Time-based trigger

You can schedule your function's execution using the Time-based trigger in the settings panel. It lets you trigger the function every x minutes or with a Crontab expression:

Every x minutes

You can trigger a function at periodic intervals, expressed in minutes. This trigger method runs the UbiFunction's main function. The minimum and maximum values allowed in this field are 1 and 60 minutes, respectively.

Crontab expression

A cron expression is a string made up of five subexpressions, or fields, that define the schedule. These fields are separated by whitespace and can contain any allowed values, with various combinations of the allowed characters for each field.
