Mandates/DDIs must be created under a specific scheme (e.g. the SEPA CORE or Bacs scheme) and must also be linked to a Creditor Scheme ID (CSID) in SEPA or a Service User Number (SUN) for Bacs. (To determine your CSID/SUN use the List Scheme service.
Depending on the configuration of your Creditor Scheme your mandates/DDI will be created in a specific status.
Regardless of the scheme, Direct Debit payments can only be created against an Active mandate.

Important: Endpoints may be extended from time to time and any changes we make will follow our Versioning and Backward Compatibility rules. This means that the code that you write today must be designed to be robust enough to handle any future changes (where a new object is added to (or removed from) a specific API response, for example).
