eBay Shopping API for .NET?

Question

I've been looking around trying to find a .NET release of the eBay Shopping API. Is there any?

Answer 1

The link you provided states:

Supported Features

Formats: XML, SOAP, Name Value, JSON

Protocols: HTTP GET (REST) and POST"

It's a web service. You don't need a particular ".Net API". Just make a call to the webpage and handle the return value.

Example using information on this page

var xml = http://open.api.ebay.com/shopping?callname=FindProducts&responseencoding=XML&appid=YourAppId&siteid=0&QueryKeywords=harry%20potter&AvailableItemsOnly=true&MaxEntries=2&version=787
//parse the xml...

Of course you would need to use valid data. If you try using this as is you'll get an error xml response:

<FindProductsResponse xmlns="urn:ebay:apis:eBLBaseComponents">
        <Timestamp>2012-09-09T07:03:43.405Z</Timestamp>
        <Ack>Failure</Ack>
    <Errors>
        <ShortMessage>Application ID invalid.</ShortMessage>
        <LongMessage>Application ID invalid.</LongMessage>
        <ErrorCode>1.20</ErrorCode>
        <SeverityCode>Error</SeverityCode>
        <ErrorClassification>RequestError</ErrorClassification>
    </Errors>
    <Build>E789_CORE_BUNDLED_15285085_R1</Build>
    <Version>789</Version>
</FindProductsResponse>

However the whole point of this is that you send eBay some data via a query string and they return you xml.

This is the url used in the example above.
