Network error when checkoutAPIClient.createCardToken(...) called and Internet connectivity available about frames-ios

[harry-brown-cko]

Hi Kevin,

We're sorry to hear that you're experiencing issues with our SDK. We can see from our end that for your app you are using our SDK in headless mode and which errors are being raised, those being phone_number_invalid, phone_number_length_invalid and cvv_invalid.

Frames.NetworkError error 0 is a validation error returned from our backend. Note that in headless mode we currently do not validate input data before making the token request. We recommend these steps to avoid these errors in future:

Phone number validation

The tokens API has strict limits on phone number lengths. Please see here

We use PhoneNumberKit to validate phone numbers on our prebuilt UI, but only basic validation is required.

CVV Validation

We recommend using Frames.CardUtils.isValid(cvv: String, cardType: CardType) to validate CVVs before making calls to Frames.CheckoutAPIClient.createCardToken().

Reading errors after token request

It is also possible to react to errors returned from our SDK and prompt the user to fix invalid fields. Please see below:

checkoutApiClient.createCardToken(card: card) { result in
  if case .failure(.checkout(_, _, let errorCodes)) = result {
    for errorCode in errorCodes {
      switch errorCode {
      case "card_number_invalid":
        // handle error
      case "cvv_invalid":
        // handle error
      case "card_expired":
        // handle error
      case "payment_method_invalid":
        // handle error
      case "card_expiry_year_invalid":
        // handle error
      case "request_json_invalid":
        // handle error
      case "card_expiry_year_required":
        // handle error
      case "card_expiry_month_invalid":
        // handle error
      case "phone_number_invalid":
        // handle error
      case "phone_number_length_invalid":
        // handle error
      default:
        continue
      }
    }
  }
}
