Adding sharepoint list's item without viewing permission

[kuchar71]

Hello. I need to build a powerapp to store employees' comments in sharepoint list. I prepared an app with a ms flow which update list with a new item. I want to permit apps's user to add new item to sharepoint list but I don't want to give them possibility to view this list. How can I do it?

@kuchar71 Without giving them access to the list, the only way you can do it is by creating a sub-flow.

Basically you set it up like this: The app calls a flow which then has an HTTP call to an endpoint of another flow.

In this second flow you will create the calls to SharePoint.

The first flow will be run as the user (with their permissions) who is currently using the app but the second flow will be run with the account of whoever created the flow (assuming yours) therefore you only need to allow that user access to the list and not anyone else.

If this answer is helpful then please consider marking it as a solution to help other users in the future.

Thanks for your help! I've done it in similar way, but your solution sounds even better.

My version is:
I have two flows. The first one adds an item into "temporary" list which is available for all app's user. The second one I made on admin's sharepoint account and it launches when new item in temporary list is created and it adds new item into "real" list (which is available for specific users) and then removes the item from temporary list.
