(PowerBuilder) Azure REST API Access Token

Demonstrates how to request an Azure REST API OAUTH2 access token.

Note: In order to access resources a Service Principal needs to be created in your Tenant. It is really convenient to do it via AZ CLI:

az ad sp create-for-rbac --name [APP_NAME] --password [CLIENT_SECRET]

// The result is an access token such as the following:

// We'll save this JSON to a file for other examples to use..
