Versioning

The current version of the Crezco Payables API is 2025-01-31

Versioning is handled using the Crezco-Version header. Where the header contains no version information the default version of the API will be used, currently 2024-06-30. To use a specific version of the API set the header as follows:

Crezco-Version: yyyy-MM-dd

where the value is an ISO 8601 date when the API was released. For example:

  • Crezco-Version: 2025-01-31 - use the version of the API released end of January 2025

Backward incompatible changes will result in a new version of the API being released. The version number will correspond to the date of the release.

When the header is set to a value that is not supported in the called API you will receive a 406 - Not Acceptable response. The body will contain a representation of the valid versions that the API supports.
