Changelog
This documentation tracks S2S CARD protocol v5.6.4. CentaPay monitors platform release announcements and updates these pages when the protocol changes.
Availability. CentaPay is pre-launch. Production is expected in Q4 2026, with sandbox access ahead of it. Coverage differs by market, and the payment methods available differ by market too. The coverage table on our main site is the single source for what is live where, and for current dates. Nothing in this documentation should be read as a service available today.
A dated entry is added here for every change that alters a request, a response, a callback or a hash formula. Corrections to wording are not listed.

There are no entries yet. The protocol version above is the first tracked release, and no request, response, callback or hash formula has changed since tracking began.
