Finishing a payment

The charge and refund function have a completion handler that has a PaymentResult object as a parameter. You can get info about the result of the transaction from this object. The completion handler will always be called when the payment flow is closing. Alternatively you can also get a payment result returned to you inside any of the ReceiptDelegate methods.

The PaymentResult object has a property called result which is one of the following ResultCode

public enum ResultCode: CaseIterable {
  case success
  case inProgress
  case failure(String)
  case cancelled
  case permissionDenied
  case noConnectivity
  case invalidToken
  case bluetoothDisabled
}

This result is useful to know if the payment was successful or not and why it may have been unsuccessful.

Yoco.charge(1000) { paymentResult in
  switch paymentResult.result {
  case .success, .inProgress:
    break
  default: // all failure cases
    break
  }
}
