WebApi Post goes to Get method

Question

In my WebApi I'm trying to add a POST method. I have the GET already working. With the addition of the POST method every HTTP POST url I try goes to the GetByCatalog method. How can I fix this? Probably a routing issue but I can't manage to fix it.

Edit:

I'm using the NuGet Package WebAPITestClient now to do the request it works perfect after the suggested modifications of atornblad

Answer 1

The URL you posted at the end hints that you are not actually using POST to make the request, but actually GET . You should NOT include the /Post in the url. The Web API infrastructure takes care of that for you if you do a POST to http://localhost:56909/api/customer instead! All the values passed in the URL should actually be passed as POST data, and not as query string values, and you really should remove the [FromUri] attribute.

I do not know what framework (if any) you are using to make the request from the browser, but please make sure you are POST -ing and not GET -ting.

IF you are using jQuery, take a look at how to correctly perform a POST request here: http://api.jquery.com/jquery.post/

Otherwise, look at your framework's documentation. Also, if you edit your post to include the client-side code (JavaScript) , I could update this answer to be more in line with your conditions.
