To further investigate this issue, we’d need you to send us some more details in our support channel.
The problem of not receiving web-hook calls might be on the receiving application’s side. To make sure this isn’t the case, you can compare a test call to the one you’re receiving in your application.
To do this, please first create a Request Bin. Then, go to the settings page on your Contentful web interface. Configure Request Bin as an additional web-hook endpoint. Now you should be able to perform the test request and compare the response with that of your application. After this, you should be able to tell whether the problem is on your side. If that’s the case, go to the Contentful interface, and open an entry or asset that has the web-hook problem. Copy the URL for that entry/asset, and send it to us.
The last thing we’ll need is permission to access your content, to check where exactly the problem is.
