# --------------------------------------------------------------------
# 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.
