Cint Projects API

openapi: 3.0.3
info:
  title: Demand Accounts Projects API
  description: 'Cint''s demand ordering API is REST oriented. It has predictable resource based URLs, accepts JSON-encoded request bodies, returns JSON-encoded responses, and uses standard HTTP response codes, authentication, and verbs. Error responses are also JSON-encoded and follow a standard format, providing a unique error ID and detailed information about what went wrong.


    Authentication is handled via bearer tokens passed in the `Authorization` header. All requests must also include a `Cint-API-Version` header with a date in `YYYY-MM-DD` format to specify the desired API version. Depending on the version you use, endpoint behavior may differ as we improve our API with every version release.


    While many operations work on a single object per request, the demand ordering API also provides asynchronous batch endpoints for performing bulk updates efficiently on certain resources. For safety, `POST` requests support an `Idempotency-Key` header to allow for safe retries without accidentally performing the same operation twice.
