>Hi,

>I am attempting to learn how to use a Web API (created by another party) can be used in an ASP.NET application. I have used this Web API in a VFP application. In summary this is what I do in VFP application:
>1. Create a JSON with IDs and value pairs (that need to be passed to the Web API)
>2. Create a wwHTTP object, based on the West-Wind wwHTTP.PRG
>3. Call httpget or httppost method of the wwHTTP object and pass the end point of the Web API
>4. Check Response string returned by the httpget, which tell the app if successful or not
>
>Would the steps in the ASP.NET application be the same? And if yes, how would I create a HTTP object (step 2 above) in the ASP.NET application? Does .NET have a namespace/class for that?
>
>TIA for any input or suggestions

You can just use HttpClient with PostAsJsonAsync or GetAsync/ReadAsSync.

Simple example: https://docs.microsoft.com/en-us/aspnet/web-api/overview/advanced/calling-a-web-api-from-a-net-client
