Re: forms delete all responses
Use Send HTTP Request to SharePoint Connector in Power Automate.
You need your TenantID, UserID and FormID(s).
See Azure Active Director or Powershell to get Tenant and UserIDs. The form URL shows the ID.
My flow deletes all responses from many forms each night.
I created a simple array FormID with Name & ID of all the forms. You could easily use a MS List or excel or whatever source you want to maintain for Form Name/IDs.
Loop the array and delete all responses.
You Parse the JSON (your array) inside the loop to be able to use the ID string variable in the HTTP connector. Makes it easy to read and understand the flow, I just prefer to an expression.
