[Question](12-11-2025) How to track Visitors from our multiple website to our WHMCS and the product they buy

[ManagedCloud-Hosting]

How to track Visitors from multiple website we have to our WHMCS and the product they buy from these websites. Same Product Link is available for both websites...

1> A visitor buying from our abc.com website to our WHMCS Product Link and completes the purchase / payment. 

2> Another visitor buying from our xyz.com website to our WHMCS Product Link and completes the purchase / payment. 

How can we know from where or which website they are getting redirected and buying the service?

Thank you everyone!!

Yes, this can be done using WHMCS hooks.

On your website, you only need to modify the product link to include a source parameter, for example:

https://billing.yourdomain.com/cart.php?a=add&pid=5&src=abc

Here, the src parameter identifies the website from which the visitor came.

Then, in WHMCS, you can create a hook that runs when the product page loads. The hook can check whether the src parameter is present, and if it is, you can capture the value and save it in a custom table or a custom field for tracking purposes.

There are other methods as well, such as using the WHMCS affiliate system. Please let me know if you need any clarification or further help.
