Response Reason Code: 13

Response Reason Text: The merchant Login ID is invalid or the account is inactive.

This error indicates you are either posting the incorrect API Login ID within your script, connecting to a server that does not recognize your account, or using an account which is inactive. Please follow these steps to ensure that your software is connecting correctly:

• If you are posting your transaction requests to the gateway URLs https://test.authorize.net/gateway/transact.dll or https://certification.authorize.net/gateway/transact.dll and you are using an account given to you by an Authorize.Net Reseller or from Authorize.Net Sales, you may encounter this error. The gateway URLs mentioned above only work with specific test accounts, available upon request by completing the form at https://developer.authorize.net/testaccount/

Try posting your transaction request to https://secure.authorize.net/gateway/transact.dll instead. If you need to submit a test transaction, you may do so by setting the field x_test_request to "TRUE". You may then remove x_test_request or set it to "FALSE" when you have completed your testing.

Note: If you are integrating your website with Advanced Integration Method (AIM) using PHP, please be aware that the gateway URL is listed twice--once in the cURL configuration, and once again in the main body of the code. Using the test gateway URL in the cURL section of the code will create an Error 13 as cURL would connect to the incorrect server.

• Please check your script and verify you are posting the API Login ID for the account in question. If you are not posting the correct API Login ID, or if you are not sending an API Login ID, please edit the script and confirm that the field x_login is set to the API Login ID that you may obtain from the Authorize.Net Merchant Interface. Please see the Merchant Integration Guide at http://www.authorize.net/support/merchant_guide.pdf for instructions on obtaining the API Login ID. For further information on the API Login ID, Transaction Key, or Test Mode, please check out our online video tutorials at http://www.authorize.net/videos .
   
• If you are unable to log into your Authorize.Net Merchant Interface, this could indicate that your account is inactive. If this is the case please contact us directly to reactivate the account. You can reach us toll-free at:
