Zoho authtoken depreciation imminent. Support ends 2/28/21

Just FYI Zoho has dropped the ball with emailing customers about this. I've seen many people caught unawares. So I'm posting this to hopefully bring visibility to others they might not have communicated this to. The gist is their authtoken is going away and OAUTH only is supported. more details here: https://help.zoho.com/portal/en/community/topic/deprecating-support-for-authtokens and https://www.zoho.com/analytics/help/oauth-authentication-model.html
