The following steps allow you to have the cart/checkout automatically select the first shipping rate from the options returned after a customer enters their shipping address.

1. Go to this page and copy the code you see there to your computer's clipboard.
2. Go to the “configuration” section of your Foxy store admin. Here's a link to that area.
3. Enable the “Add custom header and footer code to your templates” option if it isn't already, and paste the code into the “custom footer” textarea that appears within it.
4. Scroll down until you see the “Update” button and click to save.
5. Run a test by adding some of your shippable products to the cart and enter a shipping address to ensure that it works as expected.
