  description: >-
    Application authorization (2-legged OAuth). The application exchanges its client_id and
    client_secret for an application access token that acts on the app's own behalf.
  token_urls:
    production: https://api.dwolla.com/token
    sandbox: https://api-sandbox.dwolla.com/token
  grant_type: client_credentials
  token_request_auth: "HTTP Basic — Authorization: Basic base64(client_id:client_secret)"
  token_lifetime: "3600s (one hour); no refresh token — re-exchange credentials on expiry"
  api_request_auth: "Authorization: Bearer {access_token}"
request_headers:
  Accept: application/vnd.dwolla.v1.hal+json
  Content-Type: application/vnd.dwolla.v1.hal+json (or application/json)
scopes:
  note: >-
    The client-credentials application flow does not use scopes. Scope errors (InvalidScopes) can be
    returned for endpoints requiring specific granted permissions; a public scope reference was not
    located, so no scopes/ artifact is emitted (see errors/dwolla-problem-types.yml InvalidScopes).
