Java Using OkHttp Library

OkHttpClient client = new OkHttpClient();

MediaType mediaType = MediaType.parse("application/json");
RequestBody body = RequestBody.create(mediaType, "{\"token\":\"c2a0b6221c5dd55ceb09ae1f74e46521756d\",\"priority \":0,\"application\":\"2\",\"sleep\":0,\"globalmessage\":\"\",\"globalmedia\":\"\",\"data\":[{\"number\":\"1212\",\"message\":\"Test\"}]}");
Request request = new Request.Builder()
  .url("https://pickyassist.com/app/api/v2/push")
  .post(body)
  .addHeader("content-type", "application/json")
  .build();

Response response = client.newCall(request).execute();

Java Using Unirest Library

HttpResponse<String> response = Unirest.post("https://pickyassist.com/app/api/v2/push")
  .header("content-type", "application/json")
  .body("{\"token\":\"c2a0b6221c5dd55ceb09ae1f74e46521756d\",\"priority \":0,\"application\":\"2\",\"sleep\":0,\"globalmessage\":\"\",\"globalmedia\":\"\",\"data\":[{\"number\":\"1212\",\"message\":\"Test\"}]}")
