tracker.write(event="logged_in", user_id="alice")
tracker.write(event="navigation", user_id="bob", metadata={"to": "dashboard"})
tracker.write(event="invoice", metadata={"details": {"amount": 1214, "from": "Ardbeg"}})
tracker.write(event="invoice", metadata={"details": {"amount": 123, "from": "Lagavulin"}})
