Trigger a SharePoint Online Action from another Application

Question

I have a use case where I would like to create a button in another application, that when clicked, will trigger a Flow or something, that will lead to the creation of a Folder in a specific document library in SharePoint.

Could such a use case be achieved with SharePoint Online and/or Flow?

Regards

Answer 1

You can use an HTTP Trigger for Flow that allows your application to trigger your flow using that address.

But, if you just want to create a folder in SharePoint from your application then CSOM is your friend. If your app is .NET then you can add PnP Core via NuGet and creating a folder should be pretty easy: https://www.nuget.org/packages/SharePointPnPCoreOnline

You can make similar calls via REST as well: https://docs.microsoft.com/en-us/sharepoint/dev/sp-add-ins/working-with-folders-and-files-with-rest

Answer 2

You can build a PowerApp and add button within it which will run the Microsoft Flow. (You can also embed the PowerApp within SharePoint page if you want).

You can create a new folder using Send an HTTP request to SharePoint in Microsoft Flow.

Below articles will help you to start with this:
