I request a feature that will definitely be an advantage for WHMCS.
Facebook pixel conversion api. Such an integration is a must for a Whmcs-style e-commerce software. Most users including me facebook pixel, google ads etc. We use intermediaries. To advertise. Facebook pixel is currently working very inefficiently. Therefore, it is necessary to make an integration with the api on the server side. If whmcs did such an integration instead of other middleware software, we would both understand that the money we paid was not wasted, and it would be ahead of other competitors. This feature is essential for today.
I'm typing with google translate.
Sorry for the broken english.
