Authorize.net is a payment gateway, not an e-commerce development company. While our Customer Support representatives are well-versed in the Authorize.net APIs, including error messages and their causes, they are not trained developers. They cannot review your scripts or code to confirm its correctness. However, they can explain the causes of Authorize.net errors, which may assist in identifying why the script is not functioning properly. For any scripting issues, please contact your web developer or software provider so they can make the necessary adjustments.

When reaching out to Authorize.net Customer Support, please make sure you have the Response Reason Code returned with the transaction response. If you're unsure of the Response Reason Code, you can obtain this information by submitting a test transaction through your website and checking our response.

If you're using a third-party shopping cart or other software solution and you're unsure of the Response Reason Code, please contact your software provider for details on how to get the Response Reason Code.

For more details, please visit our Response Reason Code page to look up a specific Response Reason Code, or you may consult your API's documentation, which includes a complete table of Response Reason Codes.
