Adding Triggers to a Flow

If you had created a flow without a trigger, you can add one or more triggers to it at any time.

A flow that was created without a trigger has its input and output parameters defined in the Flow Inputs & Outputs dialog that you can access by clicking the blue bar with the same label. You must map the input parameters defined in the Input tab of this dialog to the trigger output parameters. This mapping must be done in the trigger. The mapping creates a contract between the trigger and the flow. This contract is mandatory, since the flow and the trigger were developed independent of each other and must now interact with each other.

Follow these steps to create a trigger for a blank flow:

    The Add a trigger dialog opens with available triggers displayed.

  3. Click the trigger icon to configure the trigger. Be sure to map the output of the trigger to the fields in the Input tab of the Flow Inputs & Outputs dialog.
  4. Optionally, add additional triggers by clicking the icon and following the steps above.
