How to Find the Correct Microsoft Forms ID for Power Automate
Question details
The user needs to locate the exact Microsoft Forms ID to connect a form to a Power Automate flow, as using incorrect identifiers from other sharing links causes the flow to fail.

- Product
- Microsoft Forms
- Device & OS
- not provided
- Scenario
- Connecting a Microsoft Form to a Power Automate flow to automate response handling.
- Observed behavior
- Microsoft Forms displays different identifiers across the Collect Responses, Collaborate, and Duplicate links, creating confusion about which ID to use in Power Automate.
Ensure you are logged into your Microsoft 365 account with editing permissions for both the target Microsoft Form and the Power Automate flow.
Extract the Form ID from the Collect Responses Link
The correct Form ID for Power Automate is exclusively found in the Collect Responses link. Using this specific link ensures your flow connects properly.
Microsoft Forms generates different identifiers depending on the sharing context. Identifiers from 'Collaborate' or 'Duplicate' links will not work for API connections. You must extract the ID from the response collection link.
Navigate to Microsoft Forms and open the specific form you want to connect to Power Automate.
Click the 'Collect responses' button located at the top right corner of the screen.
Click the 'Copy link' button to save the form's URL to your clipboard.
Paste the copied link into a text editor. Locate the text string that comes immediately after 'id=' in the URL. This string is your correct Form ID.
Go to your Power Automate flow and paste this exact string into the 'Form Id' field of your Microsoft Forms trigger or action.

Frequently Asked Questions
Why did my Microsoft Form ID change suddenly?
Your Form ID remains constant unless the form's ownership changes. If you move a personal form to a Microsoft 365 Group, the underlying ID will regenerate, requiring you to update any connected Power Automate flows.
Can I use the ID from the Collaborate link in Power Automate?
No, the identifiers found in the Collaborate or Duplicate links are structurally different from the actual Form ID. You must always extract the ID from the 'Collect responses' link for use in Power Automate.
What happens if I use the wrong Form ID in Power Automate?
If an incorrect Form ID is entered, your flow will fail to trigger or will be unable to retrieve the submitted responses. This typically results in a connection error or a flow that silently fails to run.
Do I need to manually update the Form ID if I edit the form questions?
No. Editing the title, questions, or settings of the form does not change the Form ID. You only need to update the ID in Power Automate if the form is moved to a different group or account.
