I have created woocommerce plugin which gets shipping rates from third party URL(my web site) and displays it on the checkout page. when I click on one of shipping method it also calculates correct shipping rates, but when I again refresh checkout page my selected shipping option gets lost and I have to select again. also, my custom shipping option does not reach to order after a successful order.
In below Screenshot, I pass Suburb and Postcode, and I get all rates i desire, when i click on one of shipping method it also calculates correct a shipping rates
After Click on Place Order, it takes first shipping method which is a flat rate: $5, please see below screenshot
Here is my Plugin please have a look and guide me where I am going wrong.
