For Payment Provider partners, the Bango Payments product has two APIs:

• Bango Outbound Payment Provider API: Implemented by the payment provider. Receives requests from the Bango Platform to perform business operations, and responds to those requests.

• Bango Inbound Payment Provider API: Implemented by the Bango Platform. Receives requests from the payment provider to perform business operations, and responds to those requests.

Both requests and responses are expressed in the form of actions, where each action has a type and a type-specific payload. This allows both APIs to support a simple, consistent, extensible vocabulary of messages in both directions
