Hi there,
I get fields for creating activities from Zoho CRM API. Then, It is returned "Who_Id" text of which is "Contact Name". But, the type of "Who_Id" is bigint. When I see this text "Contact Name", I write a name generally. But, I get an error that "Who_Id" is not bigint from Zoho CRM API. I think the "Who_Id" text should be "Contact Id".
