Enter your Catch API Key so that CatchFeeder can connect to your Catch account to create listings and retrieve orders. If you haven't got an API key, you can enter some random numbers/letters to continue however through the set up and add it later in CatchFeeder under 'Settings - Catch - General'
Choose a default Shipping method for Catch. You can set up additional shipping options later if you need them. See Shipping Overview for more details on the options available.
