Add-In Permissions in SharePoint Online

http://sharepoint/content/sitecollection/web	FullControl
http://sharepoint/content/sitecollection/web/list	FullControl

After you have registered the custom app, configure the tenant permissions on the custom app.

To configure the tenant permissions:

1. Launch the SharePoint Admin Center using the URL: https://<your-tenant>-admin.sharepoint.com/_layouts/15/AppInv.aspx

   In the case of Multi-Geo tenants, for sites in a specific region (e.g., 'eur' for Europe), the URL for the SharePoint Admin Center changes accordingly. For instance, the URL for the domain abcdef and the region eur would be:
   https://abcdefeur-admin.sharepoint.com/_layouts/15/AppInv.aspx

2. In the SharePoint Admin Center, log in as the tenant admin.

3. In the App ID and Title section, perform the following:

   1. In the App Id field, enter the AppID of the custom app you have created and click Lookup to search for the custom app.

   2. In the App Domain field, enter www.localhost.com as the app domain.

      Do not enter any other string other than www.localhost.com in the App Domain field.

   3. In the Redirect URL field, enter https://localhost.com/ as the redirect URL.

      Do not enter any other URL other than https://localhost.com/ in the Redirect URL field.

   4. In the Permission Request XML field, enter the following values:

      <AppPermissionRequests AllowAppOnlyPolicy="true">
      <AppPermissionRequest Scope="http://sharepoint/content/tenant" Right="FullControl" />
      <AppPermissionRequest Scope="http://sharepoint/content/sitecollection" Right="FullControl" />
      <AppPermissionRequest Scope="http://sharepoint/content/sitecollection/web" Right="FullControl" />
      <AppPermissionRequest Scope="http://sharepoint/content/sitecollection/web/list" Right="FullControl" />
      <AppPermissionRequest Scope="http://sharepoint/taxonomy" Right="Read,Write" />
      </AppPermissionRequests>
