How to Open Classic Designer in Power Automate
Question details
The user needs to access the classic designer in Power Automate to edit a flow created in an older format.
- Product
- Power Automate
- Device & OS
- not provided
- Scenario
- Attempting to edit an older flow that displays an incompatibility warning or cannot be edited in the new Power Automate designer.
- Observed behavior
- The flow opens in the new designer by default, preventing edits to the older format unless the interface is switched back to the classic mode.
Ensure you are logged into your Power Automate account and have the direct URL of the specific flow you wish to edit open in your web browser.
Modify the Flow URL Parameter to Force Classic Mode
Change the URL parameter directly in your browser's address bar to request the classic designer interface.
Microsoft is transitioning users to the new Power Automate designer. However, you can temporarily force the classic designer to load by appending a specific query parameter to the flow's web address.
Navigate to Power Automate and open the flow you want to edit. Look at the full URL in your browser's address bar.
At the end of the URL, add or modify the parameter to read ?v3=false (for example: https://make.powerautomate.com/environments/Default-***/flows/***?v3=false).
Press Enter to reload the page with the modified URL. The classic designer should now load.
Looking for a Lightweight Alternative for Your Office Tasks?
While Power Automate handles complex background workflows, your everyday document, spreadsheet, and presentation tasks can be easily managed with WPS Office. It is a highly efficient, free alternative designed to streamline your daily work.
- 1. Download the Installer: Visit the official WPS Office website and download the free installer for your operating system.
- 2. Install WPS Office: Run the downloaded file and follow the simple on-screen instructions to set up the suite.
- 3. Open Your Files: Launch WPS Office and instantly open your existing Microsoft Office documents without formatting loss.
Frequently Asked Questions
Why does the URL keep switching back to v3=true?
Microsoft is actively phasing out the classic designer in favor of the new interface. Power Automate may automatically redirect the URL to enforce the use of the new designer (v3=true) for better feature compatibility.
Can I permanently set the classic designer as my default in Power Automate?
No, because the classic designer is being deprecated, there is no built-in setting to make it the permanent default. You must manually adjust the URL parameter or use the on-screen toggle if it is available for your specific flow.
Will my older flows break if I edit them in the new designer?
In most cases, no. Despite the warning that older formats might not be fully supported, you can usually ignore the alert and continue editing. The flow will typically save and function perfectly in the new environment.
