+### Obtaining Zoho Calendar Client ID and Secret

+2. From within the API console page, go to "Applications".
+3. Click "ADD CLIENT" button top right and select "Server-based Applications".
+4. Fill in any information you want in the "Client Details" tab
+5. Go to tab "Client Secret" tab.
+6. Now copy the Client ID and Client Secret into your app keys in the Cal.com admin panel (`<Cal.com>/settings/admin/apps`).
+7. Back in Zoho API Console, set the Redirect URL for OAuth `<Cal.com URL>/api/integrations/zohocalendar/callback` replacing Cal.com URL with the URI at which your application runs.
+8. In the "Settings" section check the "Multi-DC" option if you wish to use the same OAuth credentials for all data centers.
+9. Click the "Save"/ "UPDATE" button at the bottom footer.
+10. You're good to go. Now you can easily add your Zoho Calendar integration in the Cal.com settings.
