Click on 
Click the 
button to manage your Shopify Store.
Under Checkout Rates Click 
Input Your Shopify Shared Secret - it is the same as the API Secret Key on your Shopify admin page.
Input some default dimensions. You can change these at any point so just use your most common or make one up!
Click 
Once connected your Shopify Store should now have Real-Time Rates enabled!
Once the above is completed you will want to make sure you go into your Products screen in your ShipTime account and edit/add weights for each of your products.
