note: >-
  Derived by hand from the published Reporting API documentation and from the RFC 8414
  authorization-server metadata Jampp actually serves. There is no OpenAPI to run
  derive-authentication.py against — the only public contract is a GraphQL endpoint whose
  introspection is auth-gated.
summary:
  types: [oauth2]
  api_key_in: []
  oauth2_flows: [clientCredentials, authorizationCode]
  documented_flow: clientCredentials
  bearer_methods: [header]
schemes:
- name: OAuth2ClientCredentials
  type: oauth2
  flow: clientCredentials
  token_url: https://auth.jampp.com/v1/oauth/token
  request_content_type: application/x-www-form-urlencoded
  parameters:
  - grant_type (must be the exact string client_credentials)
  - client_id
  - client_secret
  response_fields: [access_token, token_type, expires_in]
  token_type: Bearer
  token_lifetime_seconds: 7200
  usage: 'Authorization: Bearer {access_token} on every Reporting API request'
  credential_issuance: https://app.jampp.com/users/credentials
  credential_note: >-
    Client ID / client secret pairs are self-issued from the Credentials section of the
    Silver dashboard. Jampp documents creating one key pair per integrating service so a
    single key can be revoked without affecting the others.

  note: >-
    Advertised in the authorization-server metadata (grant_types_supported also lists
    refresh_token) but not documented in the developer docs, which cover only the
    client-credentials flow. Recorded as advertised, not as a documented developer path.
