Did your Authorize.net sandbox account stop working?
Odds are, you need to update your cert.pem file in your Authorize.net library. Here’s how to fix:
Visit
http://curl.haxx.se/ca/cacert.pem
to download a fresh copy.
Then find your Authorize.net library directory containing your current cert.pem file. It is usually in a lib>SSL directory.
You need to replace the content of the one you have with the content of the one you downloaded.
NOTICE: you cannot just upload via ftp and walk away. The one you downloaded is named cacert.pem and your current one may be named just cert.pem. So you either need to
- delete your current file, upload and rename your new
- or open the cacert.pem file and copy all the content and then replace your current file’s code with your clipboard and save
