Question

If I define a GET operation as follows:

 [OperationContract]
 [WebInvoke(UriTemplate = "/findcategories", Method = "GET", RequestFormat = WebMessageFormat.Json, ResponseFormat = WebMessageFormat.Json)]
 FindCategoriesResponse FindCategories(FindCategoriesRequest request);

but when I try this I get the exception:

Operation 'FindCategories' in contract 'IComplaintService' uses GET, but also has body parameter 'request'. GET operations cannot have a body. Either make the parameter 'request' a UriTemplate parameter, or switch from WebGetAttribute to WebInvokeAttribute.

Is there no way of accepting a JSON object as a parameter when doing GET request?

Thanks

Nope. With a GET request you use query string parameters. If you want to send an entire JSON object you should use POST.
