Hello.

This post is a follow-up to my earlier one about using SOAP requests in ASP.Net to access the eBay API. I've finally figured out how to make it work! A few key things to note: most requests need the "version" attribute, some require the "DetailLevel" attribute, and you'll need an eBay Authentication Token (a cryptographic hash) for security. When using the WSDL URL, remember to include query string parameters so eBay knows what to do. I've included some sample C# code demonstrating how to build the request URL, set credentials, and handle the response.

I'm exploring the eBay API using ASP.NET and SOAP. It's proving a bit cumbersome due to its monolithic structure. Ideally, each API call would have its own WSDL and SOAP interface for easier management. Currently, I'm stuck on generating a User Token for authentication, having tried my developer account, regular eBay account, and a new account without success. Any advice on obtaining a User Token would be greatly appreciated!
