Current version

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

How to specify a specific version

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 2025-01-31. To use a specific version of the API set the header as followsCrezco-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.

Not setting the version in the header

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.
