Send a notification to URL Or email when a member joins a server

[younes-dro]

Hello,
I need to update my site's database when a member joins, leaves, and rejoins again my discord server.

use case:
Suppose a member joins my server, I give him his role depends on his adherence to my site.
But, if the client leaves the server and joins it again , it loses its role.
I want to know, can my discord server trigger an event that I can catch by sending either
1 - a call to a URL of my site.
2 - or simply send an email to the member containing a url that the client opens it to update this data.

Thanks
