Setting up a firewall rule to accept post from external app but the app is getting block

Hi im trying to setup a firewall rule to let an exteral app post stuff to my website but I can’t figure out how to make it work.

here is the actual rule

(http.request.method eq “POST” and http.host contains “app.mailgun.com”)

But when sending a test from the app it is not working, cloudfare is challenging the app every time.

I cannot copy paste the header sent because the topic is only letting me put two url per post

I assume your action is set to “Allow”, correct?

I am not absolutely sure whether that only affects the firewall rule engine or also the other (general) security levels. @cloonan @cscharff?

Yes it is set to allow

Do you have any other Firewall rules, are you using Access and what are the details in Firewall Events?
