Basket API not work

[Cary]

Hi,

I write an application using C#, I am encountering using basket API,
below is the code I wrote, please help me to figure out where the
problem is, thanks.

JsonObject jsonObject = new JsonObject();
jsonObject.Add("id",
JsonValue.CreateNumberValue(Convert.ToDouble(item.UniqueId)));
jsonObject.Add("amount", JsonValue.CreateNumberValue(25));
String jsonString = jsonObject.Stringify();
HttpWebRequest request = HttpWebRequest.Create("http://
www.kiva.org/basket/set") as HttpWebRequest;
request.Method = "POST";
request.ContentType = "application/json";
Stream dataStream = await request.GetRequestStreamAsync();
StreamWriter writer = new StreamWriter(dataStream);
await writer.WriteAsync(jsonString);
writer.Dispose();

after above code finished, I will open the IE to let the app user
browse the loans they chose, and check out through IE. below is code
of open IE.

await Windows.System.Launcher.LaunchUriAsync(new
Uri("http://www.kiva.org/basket"));

I'm not really sure I understand what you are trying to accomplish, but granted I'm pretty limited with my C#. 

Could you explain in pseudo-code what you are trying to do? 

Is your goal to send people to the Kiva basket with a POST request to fill in the loans to acquire?

You have to set a "loans" or "donation" POST parameter for the basket/set url to work.  If you don't, it will give you a 404.

I have add the loans to the structure, but still get 404 error, please

[Paul Ericksen]

This works:

<form method="post" action="http://www.kiva.org/basket/set" id="jsonform" > 

  <input name="loans" value='[{"amount":25,"id":420585},{"amount":25,"id":420586}]' type="hidden" /> 

  <input name="donation" value="0.00" type="hidden"/> 

  <input name="app_id" value="org.kivabank" type="hidden" /> 

  <input type="submit" value="Transfer loans to Kiva's basket" />

</form> 

I believe it only works for form posts.

Sent from my computer. No excuses for misspellings or missing words.

[Noah Balmer]

Here's a POST HTTP stream that I got when submitting Paul's working form in Firefox.  You want a body on your POST request that looks about like this.

And the response - a redirect to the basket page with appropriate basket contents:
