Authentication

Merchant API credentials

Server-to-server calls to tokenization, checkout, and payment-link endpoints use merchant API credentials. Credential format and issuance are provided during merchant onboarding.

Send merchant credentials as a bearer token:

Authorization: Bearer <merchant-api-key>

Do not embed merchant credentials in browser or mobile client code.
