CiviCRM Community Forums (archive)

Hello,

I'm wondering if anyone has gotten their CiviContribute pages to work using the Authorize.net payment processor.

I'm currently on CiviCRM 1.7 for Drupal 5.x and I'm having problems when it comes to comparing the returned MD5 signature from the server with the MD5 sig. generated locally.

I've followed their instructions outlined in their AIM_guide in appendix E, however the key I generate and is different from what is returned from their server.

The transactions are getting approved, however it's just a matter of verifying that the server response came from their gateway.

Thanks for any help.
