(Delphi DLL) Walmart - Get a FeedItem's Status

Note: This example uses classes, properties, or methods discontinued in Chilkat v11.0.0 or greater.

Note: This is an older example for the Walmart v2 API. You should instead use the Walmart v3 API.

Demonstrates how to get a Walmart feedItem's status.
