I am new to SharePoint but not having any luck. Please correct me if I am wrong on the process so far.

I am using react and need to create a CRUD app in react for SharePoint, so to do this I need to register the app with this link https://yourtenantname.sharepoint.com/_layouts/15/appregnew.aspx and then when I want to send a rest request I send the token I just created. Have tried connecting but getting a 403 error.

Just confused with the process of linking my react app with SharePoint folder recieving and sending data.

Any sugestions would help or articles.

  • If you are using React, I would look into using the SharePoint Framework (SPFx) instead. It's basically built on top of React, so you will be in familiar territory. Some starter articles here and here. Jul 12 '21 at 22:12
  • @user98224 Is your SharePoint site modern site if yes SPFx is the way. If no, then there's another way

You are missing an important step if your question actually represents the steps you’re taking.

After you register the app and acquire the Client ID & Client Secret, you need to grant the app permissions from the SharePoint Admin console. Use the GUI, not PowerShell - it’s a lot less typing and only requires a couple clicks.

See Microsoft article here. It gives a nice walk through of how to perform all the steps. This article has been my go-to when implementing tenant-wide apps - which is infrequent.

Caveat: the app will have complete God access (i.e.: SharePoint Administrator access), so craft your application taking this into account.
