How App2App Fits into Pay-Connect

App2App is an extension of the Pay-Connect platform, not a standalone integration. It uses the same infrastructure and credentials as your API integration. It offers fast, low-overhead payment processing for charge, revert, and refund operations.

Terminal pairing

Terminal pairing is always initialized by the backend

Payment processing

Payment processing remains consistent with API integrations
  • You are building an Android POS application
  • You want a fast, low-overhead integration
  • Backend involvement during payment is not required
  • The POS and payment apps run on the same device

​
Supported Operations

Supported Operations
App2App supports a focused set of payment operations only:
  • Charge - Process a payment
  • Revert - Cancel a transaction before settlement
  • Refund - Return funds after settlement
All other functionality is available exclusively through API integration.
