Demonstrates how to get a LinkedIn OAuth2 access token from a desktop application or script.

Note: This example requires Chilkat v10.1.2 or later.

# which would look like "http://localhost:3017/"
# See a screenshot below...

# 4: Completed with Access Denied. The OAuth2 flow has completed, the background thread exited, and the error JSON is available in AccessTokenResponse property.
