If you are using preconditions with a JSU post function, they can be evaluated in the following ways:

- True (Precondition must be true to execute a post function)
- False (Precondition must be false to execute a post function)

The precondition setting is available on our post function configuration pages, and it is set to **True** by default. You can learn more about our preconditions in [Workflow Preconditions](https://appfire.atlassian.net/wiki/spaces/JSUCLOUD/pages/12518025). See the Preconditions for Post Functions [uses cases](https://appfire.atlassian.net/wiki/spaces/JSUCLOUD/pages/12518052) for examples.
