Hey there, Zoho recently set up a Canadian datacenter which uses a different API URL for refresh tokens.
zohoapis.ca is the URL for API calls and zohocloud.ca is needed for the token. I had to build this for myself and am happy to answer questions since the Zoho documentation doesn’t mention the Canadian dc but it means that any new Zoho accounts from Canada can’t use the current Make.com Zoho CRM integration.
