Can I limit my execution to be run by certain IP's.

I am listening to a webhook with a function I want to limit that the function so that only certain IP's ie from where the webhooks origin can call that function. Can I do that in Appwrite,

TL;DR
The user is asking how to add authentication to an Apple in-app purchase notification webhook. Other users suggest verifying the signed payload and using a secret or auth header. One user suggests getting the IP from the user's API session, but others point out that it can be faked. The solution proposed is passing the IP manually to the function and checking it internally. The user also asks how to add a project ID in the header, and it is suggested to use a firewall or WAF like Cloudflare. Ultimately, it is mentioned that there is no direct way to limit execution to certain IPs in Appwrite.

There is not a direct way to do it directly in Appwrite

Then it's not possible the solution I proposed. The only way I see it is by passing manually the IP to the function and checking the IP with a condition inside it

The problem I see there is that someone could fake the IP so I don't see it as a solution if you need this for security reasons

A potential solution could be getting the IP from the users API by checking the session. However if the user logins in a differente IP, it will not manage to create anything

Usually, you're able to configure some sort of secret or auth header. What webhook are you using?

Besides that, have you tried dumping all the headers in the Appwrite function to see if there's anything you can use?

According to this, there's a signed payload, so you can verify the signed payload in your function code:
