I am creating a module in magento2. Currently my planning is when user will provide the shipping address detail and will click the next button, in back-end I will get the address given by the user , according to that I will send a api request to the shipping api, so that when user views the Reviews and payment section, I can show him/her when the product will be delivered.
But as per above plan, I am stuck at how to handle the next button click and getting the address input.
Please give some hints. So that I can proceed.
I have gone through the discussion in M2: Sending data by clicking Next on checkout. But Not getting any information.
Also searched in google. But no result.
