Documentation changelog
Changes to this documentation and its published integration reference.
24 October 2026
Initial public documentation for merchant onboarding, invoices and catalog, payment statuses, balances and withdrawals, API authentication, merchant endpoints, public invoice reads, signed webhooks, and integration testing.
The downloadable OpenAPI covers the four authenticated merchant operations and public invoice retrieval. The checkout operations page explains the additional public checkout surface.
This is a documentation release date, not the introduction date of every described API feature. Future incompatible API changes need an explicit migration note; the current routes do not add a version prefix.
