Use Hosted Checkout, Payment Links or the REST API. Your integration talks only to NRVE Pay; bank authorisation is handled by the hosted payment flow.
Create a test API key, create a payment session, redirect the customer to checkout_url, then fulfil only after a verified payment.completed webhook.
Send Authorization: Bearer nrve_test_… or nrve_live_…. Test keys use the NRVE Pay sandbox bank.
Send a unique Idempotency-Key header when creating a payment. Retrying the same request returns the original payment.
POST /v1/payment-links creates a hosted, single-use payment URL. This is suitable for email, CRM, phone orders and merchants without a checkout integration.
Register with POST /v1/webhook-endpoints. Events include payment.completed, payment.failed and payment.cancelled. Verify X-NRVE-Pay-Signature as HMAC-SHA256 over timestamp.body.
NRVE Pay records refunds for reconciliation, but refund execution remains a manual bank process. There is intentionally no API endpoint that moves refund funds.
