Hi there, as the title says, I'm trying to configure Plesk PHP values on a subscription level by a WHMCS product addon or configurable option. I didn't find any information in the docs. Do you guys have an Idea how to accomplish this? With best regards

Hello there! My goal is to use the {$invoice_subscription_id} variable in a product email. But for this I need a hook that makes this variable usable with the EmailPreSend" hook. I have never worked with WHMCS Hooks myself. Is there anyone here who has a code snippet for it? Best regards
