I found in the documentation : 

//Replace 'BGBQIIE7H253K6' with the client id of the application using which the webhook is created

 And another one I found is :

Note:

Please configure your webhook URL to respond to the webhook verification and webhook notification requests as per the verification protocol explained above. The client ID (Application ID) that will be sent to webhooks created from the Adobe Sign web application will be - UB7E5BXCXY
