Restricted access for the Facebook crawler

Hi everyone,

When I share this link on the Facebook debugger, I receive an error indicating that the Facebook crawler is unable to access the link, with a response code of 403. These are the links I use to track statistics for clicks on my website and to control redirection based on the user’s country.

Here is an example of how the link looks: https://domain.com/category/article/?WebApikey=SEC1659GEN1622

Facebook is unable to access this link, but it can access the https://domain.com/category/article/ part without the ?WebApikey=SEC1659GEN1622 parameter.

I have tried modifying/deleting the .htaccess and robots.txt files, but the restriction is not changing. I’m not receiving any errors in the logs.

Can someone please help me figure out where the problem lies?
