Just starting to work with SharePoint and Microsoft authentication and trying to get a SharePoint List into a JavaScript App. From Microsoft documentation, I need to use the following:
GET https://{site_url}/_api/web/lists/GetByTitle('List Title')
Authorization: "Bearer " + accessToken
Accept: "application/json;odata=verbose"
Have searched everywhere to find an definitive answer to how to obtain this accessToken. All the documentation I can find from Microsoft seem to be out of date. Does anyone know the current method to obtain an accessToken?
You use the POST operation on the api/get_token element to request your unique token that is required to authenticate the REST API requests. , and click Profile. Then, click Show token.
You could refer to this article to get access token:
