Retrofit @DELETE json

Question

So I have only jsut started using Retrofit and trying to get my head around it. I have created a @POST:

String suuid = UUID.randomUUID().toString();

    String json = "{\"id\" : \""+suuid+ "\", \"sensorType\" : \"sound\", \"threshold\" : \"50\", \"operator\" : \">\", \"actuator\" : \"1\", \"actuatorAction\" : \"4\"}";
    RequestBody requestBody = RequestBody.create(MediaType.parse("application/json"),json);
    api.postTest(requestBody).enqueue(new Callback<ResponseBody>() {
        @Override
        public void onResponse(Call<ResponseBody> call, Response<ResponseBody> response) {

        }

        @Override
        public void onFailure(Call<ResponseBody> call, Throwable t) {

        }
    });

I then want to be able to delete the same data that was just sent as json. I tried using:

@DELETE("/TEST")
Call<ResponseBody> deleteTest(@Body RequestBody requestBody);

With this I simply changed the api.postTest to api.deleteTest and crashed the app? I cant use ID as each ID is using UUID. And server would hold multiple data entrys.

Any help is appreciated.

What's the implementation on the server side? What's the reply? If your app is crashing you need to post the stacktrace... — Joaquim Ley, Feb 13 '18 at 14:06
@RikhilShah you haven't shown anything about the server implementation so I can not help. But you can work with query parameters — gmetax, Feb 13 '18 at 15:21

Try this:

@HTTP(method = "DELETE", path = "/TEST", hasBody = true)
Call<ResponseBody> deleteTest(@Body RequestBody requestBody);

`path` is not mandatory if your first argument to interface method is a url annotated with @Url . Originally answered here : https://stackoverflow.com/a/62920127/8956093 – Ramakrishna Joshi Jul 15 '20 at 19:24
