Overview
Once you set up a Function API, Zoho Connect lets you manage all your Function API configurations from one place. You can create new configurations to set up integrations, edit existing ones to update how your applications communicate, and disable or delete the configurations you no longer need.

Execution logs
The execution logs in each Function API configuration record the details of every request handler activity over the past year. This includes the execution time, status, parameters passed, and the data returned. You can refer to these logs to monitor your Function API's performance and troubleshoot any issues.
Execution limit
Your network has a daily limit on the number of times a Function API can run. Function API is available only on the Ultimate plan, with a limit of 20,000 executions per day. You can create up to 100 Function API configurations in your network.
Once the daily limit is reached, all Function APIs in your network will be paused for the rest of the day and will resume at 12:00 AM based on your network's data center location.
You can view the number of executions used for the day in the Usage Details section at the top-right corner of the Function API page.
