I have done the following:
Created api/endpoint and url Tested locally/externally Added new app, selected Webhook and subscribed to leadgen
So far all this has been fine and I assume verified ok as gave me Webhook settings and I can see it did hit my Get request on endpoint after clicking subscribe option. But when I click the 'Test' option on the same page it says it was successful but it appears nothing has hit the endpoint on checking logs.
I looked to use the Lead testing tool but the app was not available to pick from, is there another way to determine what is being sent (payload etc) and the result behind this button?

For approximately two weeks now, our webhook has ceased to send us messages.
Despite successful authentication, no messages are being echoed through the webhook. Interestingly, when testing with Postman, I am able to retrieve logs, indicating that the issue may be specific to interactions with Meta.

i have created a facebook app. the purpose is to get the details when someone make a comment on a post or interact with the page. I have set up the webhook url, got the challenge and the process is complete. After that in order to get the feeds i have subscribed the feeds under page and some other page related(i have set up the permissions which are requested in facebook documents and even tried all the permission available there) permissions under the permissions dropdown. But i am not getting any hit on my api when i make a comment. I and tried commenting using the user which created the page, page as user, and even with the graph api. but its not sending any response to api. So i thought maybe something to do with the API. But when i tried the messaging option and set up the webhook for that, i am getting the message through the webhook and its working fine. So that means the API is not the issue, and something to do with facebook permission or some other things. So i subscribed to every permission in that page and i am still ot getting any response for the feeds.
So an i missing something? For the facebook page webhook? If anyone went through this kind of an issue please provide your insight. I am stuck with this for a while and seems to going in circle.

Hi everyone. I am developing an api where I want to receive feed updates from a Facebook page. I created the backend and configured it with the webhook pages, when I click on the test button of the feed, green check its shown and "The sample update was successfully sent to your server." text its display, but no request is sent; When I click on the send_cart test button I receive a request on my backend (this is only for test reasons, I am not interested receive send_cart requests). I'm not sure if it's some issue with the feed test button. If anyone has an idea how to solve this or knows how to make test requests for the feed in another way, it would be very helpful to me. PD: The url on my backend for the test its a POST url.

After I was passed the app review(page_messaging) I switched my app from development mode to Live mode. I've tested with the public user who doesn't have a role on the app, but the webhook still not trigger. Anyone know how to make the webhook can be triggered by public user. please help me T.T
Thank you in advance
