MS Forms automatic deletion of responses

Hi Forum,

I have a Forms survey that we use weekly for collecting data of how many employees are going to be eating inhouse the next week, so that out kitchen can make the correct portions.

This is a weekly thing, so i want to automate that the Forms data is being deleted at the end of the week, so people can click and paste a response again (i have currently set the survey to be answered once only)

Is this possible? I dont see that Forms itself supports this, so im thinking it can be solved with a power automate flow of some sort.

Make sure you replace the <tenant>, <userid> and <formid> by guid values. Also remove the '<' and '>' characters as well.

So, the format of the link should look like the below example (I used some random ids).

https://forms.office.com/formapi/api/5a5206d8-7b04-4c43-befb-aa25379245b1/users/fe8b03e6-e7dd-4749-b7cb-2715a18736e8/forms('HSEvendXekKorjpArMPzywSAKiQEb4BLkzEWYcY_6jRUQUpSVFJOVktEUE9RSTdaNVVJUjdPMDlTTy4u')/responses

In my example I used a environment variable/parameter the tenant id, a dynamic content field from the Get My Profile (v2) for the user id and string variable called Form Id (Initialize variable action) for the form id.

The tenant id can be retrieved via this website or in Entra Id for example:

https://www.whatismytenantid.com/

The form id can be found in the address bar when editing the form. The user id (if you created the form) can be retrieved via the get my profile (v2) action.

Hi @Expiscornovus

I have tried to follow your steps but i reach an issue with the FormID part for some reason.

I have setup the "initialize variable" to use "string" and then paste the FormID in.

When i run the flow it keeps giving me the following error: Action 'Invoke_an_HTTP_request' failed: Invalid form id. Inner Message: Invalid form id

(For security reasons, i have not posted the form id that is linked to the document)

Can you see what im doing wrong?

Yes, this would be possible. You can use the Forms API for this.

Below is an example for a personal form (which you created yourself).

Use an Invoke an HTTP request (preauthorized action). Make sure you use the below for the connection settings

2. In the action use the DELETE method and the below URI format

https://forms.office.com/formapi/api/<tenantid>/users/<userid>/forms('<formid>')/responses

For your requirement, it is impossible, you could not operate Forms from power automate like delete response or create new forms.

For a workaround, you could try below:

Add new filed like target week to indicate which week want to eat in the Form

Try When a new response is submitted Power Automate Trigger to save the User response to Excel file

Count the user numbers in Excel
