(PowerBuilder) SharePoint OAuth2 Client Credentials Authentication

See more SharePoint Online Examples

Demonstrates 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.
