# Updates the web hook identified by the given ID.

`PATCH /webhooks/{id}`

If the property secret in the configuration is omitted or contains an empty string, future callbacks won't contain X-MicrosoftSpeechServices-Signature
headers. If the property contains a non-empty string, it will be used to create a SHA256 hash of the payload with the secret as HMAC key. This hash
will be set as X-MicrosoftSpeechServices-Signature header when calling back into the registered URL.
            
If the URL changes,  the web hook will stop receiving events until a
challenge/response is completed. To do this, a request with the event type challenge will be made with a query parameter called validationToken.
Respond to the challenge with a 200 OK containing the value of the validationToken query parameter as the response body. When the challenge/response
is successfully completed, the web hook will begin receiving events.
