Cardless

Cardless Partner API

The Cardless partner API surface used by brands to embed a co-branded credit card program: partner authentication (Basic-auth exchange of a partner-signed JWT for a bearer access token), application submission and decisioning, account servicing, payments, transactions and disputes. Documentation and the OpenAPI fragments that back it are gated behind a partner login at docs.cardless.com; the production API host answers unauthenticated requests with HTTP 401.
