  description: >-
    Simpro authenticates API applications with OAuth2 on the customer's own
    build. An account administrator registers an API application on the build
    and issues client credentials. The integration then requests an access
    token from https://{build}.simprosuite.com/oauth2/token - using the same
    build subdomain that staff use to log in to the Simpro portal - and passes
    it as `Authorization: Bearer ACCESS_TOKEN` on every request. Both the
    client credentials grant and the authorization code grant are supported,
    depending on how the application is registered. There is no global or
    self-service API host; credentials and tokens are always scoped to a
    specific build.
  flows:
  - clientCredentials
  - authorizationCode
