Customize Error Messages for Payment Pages 2.0

This article describes how to customize error messages for Payment Pages 2.0. Error message customization is an optional step in implementing Payment Pages 2.0, but offers these benefits:

  • An error handling function gives you an easier mechanism to handle server-side error messages that are not handled in Zuora.
  • Using a custom error handling function, you can display the error messages in the Payment Page form in context to the user.

Customize Error Handling

You can customize error message handing in Payment Pages 2.0 in the following steps:

  1. Use the 1.2.0 or later version of zuora.js or zuora-min.js.
  2. Define a function to customize error handling using the Z.sendErrorMessageToHpm function.
  3. Render your Payment Page using the Z.renderWithErrorHandler function.
  4. If implementing an inline Payment Page with an external submit button, see Customize Error Messages in Advanced Integration for one additional step.

Define Custom Error Message Handling Function

In your error message handling function, define a custom error message that you want to display in your Payment Pages form, and pass that message to Payment Pages 2.0. Your custom error message handling function should take the following three input parameters:

  • key: Payment Pages form field name. See Payment Pages 2.0 Form Fields for the field names used in Payment Pages.
  • code: Error code returned when the client-side credit card validation fails. The following are the error codes and the corresponding error messages:
    • 001: Required field not completed
    • 002: Invalid card number
    • 003: Invalid card type
    • 004: Invalid CVV number
  • message: The error message returned from Zuora.

In your error message handling function, call the Z.sendErrorMessageToHpm function to send your custom error message to Payment Pages 2.0. The function takes the following input parameters:

  • key: The input parameter to your custom error message handling function as described above,
  • errorMessage: Customized error message to display in Payment Page. Note that this error message will not be localized in Payment Pages 2.0 form.

The following is a sample implementation of custom error message handling:

var errorMessageCallback = function(key, code, message) {
    var errorMessage = message;
    
    switch(key) {
        // Overwrite error messages generated by client-side validation.
        case "creditCardNumber":
            if(code == '001') {
                errorMessage = 'Card number required. Please input the card number first.';
            }else if(code == '002') {
                errorMessage = 'Number does not match credit card. Please try again.';
            }
            break;
        case "cardSecurityCode":
            break;
        case "creditCardExpirationYear":
            break;
        case "creditCardExpirationMonth":
            break;
        case "creditCardType":
            break;    
            
        // Overwrite error messages generated by the server-side validation.    
        case "error":
            errorMessage ="Validation failed on server-side, Please check your input values.";
            break;
    }
    
    // Use this function to show customized error message based on the key of the given field.
    Z.sendErrorMessageToHpm(key, errorMessage);    
    
    return;
};

Render Payment Pages 2.0 with Custom Error Handling

Use the alternate render function, Z.renderWithErrorHandler, instead of the Z.render function, to render your Payment Page with custom error messages.

The Z.renderWithErrorHandler function takes the same input parameter as the Z.render function and one additional parameter, the name of the custom error handling function.

The following is a sample call that uses the example error handling function, errorMessageCallback, defined in the previous section:

Z.renderWithErrorHandler (params, prepopulateFields, callback, errorMessageCallback);
