API Changelog

Every breaking change to the PayConnect API ships as a new dated version. Select a version with the Payconnect-Version header — see Versioning. Additive (non-breaking) changes are not listed here; they can appear within any version and your integration should tolerate them.

2026-07-05.1 — General availability baseline​

  • First versioned release. This is the baseline: integrations without a Payconnect-Version header, and every account that onboarded before versioning, are pinned to 2026-07-05.1, and its behavior will not change.
