Error: 401 'Microsoft.IdentityModel.Tokens.AudienceUriValidationFailedException' was thrown.

Question

I have used all the correct values here, and I'm receiving an access token from the code below

I have given this amount of API permission (for testing purposes ofcourse)

but when I access it through the endpoint below:
https://{site_url}.sharepoint.com/sites/TestSite/_api/web/GetFolderByServerRelativeUrl('/sites/TestSite/Shared%20Documents/Guide')/Files

I keep getting the error 401 'error_description': "Exception of type 'Microsoft.IdentityModel.Tokens.AudienceUriValidationFailedException' was thrown.

Why is it like this? Can anyone please help me regarding this issue?

Hi @Muhammad Arsal ,

1.Make sure your scope value is set to https://{tenant-name}.sharepoint.com/.default.

2.Build your REST API link, Here is an example of what the URL could look like:

https://mycompany.sharepoint.com/_api/web/GetFolderByServerRelativeUrl('Shared Documents/Target Folder')/Files
