Sharing most of your keys and the URL of your TTI instance?
Your application & device ids look strange - like you are trying for some security by obfuscation which is a bit pointless with the security already provided and just makes understanding things when you come to debug issues like this.

And then read the web hook documentation as your screen shot doesn’t show the required permission which would be the root of your problem. Oh, and the wrong path, you’ve used the one for the REST interface, not for the web hook.
If it still doesn’t work when you’ve turned on the correct permission, we’ll need to figure out your 11 headers when only two are needed and one more is recommended.
Don’t worry about your English, you can be assured that you all extract every ounce of payback when we try to speak French on holiday.
