Attaching a Flow to One or More Triggers
If you have created a blank flow without attaching it to a trigger, you can now attach it to an existing trigger that is being used by another flow in the same app.
A flow that is created without being attached to a trigger has its input and output parameters defined on the Flow Inputs & Outputs tab. You can access it by clicking the blue bar with the same label. The output from the trigger is the input to the flow. So, you must map the input parameters defined on 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 and is mandatory for the flow and the trigger to interact with each other.
You can use one of these methods to attach a flow to a trigger:
- From the flow details page:
- Open the flow details page by clicking the flow name on the app details page.
- From the Triggers palette, drag a desired trigger to the trigger's area.
For REST, you are prompted to enter additional handler setting details.
Click the trigger icon to configure the trigger as needed. For REST triggers, be sure to map the trigger outputs to flow inputs and the flow outputs to the trigger reply.
