2023-01-16 API version end-of-life

As of 31 January 2025 the 2023-01-16 version of the API is no longer available.

Our new API versions have improved reliability and performance, plus additional features such as embedded foreign exchange at time of ordering.

All affected customers were notified ahead of time. As of today requests for the specific version using the X-Api-Version header will respond with a 410 Gone error code. Requests without this header will default to the current API version.

For more details on our versioning strategy see the API versioning page.
