// The version number (9_5_0) should match version of the Chilkat extension used, omitting the micro-version number.
// For example, if using Chilkat v9.5.0.48, then include as shown here:
include("chilkat_9_5_0.php");

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

// Sends the following PUT request:
// PUT https://marketplace.walmartapis.com/v2/inventory?sku={SKU}

$sbUrl = new CkStringBuilder();
$success = $sbUrl->Append('https://marketplace.walmartapis.com/v2/inventory?sku={SKU}');

// First we need to generate a signature for our request.
// The signature needs to be re-generated for each new Walmart HTTP request.

// header fields: WM_SEC.AUTH_SIGNATURE, WM_SEC.TIMESTAMP, and WM_QOS.CORRELATION_ID

// Note: Do not explicitly set the "Host" header.  Chilkat will set it automatically.

// The body of the PUT request will be XML that looks like this:

// 	<?xml version="1.0" encoding="utf-8" ?>

// Build the XML request body:
