// --------------------------------------------------------------------
// This example is for the older and deprecated Walmart v2 API.

// Use the v3 API instead: Walmart v3 Get All Feed Statuses

// This example requires the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

// Demonstrates how to send a request such as the following to get all feed statuses:
// Also demonstrates how to parse the results.
