How to send a HTTP-delete with a body in retrofit?

A more simplified answer.

@HTTP(method = "DELETE", path = "/api/analysis_delete", hasBody = true)
Call<Analysis_Delete_RequestResult_Api10> analysis_delete_api10(@Field("seq") String seq);

This will do the trick.

Here is my version

@HTTP(method = "DELETE", path = "{login}", hasBody = true)
Call<ResponseBody> getData(@Path("login") String postfix, @Body Map<String, Object> options);
