How do I fetch a LINE user profile?
Short answer: You can get line user profile in LINE by hand from its own interface, but it won’t repeat itself. On TinyCommand, add the LINE Get LINE User Profile action to a workflow, map its 1 input from any upstream app, and it runs automatically every time the trigger fires. No code, and a free tier to start.
