(Unicode C) Docusign Refresh OAuth2 Access Token

Demonstrates how to refresh a Docusign OAuth2 access token. The refresh does not require user interaction via a web browser. If an access token expires (typically with a 401 response code), a new access token can be automatically obtained by using the code in this example.

For more information, see https://developers.docusign.com/esign-rest-api/guides/authentication/oauth2-code-grant
