Trigger Power Automate Flows from Power Apps Code Apps (Full Tutorial)

Power Apps Code Apps just unlocked one of the most-requested capabilities: calling Power Automate cloud flows directly from your React code — with typed inputs, typed responses, and full IntelliSense.

In this full tutorial I walk through the entire workflow end-to-end, from the npm CLI commands to writing the React code that triggers the flow, passes parameters, and handles the response.

Then I take it further and showcase a full-fledged Help Desk code app that triggers a real approval workflow — so you can see exactly how this fits into a production-grade scenario.

⏱️ What you'll learn:
- How Power Automate integration works in Power Apps Code Apps
- Prerequisites: solution-aware flows + the PowerApps trigger
- Listing available flows with `npx power-apps list-flows`
- Adding a flow to your code app with `npx power-apps add-flow`
- What gets generated: TypeScript service classes, models, and more.
- Writing React code to call the flow's `Run` method
- Passing input parameters and handling the typed response
- Error handling with the success / data / error pattern
- Updating flows in your code app
- Help Desk app that triggers an approval workflow

🛠️ Tech stack:
- Power Apps Code Apps
- Power Automate (cloud flows)

- VS Code

⚠️ Important notes:
- Only flows using the PowerApps trigger are supported (no scheduled or automated flows)
- Flows must be solution-aware
- End users need the App Opener security role (or equivalent) in Dataverse
- Flow commands are only in the npm CLI — not pac code
