Tradera Developer Program

The API supports caching for certain methods. Right now those are:

• GetSearchResult
• GetSearchResultAdvanced
• GetSearchResultAdvancedXml

To enable caching for a method call, the parameter maxResultAge needs be specified, either on the query string or in a SOAP header.

GetSearchResult with caching, using the query string

01: [STAThread]
02: static void Main(string[] args) {
03: 
04: 	try {
05: 		string appId = "yourAppId"; // Use your application Id
06: 		string appServiceKey = "yourAppServiceKey"; // Use your application service key
07: 
08: 		Tradera.Api.PublicService publicService = new Tradera.Api.PublicService();
09: 
10: 		publicService.Url += string.Format("?appId={0}&appKey={1}", appId, appServiceKey);
11: 
12: 		// Allow results that has been cached for a maximum of 60 seconds.
13: 		publicService.Url += "&maxResultAge=60";
14: 
15: 		Tradera.Api.SearchResult searchResult = publicService.GetSearchResult("ipod", 0, 1,
16: 			Tradera.Api.SearchOrderBy.EndDateAscending);
17: 		
18: 		Console.WriteLine("Number of items returned: {0} Total: {1}",
19: 			searchResult.Items.Length, searchResult.TotalNumberOfItems);
20: 
21: 		searchResult = publicService.GetSearchResult("ipod", 0, 1, 
22: 			Tradera.Api.SearchOrderBy.EndDateAscending);
23: 			  
24: 		Console.WriteLine("Number of items returned (cached): {0} Total: {1}",
25: 			searchResult.Items.Length, searchResult.TotalNumberOfItems);
26: 
27: 		Console.ReadLine();
28: 
29: 	} catch(Exception exception) {
30: 
31: 		Console.WriteLine("Error: {0}", exception.Message);
32: 		Console.WriteLine(exception.StackTrace);
33: 		Console.ReadLine();
34: 	}
35: }

Remarks

• Add your application Id and application service key on lines 5 and 6.
• Use the name you gave your web reference in place of the Tradera.Api prefix used in lines 8, 15, 16 and 22.

10: 		publicService.AuthenticationHeaderValue = new Tradera.Api.AuthenticationHeader();
11: 		publicService.AuthenticationHeaderValue.AppId = appId;
12: 		publicService.AuthenticationHeaderValue.AppKey = appServiceKey;
13: 
14: 		publicService.ConfigurationHeaderValue = new Tradera.Api.ConfigurationHeader();
15: 
16: 		// Allow results that has been cached for a maximum of 60 seconds.
17: 		publicService.ConfigurationHeaderValue.MaxResultAge = 60;
