I am wondering how I specify "Standard Shipping (FedEx Ground or FedEx Home Delivery®)" as a shipping service using the eBay API. Can anyone provide any pointers? All of the samples just use the "Standard Shipping" option.
You need to specify FedExHomeDelivery. A table of shipping services for most eBay sites can be found here. Simply use the values in the ID for importing column for your eBay API calls.
As the types of shipping services change over time you may wish to periodically retrieve the latest services via the API as follows.
