(Visual Basic 6.0) Walmart - Get List of Orders

Demonstrates how to get a list of all orders.

Note: This example requires Chilkat v9.5.0.67 or greater.

Chilkat ActiveX Downloads

ActiveX for 32-bit and 64-bit Windows

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

' Demonstrates how to get a list of Walmart orders and parse the XML result.

' ---
' Note: The Walmart documentation indicates that the createdStartDate/createdEndDate query parameters are optional,
' however, this may not actually be the case.  It may be that at least one is required for getting a list of orders.
' ---

' The general format to get orders is as follows:
' GET https://marketplace.walmartapis.com/v3/orders?sku={sku}&customerOrderId={customerOrderId}&purchaseOrderId={purchaseOrderId}&status={status}&createdStartDate={createdStartDate}&createdEndDate={createdEndDate}&fromExpectedShipDate={fromExpectedShipDate}&toExpectedShipDate={toExpectedShipDate}&limit={limit}

Dim sbUrl As New ChilkatStringBuilder

' We'll just get 2 results so we can demonstrate iterating over the XML..
Dim numReplaced As Long
numReplaced = sbUrl.ReplaceI("{limit}",2)

' Get the current system date/time and add -7 days to get 1 week ago.
Dim dtStartDate As New CkDateTime
