We are a domestic and international shipping provider in Sri Lanka and we have developed location and delivery time based cost calculator API (along with creating shipping labels, tracking) for our clients who use woocommerce already. We are looking forward to setup same for clients who use shopify to automate their fulfilment process.
We do have a list of districts (same as states) and cities under them along with their postal codes (retrieved from the department of postal) for rate calculation if shopify needs update their system with same as well.
Could someone assist us on setting this up.
Thanks in advance.
