VoxyLine API

One merchant API for web and in-person payments.

Create server-side payment intents, use idempotent requests, and receive signed webhook events. Sensitive payment credentials are collected and stored by regulated payment providers, not VoxyLine.

1. Authenticate

Authorization: Bearer vx_test_...

Create and revoke keys from the merchant portal.

2. Create payment

POST /v1/payment-intents

Send amount in minor units, currency, and your order ID with an Idempotency-Key.

3. Listen

payment.succeeded

Verify each webhook signature before fulfilling an order.
