Raphaël Bosi c52c983b90 Source app About description from README and improve internal app READMEs (#22012)
## What

- The SDK manifest build now sources an app's `aboutDescription` (the
long-form "About" tab content) from its `README.md`. An explicit
`aboutDescription` in the config still wins, matching the existing
marketplace CDN fallback.
- Removed the now-duplicated `aboutDescription` from internal app
configs and deleted the standalone `ABOUT_DESCRIPTION` constant files.
- Rewrote internal app READMEs to read as user-facing About content:
stripped developer/build/source-path noise, and expanded the thin ones.
`call-recording` and `self-hosting` (one-liners over substantial apps)
and `people-data-labs` were rewritten from a close reading of the code;
`twenty-exa` was verified for accuracy.
- Added a unit test (and a fixture README) covering README →
`aboutDescription` in the build.

## Why

The README and the About description were maintained separately and
drifted. Making the README the single source keeps the About tab
accurate and removes duplicated copy.

## Notes for reviewers

- Internal apps depend on the published `twenty-sdk`, so the build
change takes effect for them after an SDK release + dependency bump.
Until then, published apps still get README → `aboutDescription` via the
marketplace CDN sync.
- Standard/Custom app descriptions are unchanged (they are resolved in
the frontend, not via the manifest).

Self Hosting

The Self Hosting app collects sign-up telemetry from self-hosted Twenty instances and turns it into structured CRM records. Each time a user signs up on a self-hosted instance, the app records who they are, which instance they belong to, and automatically links them to a matching Person in your workspace.

What it does

  • Receives sign-up events from self-hosted instances through a public telemetry webhook.
  • Creates or updates a Self Hosting User record for each real sign-up, keyed by email address.
  • Automatically matches every Self Hosting User to an existing Person by email, creating a new Person when none is found, and keeps that link up to date as the data changes.
  • Filters out test and example sign-ups so they never enter your CRM.
  • Carries a rich set of person and company enrichment fields so each sign-up can be augmented with firmographic data.

What it adds to your workspace

Self Hosting User object

A new object, Self Hosting Users, stores one record per self-hosted sign-up. Its fields include:

  • Identity: Name, Email, Domain, Locale. The webhook only populates Name, Email, and Locale; Domain exists on the object but is not filled in by the sign-up flow.
  • Instance: Server URL, Server ID, User ID, User Workspace ID.
  • Relations: Person, the matched standard Person record for this user.
  • Aggregate: Number of Emails with Same Domain, a count of users sharing the same business domain. This field is part of the data model but is not populated by the app's own ingestion or matching logic.
  • Enrichment state: Is Enriched, Tried To Be Enriched, Is Personal Email, Is Twenty.
  • Person enrichment: City, Country, Job Function, Job Title, LinkedIn, Seniority.
  • Company enrichment: Name, Description, Industry, Industries, Employees, Founded Year, Annual Revenue, Funding Latest Stage, Funding Total Amount, Alexa Rank, LinkedIn, Tags, Tech.

Person relation

The standard Person object gains a Self hosting users relation, so you can see every self-hosted sign-up tied to a given person directly from their record.

View and navigation

A Self hosting users table view exposes all of the fields above as columns and is added to the left sidebar for quick access.

Role

The app ships a default role with read, update, and soft-delete permissions over workspace records. Permanent deletion is not granted.

How sign-up data flows in

The app exposes an unauthenticated HTTP endpoint that self-hosted instances post telemetry to:

  • Method: POST
  • Path: /webhook/telemetry

A request is processed only when its action is user_signup; any other event type is acknowledged and ignored. The payload carries the user's email, first and last name, locale, the originating server URL and server ID, and workspace identifiers.

When a valid sign-up arrives:

  1. Non-signup events are acknowledged and ignored first; then sign-ups with no email are skipped; then sign-ups whose email contains test or example (case-insensitive) are ignored.
  2. If a Self Hosting User already exists for that email, it is updated with the latest details; otherwise a new one is created. The app persists Name, Email, Locale, Server URL, Server ID, User ID, and User Workspace ID; Domain and the enrichment fields are left for separate processes.
  3. Whenever a Self Hosting User is created or its email changes, the app looks for a Person with the same email. If one exists it links them; if not, it creates a Person and links it. Records that already have a matched Person and an unchanged email are left untouched.

Configuration

This app requires no server or application variables. To send data into it, point a self-hosted Twenty instance's telemetry at the webhook path above on the workspace where this app is installed.

Limitations

  • The telemetry webhook is intentionally unauthenticated and performs no signature or shared-secret verification. Any client that can reach the endpoint can submit sign-up events, so it should only be exposed to trusted self-hosted instances.
  • Test/example filtering is a simple substring match: any email containing test or example anywhere is excluded, even if it is a legitimate address.
  • The enrichment fields and the Domain field are part of the data model but are populated by separate processes; the app itself ingests sign-ups and performs Person matching.
