Introduction
Welcome to the Paytrie API documentation
v1 is sunset — do not use
The v1 API was sunset on August 21, 2026 and no longer accepts
requests: v1 endpoints return 410 Gone. These pages are kept for reference
only, to help you map an existing v1 integration onto v2.
All new and existing integrations must use v2. See the migration guide to get started.
