Lua Requires Chilkat v9.5.0.97+

OneDrive with OAuth2 Client Credentials

See more OneDrive Examples

Demonstrates how to authenticate with Microsoft OneDrive using OAuth2 client credentials. This example provides the client ID, client secret, and tenant ID to Chilkat, and internally Chilkat will fetch the OAuth2 access token via client credentials as necessary. Therefore, it is not necessary for the application to explicitly fetch the OAuth2 access token beforehand. Lua

-- This example requires the Chilkat API to have been previously unlocked.
-- See Global Unlock Sample for sample code.

-- You'll need to have registered an app in Azure beforehand.
-- See How to Create an Azure App Registration for OAuth 2.0 Client Credentials

-- Note: For OneDrive, your registered app needs one or more of these permissions:  Files.Read.All, Files.ReadWrite.All, Sites.Read.All, Sites.ReadWrite.All
