A. Example: Fetch User Details from SharePoint

1. Create a Flow → Use PowerApps trigger.
2. Add “Get Items” (SharePoint List action).
3. Add “Respond to PowerApps” and select SharePoint data fields to return.

📌 Example Flow Output (JSON)

{
  "FullName": "John Doe",
  "Email": "johndoe@example.com"
}

B. Power Apps Formula to Fetch Data

Set(userData, GetUserDetailsFlow.Run("EmployeeID123"))

🔥 The userData variable now holds the API response!
