Yes. Every account has two kinds of key:
lk_test_keys work on test staging areas only. Use them while you build. Test staging areas are made up: no vehicles stand in them, and they are your account's alone. They work just as real ones do.lk_live_keys book real spots.
Both call the same address, https://api.golanoo.com/v1. The key you send decides which you get. More in the API overview.
