Thank you for choosing Microsoft Power Platform Communities.
You're on the right track, and it's great that you're diving into Power Pages!
Here's how you can achieve your goal:
Generate and Display GUID After Form Submission:
Use Power Automate to create a flow triggered by the form submission in Power Pages.
In the flow, generate a GUID (if not already created) and store it in a Dataverse table along with the submitted data.
Return the GUID to Power Pages using the "Respond to PowerApps or flow" action in Power Automate. This action allows you to send data back to Power Pages, similar to how it works in Power Apps.
Display the GUID on the Submission Page:
After the form submission, configure the page to display the GUID returned by the flow. You can use JavaScript or Liquid templates in Power Pages to show the value dynamically.
Create a Search Page for GUID:
Add a new page in Power Pages where users can input the GUID.
Use a form or a search box to capture the GUID entered by the user.
Query the Dataverse table to fetch and display the details associated with the GUID. You can use Power Automate or a Web API call to retrieve the data.
