The Voucher API lets you issue vouchers, control their lifecycle (activate, reserve, charge, refund, recharge), and manage client access. It is built on OAuth 2 client credentials and supports both production and sandbox environments.

Quickstart

Set up a client, get credentials, create your first voucher, and run through the full charge flow.

Error codes

Error response format and all validation error codes grouped by operation.

Authentication

The Voucher API has its own OAuth 2 server and a pin-based credential exchange. See the quickstart for the token endpoint and setup steps.
