providerId: outreach
notes: >-
  The published OpenAPI declares NO oauth2 securityScheme — it models only `bearerAuth` and `s2sAuthToken`
  as plain HTTP bearer JWTs — so `derive-oauth-scopes.py` finds zero scopes. The scope model is real and
  fully documented in prose, and the OAuth 2.1 authorization-server metadata at
  https://api.outreach.io/.well-known/oauth-authorization-server declares its own `scopes_supported`. This
  file therefore comes from the docs, not the spec. Outreach does not publish a single enumerated table of
  every OAuth scope; the authoritative list is rendered in the Outreach app's "API access" configuration
  tab, which is behind a customer login. Only scopes Outreach actually names in public are recorded below —
  nothing was extrapolated across resources.
grammar:
  form: <pluralResource>.<level>
  levels:
  - read
  - write
  - delete
  - all
  additive: false
  additive_note: Scopes are NOT additive — `prospects.write` grants no read access. `all` implies
    read + write + delete.
  request_form: space-separated, URL-encoded, in the `scope` query parameter of /oauth/authorize
  on_missing_scope: 403 with error id `unauthorizedOauthScope`
  post_scope_check: OAuth scope is the front gate only; the user's Outreach governance/RBAC profile is
    evaluated separately and returns 403 `unauthorizedRequest` on failure.

scope_source_note: >-
  Every scope above is published by Outreach. The `<resource>.<level>` rows for accounts, auditLogs, calls,
  events, imports, kaiaRecordings, mailings, opportunities, prospects, sequenceStates, sequences, snippets,
  tasks, templates, users and webhooks are the S2S "Available scopes" table transcribed verbatim from
  https://developers.outreach.io/api/s2s-access — Outreach states S2S scopes are a SUBSET of the OAuth
  scopes, so each also exists on the OAuth surface. `batches.read`/`batches.write` come from the Bulk API
  page. `prospects.all` is additionally declared machine-readably in the authorization-server metadata.
gaps:
- The REST API exposes 51 tagged resources but only 16 resource families appear in any published scope list;
  scopes for the remaining resources exist but are enumerated only inside the authenticated app-configuration
  UI.
- The OpenAPI declares no oauth2 securityScheme and no per-operation scope requirements, so a generated
  client cannot tell which scope any given call needs.
- The MCP authorization-server metadata advertises only the prospects.all scope in scopes_supported, which
  does not cover the 41 tools it serves (accounts, opportunities, sequences, tasks, teams, users, Kaia).
