// 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}

Chilkat.StringBuilder sbUrl = new Chilkat.StringBuilder();
bool success = sbUrl.Append("https://marketplace.walmartapis.com/v2/inventory?sku={SKU}");
int numReplaced = sbUrl.Replace("{SKU}","HOPP~904~51041");

string requestMethod = "PUT";

// First we need to generate a signature for our request.
// The signature needs to be re-generated for each new Walmart HTTP request.
Chilkat.AuthUtil authUtil = new Chilkat.AuthUtil();

string wmConsumerId = "WALMART_CONSUMER_ID";
string wmPrivateKey = "WALMART_PRIVATE_KEY";
string jsonStr = authUtil.WalmartSignature(sbUrl.GetAsString(),wmConsumerId,wmPrivateKey,requestMethod);
if (authUtil.LastMethodSuccess != true) {
    Debug.WriteLine(authUtil.LastErrorText);
    return;
}

// The JSON returned by WalmartSignature contains the values to be used in the following
// header fields: WM_SEC.AUTH_SIGNATURE, WM_SEC.TIMESTAMP, and WM_QOS.CORRELATION_ID
Chilkat.JsonObject json = new Chilkat.JsonObject();
json.Load(jsonStr);

Chilkat.Http http = new Chilkat.Http();
http.SetRequestHeader("WM_SVC.NAME","Walmart Marketplace");
http.SetRequestHeader("WM_QOS.CORRELATION_ID",json.StringOf("correlation_id"));
http.SetRequestHeader("WM_SEC.TIMESTAMP",json.StringOf("timestamp"));
http.SetRequestHeader("WM_SEC.AUTH_SIGNATURE",json.StringOf("signature"));
http.SetRequestHeader("WM_CONSUMER.ID",wmConsumerId);
http.Accept = "application/xml";

// 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" ?>
// 	<wm:inventory xmlns:wm="http://walmart.com/">
// 	    <wm:sku>HOPP~904~51041</wm:sku>
// 	    <wm:quantity>
// 	        <wm:unit>EACH</wm:unit>
// 	        <wm:amount>235</wm:amount>
// 	    </wm:quantity>
// 	    <wm:fulfillmentLagTime>5</wm:fulfillmentLagTime>
// 	</wm:inventory>

// Build the XML request body:
int originalAmount = 234;

Chilkat.Xml xmlBody = new Chilkat.Xml();
xmlBody.Tag = "wm:inventory";
xmlBody.AddAttribute("xmlns:wm","http://walmart.com/");
xmlBody.UpdateChildContent("wm:sku","HOPP~904~51041");
xmlBody.UpdateChildContent("wm:quantity|wm:unit","EACH");
xmlBody.UpdateChildContentInt("wm:quantity|wm:amount",originalAmount + 1);
xmlBody.UpdateChildContent("wm:fulfillmentLagTime","5");

Debug.WriteLine("PUT request body:");
Debug.WriteLine(xmlBody.GetXml());
Debug.WriteLine("--");

// This is a simple PUT that can be sent w/ the PutText method.
string xmlStr = await http.PutTextAsync(sbUrl.GetAsString(),xmlBody.GetXml(),"utf-8","application/xml",false,false);
if (http.LastMethodSuccess != true) {
    Debug.WriteLine(http.LastErrorText);
    return;
}

Chilkat.Xml xml = new Chilkat.Xml();
xml.LoadXml(xmlStr);

// A successful response should have a 200 response status

    Debug.WriteLine(xml.GetXml());
    Debug.WriteLine("Response Status Code: " + Convert.ToString(http.LastStatus));
    Debug.WriteLine("Failed.");
