Since Nov 20th, my existing webhooks into Zoho Cliq stopped working because of migration to OAuth2. 

I tried to follow the instructions on the api page to generate the access token ... https://www.zoho.com/cliq/help/restapi/v2/#authentication

I was able to do that successfully, but the documentation from using the access_token from the API to using it in the webhook is incomplete, and even the examples on the page don't explain where they got the authtoken from.  Need help to set this up urgently so that I can get my bots back into play. 

From Postman, a simple example I'd doing is https://cliq.zoho.in/api/v2/bots/zohosprintsbot/incoming?Zoho-oauthtoken=1000.XXXXX.YYYYY which is giving me a 401 error.  The access token received is 1000.XXXXX.YYYYY

but the example on the help site use authtoken=ZZZZZ and there is no explanation where ZZZZZ came from.
