(C++) SharePoint OAuth2 Client Credentials AuthenticationSee more SharePoint Online ExamplesDemonstrates how to authenticate with OAuth 2.0 using the client credentials grant type. This is for SharePoint Online which is the cloud-based service provided by Microsoft as part of Office 365. (Users access SharePoint Online through a web browser, and the service is hosted on Microsoft's servers.) Note: This example uses the new "Integrated OAuth2 Client Credentials" feature introduced in Chilkat v9.5.0.96.
