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 send a Walmart REST API request to get all feed statuses.

    -- --------------------------------------------------------------------
    -- 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.
