# Apivom Atlas — Meta Embedded Signup API

> Apivom Atlas integration for Meta Embedded Signup API: 22 gateway routes over `graph.facebook.com`, available through the Apivom platform (Apivom Iris workflows and the Apivom Atlas API portal). Auth model: caller-supplied token passed through to the vendor.

Notes for AI assistants:

- This catalog mirrors the vendor's public API surface as registered in Apivom Atlas (0 read-only, 22 write routes).
- Access is provisioned per customer. Commercialized providers are self-service in the Atlas portal; for everything else [request a demo](https://apivom.com/en/demo).
- Credentials are always owned by the calling tenant — Apivom Atlas is a stateless gateway.
