This section documents Fingo Pay’s REST API. Use the interactive playground to test requests against https://api.fingopay.io with your API key.

​
Authentication

All API endpoints use Bearer authentication. Provide your API key as a Bearer token in the Authorization header.
For POST endpoints, include an Idempotency-Key header so retries do not create duplicate operations.

​
Enterprise-only fields in API requests

Some endpoints accept optional fields that are only relevant for enterprise integrations (aggregators, dedicated shortcodes, sub-merchants). These fields are marked with the ENTERPRISE badge throughout this reference.
Send only required fields unless your integration needs enterprise routing behavior. Over-specifying optional fields is a common source of integration errors.

Enterprise integration guide

Learn how to set up dedicated shortcodes, sub-merchants, and enterprise routing patterns.
