Recently I worked on one PowerApp which will call the MS Flow to perform my action. Initially, I created a Flow with 8 parameters and passing the values from PowerApp but at the end I realized that I can perform my action with 6 parameters in MS Flow, so decided to delete the extra 2 parameters as my PowerApp is expecting the value for those parameters which are not required. There is no direct approach to delete the parameters in Flow, I think Microsoft still working on this issue but there is workaround to do this
- Delete the PowerApp trigger on the top of the MS Flow and you see a message box “This step and associated dynamic content will be deleted from this flow.”
- Click on OK (It won’t affect the actions in your flow)
- Add the PowerApp trigger again, this should give you a chance to provide a new dynamic content.
I know it’s not a best approach but as of now we don’t have any better way to resolve this issue. Hope it helps….
