Patch a Biller

Adfin API (1.0.0)

Adfin uses OAuth 2.0 access tokens to authenticate all API requests.

There are two contexts in which tokens are issued:

  • Biller Access Tokens — Generated via the Authorization Code flow when a biller connects their Adfin account. These tokens grant access to that biller's data (invoices, payment requests, customers, etc.).

  • Platform Access Tokens — Generated via the Client Credentials flow for Adfin's own integrations and system events. These tokens authenticate Adfin as the platform itself (not as a specific biller) and are required for endpoints like /api/webhook.
