Callable

Callable Triggers refer to the triggers invoked from another process app. For example, let us consider Process App A which is already designed and Process App B that uses a callable trigger. In the above example, it is not defined which flow triggers Process App B. Instead, a call a subflow task is added in Process App A to trigger Process App B. After the callable task is added, the system automatically links these two flows and adds Process App A as a trigger to Process App B. On the Callable Triggers window, you can see the name of Process App A (as a trigger) and any other triggers/process applications that trigger Process App B.

Configure Callable Trigger

To configure a Callable Trigger, follow the below steps:

1. After you log in to the Process App, it lands you on the Flow tab.
2. On the right pane, click Callable under Triggers.
3. On the Callable Trigger window, by default, the Variables tab is selected.
4. On the Variables page, click + Variable to add process variables. Variables are passed from parent process to child process app.
5. Select a Data Type (String, Boolean, Number, Date) from the drop-down list.
6. Click Save.
7. Similarly, you can add multiple variables with different data types.
8. Click the Process App tab.
9. You can find the Process Apps. Select a Process App to trigger this workflow.
10. Click Done.
