404 Response with Retrofit POST request with Headers parameters

Question

I am new to Retrofit Library. When I sending post request with headers parameters using hashMap using @HeaderMap annotation.

Below is my code

 @POST(Constants.UrlPath.POST_CLOSE_EVENT)
Call<ResponseBody> callDeleteEventRequest(@HeaderMap Map <String, String>id);

I am sending the headers using HashMap here like this.

 HashMap<String, String> headers = new HashMap<>();
                 headers.put("eventId", String.valueOf(1));

I am getting 404 error response. Please some one help me. I have reviewed some Stack Overflow links, but again I am getting this error.

Answer 1

Try this:

@FormUrlEncoded
@POST(Constants.UrlPath.POST_CLOSE_EVENT)
Call<ResponseBody> callDeleteEventRequest(@FieldMap Map <String, String>id);

Answer 2

add headers in your interface class:

 @Headers({"Content-Type: application/json",
        "eventId: 1"})
@POST(Constants.UrlPath.POST_CLOSE_EVENT)
Call<ResponseBody> callDeleteEventRequest();

Answer 3

check your path Constants.UrlPath.POST_CLOSE_EVENT is right or not. try to call using postman if it is working fine in that or not.
