logins, and session management in your applications.
  • Storage a RESTful API for managing files in S3, with Postgres handling permissions.
  • pg_graphql a PostgreSQL extension that exposes a GraphQL API.
  • postgres-meta is a RESTful API for managing your Postgres, allowing you to fetch tables, add roles, and run queries, etc.
  • Envoy is a cloud-native, high-performance edge and service proxy.

Client libraries

Our approach for client libraries is modular. Each sub-library is a standalone implementation for a single external system. This is one of the ways we support existing tools.
