Send request at the checkout to update shipping options

I have a client with a Plus store. They want to offer a same day delivery option in specific area's.

To do this, it requires a request to an external API with the customers shipping post code to see if the same day option is available to them. If it is, the available shipping options should be updated.


Is there any way to do this?

Hey @Appifiny,


The CarrierServices API sounds like the way to go.


Alternatively, you could maintain a list of postcodes and use Shopify Scripts to hide/show options based on shipping postcode.
