  notes: >-
    Creatio is a multi-tenant platform; the API host is per instance
    (https://<instance>.creatio.com). All external requests to OData and
    DataService require authentication. Forms (cookie) authentication is the
    recommended method for service-to-service integration; OAuth 2.0 is the
    recommended method for integrated applications.

    description: >-
      Cookie-based forms authentication via the AuthService.svc web service.
      POST credentials to /ServiceModel/AuthService.svc/Login, then send the
      returned cookies (.ASPXAUTH, BPMLOADER, BPMCSRF, UserName) on subsequent
      requests. The BPMCSRF cookie value must also be echoed in the BPMCSRF
      request header, and requests set the ForceUseSession: true header.
    endpoints:
      login: /ServiceModel/AuthService.svc/Login
    headers: [BPMCSRF, ForceUseSession]

    description: >-
      OAuth 2.0 authorization for integrated applications. An OAuth client
      (client id + client secret) is registered in Creatio's Identity Service,
      which issues bearer access tokens presented on API requests. Grant type
      is client credentials (server-to-server). The token endpoint lives on the
      Identity Service configured for the instance.
