A: Hello c6ac9db651284e3890e90141fdfc5076,

Thank you for reaching out!

TidyCal does not have a direct integration with Zoho One CRM.
We do however leave our API's open for users to create any integration they need and you can create API keys here https://tidycal.com/integrations/oauth and view the API developer docs here: https://tidycal.com/developer/docs/.
The API uses the conventional OAuth 2.0 protocol for authentication.

Also, please check out this guide on how to create API requests in the Postman app - https://help.sendfox.com/article/309-creating-api-requests

We trust this will help.

Have a fabulous day and best regards from the Team Originals!
