What error do you see when you try to validate it?

There should be some additional information returned like connection timeout or challenge/token mismatch. What error response do you see?

There wasn't any specific but I'm pretty sure it has to be with web hook's get and post req. If is it fine for you? Then i could mail you screenshot to give you brief idea.

So what is the error you see? If it's about the verification part while subscribing it's related to a GET request. Most common errors would be your callback URL not responding at all or not responding properly (like echoing with additional markup or characters)

Could you please enlighten me with webhook documentation or AWS? I might think i blundered it in deploying in AWS. Thanks Lars!
