Edit multiple response code mappings at once by exporting a CSV file, modifying it, and importing it back.

1. On the Response Codes tab, click the Menu icon in the upper right, and then click Bulk Edit Response Codes.
2. In the Bulk Edit Response Codes window, click Export CSV, and then select one of the following options to export the code list as the base for your edits:

   • Master Code List: A CSV template that contains gateway response codes and suggested code mappings. The Master Code List might not contain all response codes that apply to your gateway. Verify with your gateway that all codes are listed and mapped correctly.

   • My Code List: A CSV file that contains the current code list and mappings.

3. Edit the exported CSV file to include new response codes in your mapping. Ensure that the file meets the following requirements:

   • Gateway names and code labels are case sensitive.

     Note: You must use the payment gateway type names. To identify the gateway type names, use the List all payment gateways REST API. In the response, the type field of each returned gateway indicates the type name of that gateway.

   • You can map codes only to existing code labels. To add a new code label, use the UI (Menu > Edit Code Labels > Create Code Label).

   • Duplicate response codes are not allowed.

     Note: New codes that you add to your CSV file are not added to the Master Code List.
4. In the Bulk Edit Response Codes window, select your edited CSV file from your computer, and then click Import CSV.

   The new code list overrides the existing code configuration.
