A Journal about the experiences I have developing little applications in C#, Perl, Html and Javascript and talking about things new things that I use. Always Geeky; Always Nerdy; Always poor Grammer!

I am a Software Analyst Developer working in Southport, England but living in Liverpool. I develop mainly in C# and ASP.Net. I have been developing comercial software for several years now. I maintain this site (hosted at SwitchMedia UK) as a way of exploring new technologies (such as AJAX) and just generally talking about techie geek issues. This site is developed through a host of Perl scripts and a liberal use of Javascript. I enjoy experimenting with new technologies and anything that I make I host here.

Google Search: ebay asp.net api soap wsdl [part deux]

Just following on from one of my previous post about using SOAP requests from ASP.Net to access Ebay.

I have finally worked out [it wasn't hard in the end] how to do it.

A few things that I had problems with were:
  • Most of the request REQUIRE the version attribute to be set
  • The DetailLevel attribute must be set on some request to enable you to
  • A Authentication Token is required to send request to Ebay. The Authentication token is used so that the user doesn't need to give their user name and password credentials away to the program. The auth token seems to be a cryptographic hash.
  • If you are using the WSDL url, you must also provide query string parameters so that Ebay know what to do with the request. [http://developer.ebay.com/DevZone/SOAP/docs/WebHelp/wwhelp/wwhimpl/js/html/wwhelp.htm]

The Code Follows:


Ebay.eBayAPIInterfaceService service = new Ebay.eBayAPIInterfaceService();
string appId = "APPID"; // use your app ID
string devId = "DEVID"; // use your dev ID
string certId = "CERTID"; // use your cert ID
string endpoint = "https://api.sandbox.ebay.com/wsapi";
string callName = "GetSearchResults";
string siteId = "0";

string version = "437";
// Build the request URL
string requestURL = endpoint
+ "?callname=" + callName
+ "&siteid=" + siteId
+ "&appid=" + appId
+ "&version=" + version
+ "&routing=default";
// Create the service

// Assign the request URL to the service locator.
service.Url = requestURL; //"https://api.sandbox.ebay.com/wsapi";
// Set credentials
service.RequesterCredentials = new Ebay.CustomSecurityHeaderType();

service.RequesterCredentials.eBayAuthToken = "MY_TOKEN"; // use your token
service.RequesterCredentials.Credentials = new Ebay.UserIdPasswordType();

service.RequesterCredentials.Credentials.AppId = appId;
service.RequesterCredentials.Credentials.DevId = devId;
service.RequesterCredentials.Credentials.AuthCert = certId;

Ebay.GetSearchResultsRequestType req = new Ebay.GetSearchResultsRequestType();

req.Query = "SSX";
req.DetailLevel = new Ebay_Test.com.ebay.developer.DetailLevelCodeType[1];
req.DetailLevel[0] = Ebay.DetailLevelCodeType.ReturnAll;

req.Version = version;

Ebay.GetSearchResultsResponseType resp = service.GetSearchResults(req);
//Do some more stuff
