Distance Based Shipping Integration Index
Set up for RMS
RMS is special in that you can set up shipping at your POS. To make this work for distance based shipping you need to set up a shipping method based on weight. However, where you would normally enter weight values, enter distances instead. The second column, where you enter costs doesn't change.
Once you have this set up in RMS, sync to your store. The new shipping method should appear in the WSM Shipping & Taxes interface. Add your new shipping method to the country you wish it to be available in.
Now click the Change link beside Shipping Integration and a modal window will pop up.
The Shipping Carrier should be set to Charge by distance
The Shipping Service should be set to Calculate distance using Google API
Your new shipping method should now be available in your store checkout!
