Hi,

I get an error when I follow the guide to use the Forms APi to access question details:

Get Question details of Forms with Power Automate - MoreBeerMorePower

Is there an API to read Microsoft forms data | Microsoft Community Hub

Automate MS Forms with Power Automate - Hacking the Forms API

Looking at the network in developer tools when submitting a form is this:

https://forms.office.com/formapi/api/5e0f21a6-60fe-4adb-9df4-517db39f54ba/groups/0184ea8b-c9c3-4f7f-bf03-44e71ba1a145/forms('piEPXv5g20qd9FF9s59UuovqhAHDyX9PvwNE5xuhoUVUMklIOVFYOTNYWjdPT1RQTlZLOE8wSDk4VyQlQCN0PWcu')/responses

Error I get is:

{

"status": 400,

"message": "SharePoint Site Address 'https://forms.office.com/' is not valid\r\nclientRequestId: 05b23999-b72f-48d4-aa54-51c37fa48733",

@Nived_Nambiar Yes I also tried /responses. I believe I have copied the exact way shown in that blog. Do you get it to work with a Form in a group?
