Why can't I get my callback to work.
Last Updated 3 years ago

If you are experiencing issues with your callback URL and you are certain it is correct. Check your SSL Certificate. 

The issue with the callback is due to wildcard certificates. The issue here is that Optimal Payments are requesting a specific Web Site URL. The server responds with a certificate that doesn’t quite match (because of the wildcard * in the certificate). This causes the server to give us a warning. The warning will cause for us to not send the callback.

This is for optimal payment and Desjardin,

Ensure you purchase a specific SSL certificate for your host.
