Authorize.net ARB SSL certificate issue

Question

I am trying to create Authorize.net recurring subscriptions using PHP. I installed Composer, then used the composer.json as shown here https://github.com/AuthorizeNet/sample-code-php/blob/master/composer.json to install the Authorize.net SDK. Now I am trying to create a subscription on my sandbox account using the code found here: https://github.com/AuthorizeNet/sample-code-php/blob/master/RecurringBilling/create-subscription.php.

When I try to run this, it gives me the following error:

Fatal error: Uncaught exception 'Exception' with message 'Error getting valid response from api. Check log file for error details' in /home/tpmadmin/public_html/vendor/authorizenet/authorizenet/lib/net/authorize/api/controller/base/ApiOperationBase.php:122 Stack trace: #0 /home/tpmadmin/public_html/vendor/authorizenet/authorizenet/lib/net/authorize/api/controller/base/ApiOperationBase.php(104): net\authorize\api\controller\base\ApiOperationBase->execute('https://apitest...') #1 /home/tpmadmin/public_html/test.php(58): net\authorize\api\controller\base\ApiOperationBase->executeWithApiResponse('https://apitest...') #2 {main} thrown in /home/tpmadmin/public_html/vendor/authorizenet/authorizenet/lib/net/authorize/api/controller/base/ApiOperationBase.php on line 122

I checked the error log and it's showing me the following:

Note: in the message above I replaced my actual API_LOGIN_ID and TRANSACTION_KEY. The real message has the correct login information.

I don't know much about SSL certificates or what could be causing this. I've searched for hours on Google with no luck. Any help or advice would be awesome!

UPDATE: It's working on the live account, but not on the Sandbox account -_-

Answer 1

I had a similar issue, but I'm only wanting to authorize.

So, for my situation with authOnly SANDBOX requests I modified HttpClient to include curl_setopt($curl_request, CURLOPT_SSL_VERIFYPEER, false);

If I were doing more than authOnly requests, I'd probably use a different Authorize API (CIM via SOAP, for example)

One of my peers believes that PROD won't give the issue and shouldn't require curl_setopt($curl_request, CURLOPT_SSL_VERIFYPEER, false) but I haven't tested that thoroughly.
