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

// We demonstrated how to get an access token for your Azure Key Vault
// in this example: Azure Key Vault Get OAuth2 Access Token using Client Credentials

// However.. starting in Chilkat v9.5.0.96, instead of directly providing Chilkat with the OAuth2 access token,
// you can instead provide the means for Chilkat to automatically get the OAuth2 access token,
// and in addition, Chilkat will automatically re-fetch a new OAuth2 access token as needed, such as shortly 
// prior to or after expiration.

// You do this by setting the AuthToken property to a JSON string that contains the required information.

loJson = createobject("CkJsonObject")

// The APP_PASSWORD is the "password" returned by the Azure CLI command: az ad sp create-for-rbac --name http://example.com --role Contributor
// See Azure Key Vault Get OAuth2 Access Token using Client Credentials
loJson.UpdateString("client_secret","APP_PASSWORD")

// The access token will be for Azure Key Vault operations.
loJson.UpdateString("resource","https://vault.azure.net")

// Specify the token endpoint which includes your tenant ID.
loJson.UpdateString("token_endpoint","https://login.microsoftonline.com/TENANT_ID/oauth2/token")

// Instead of providing an actual access token, we give Chilkat the information that allows it to 
// automatically fetch the access token using the OAuth2 client credentials flow.
