Is the web server restarted uppon account creation/deletion?

[RM6SS62]

I'm getting "502 Bad Gateway" (nginx ofc), I'd say, half of the time on account creation, and always on account deletion.
The web server being restarted there makes sense, but then how am I supposed to run the rest of the logic in my API, which depends of the data returned by DA?
Appreciate if you guys can provide some insight.

I can see at least the FPM service is restarted on user deletion which means I will never receive a server response when I run such task.
How are you guys handling this? Can someone please share?
