First of all thank you for your reply,
I have indeed just noticed that this webhook expires on the same date as my acces_token, it is very annoying for the moment indeed.
To overcome this problem, I plan to force the obtaining of a new access_token each time my cron task is called which registers me for events.
I know I have to look at EventSub but I haven’t understood how it works yet, I haven’t understood why the use of “websockets” was mentioned when we are filling in URLs callback.
Currently EventSub is strictly equal to the classic Webhook in terms of registration / list process, etc. right?
