The add_shipping_info event is a intermediate checkout-funnel event located between begin_checkout and add_payment_info. It is common to send when you click the 'Next' button after entering the delivery address or selecting the delivery method (regular delivery, same-day delivery, etc.).
The shipping_tier parameter allows you to record the selected shipping method (e.g. 'Ground', 'Air', 'Next-day'). Through this, you can compare the selection rate and final purchase conversion rate by delivery method. If you also send the items array, value, currency, and coupon, you can record the shopping cart configuration at that stage.
In the case of clients using multi-step checkout forms in weballin practice, a GTM trigger is placed on the 'Next' button of each step to send add_shipping_info and add_payment_info in order. In the case of single-page checkout (SPA checkout), the implementation method of detecting transitions between steps can be complicated, so cooperation with the development team is essential.
