Update shipping methods from back-end after filling shipping details at checkout step #2

[tniezg]

What is the motivation for adding / enhancing this feature?

Currently, the request to cart.shippingmethods_endpoint (defined in VS's config file) depends on cart.synchronize and is made before the user has a chance to enter full shipping details. The request contains only country_id (ex. 'US') which for some stores may not be enough to determine shipping methods available for the order and to calculate its total price. Storing all shipping methods locally inside VS's config file is also not an option.

I'm looking for a new option inside VS's config file, such as cart.synchronizeShippingMethodsAfterShippingDetails which will defer requesting available shipping methods to after user enters full shipping details.

What are the acceptance criteria

• New option in configuration for VS which defers fetching shipping methods.
• Shipping methods are fetched after shipping details are filled.
• The request for shipping methods contains all shipping details instead of only country_id.
• Shipping methods are fetched again when shipping details change.

Can you complete this feature request by yourself?

NO
