(SQL Server) OneDrive with OAuth2 Client Credentials

See more OneDrive Examples

Demonstrates how to authenticate with Microsoft OneDrive using OAuth2 client credentials. This example uses a new feature available starting in Chilkat v9.5.0.97, which is to provide the client ID, client secret, and tenant ID to Chilkat, and internally Chilkat will fetch OAuth2 access token via client credentials as necessary. Therefore, it is no longer necessary for the application to explicitly fetch the OAuth2 access token beforehand.

Note: This example requires Chilkat v9.5.0.97 or greater.
