Mobile Inline Gateway

Payment flow

2. Merchant app calls the merchant backend

This is necessary since only the backends can be trusted to communicate securely.

3. The merchant's backend calls the Barion API

The endpoint is the ususal payment/start. The merchant does not have to add any new information to the request.

6. Merchant's app intializes the Barion SDK

import BarionSDK
...
let fastpayment = FastPayment(paymentClientSecret: paymentClientSecret, options: options)
fastpayment.present(from: self){ result in
  switch result {
    case let .success(paymentResult):
      // TODO handle successful payment result and validate it on your backend
      print("successful payment")
    case let .failure(error):
      // TODO handle the error
      print(error.errorCode)
  }
}
