Integration with KARTRA

Integration with KARTRA

When I trigger an action in Kartra, I want to create a contact in Zoho Crm. Usually we use Zapier for this.
But when I create a zap - the account is only .COM and .AU 

Obviously my account is in India and the ERROR_invalid_client

How do I integrate zap with zoho? Is there some api I use and connect via Web Hooks?
