How to get List items using clientid and client secret

Question

So, I have the Client ID and Client Secret for the SharePoint site. Using these, I am able to create the access token. However, when I use this access token to fetch list items, I receive an empty array, even though the SharePoint list contains values. The item count is displayed correctly, but I can't fetch the list values. What could be the issue here?

Answer 1

Per my test, I also received an empty array by using access token to fetch list items in the Postman. No specific content will be displayed by using this method, this is by design.

As a workaround, you can add SP REST JSON Extensions to google chrome. Then get results directly by using google chrome.

Here are results:
