Android Retrofit 2.0.0-beta2 Post string body dynamic headers

Retrofit 2.0.0-beta2

@Headers({
            "Authorization: {authorization}",
            "Content-Type: application/json"
    })
    @POST("/api/{id}/action/")
    Call<String> postfn(@Header("Authorization") String authorization, @Path("id") String id, @Body String body);

I moved back to the stable version 1.9 and intercepting worked fine.

You can't put this two things together.

There are two ways to put dynamic headers on requests with retrofit 2.0

1: put it only in method signature

@Headers({
    "Content-Type: application/json"
})
@POST("/api/{id}/action/")
Call<String> postfn(@Header("Authorization") String authorization, @Path("id") String id, @Body String body);

2: using request interceptor to add fixed dynamic headers 

public class TraktvApiProvider implements Provider<TraktvApi> {

    public static final String BASE_URL = "https://api-v2launch.trakt.tv/";

    @Override
    public TraktvApi get() {
        Retrofit retrofit = new Retrofit.Builder()
                .baseUrl(BASE_URL)
                .addConverterFactory(JacksonConverterFactory.create())
                .build();

        retrofit.client().interceptors().add(new LoggingInterceptor());

        return retrofit.create(TraktvApi.class);
    }

    private class LoggingInterceptor implements Interceptor {
        @Override
        public Response intercept(Chain chain) throws IOException {

            Request request = chain.request();

            request = request.newBuilder()
                    .addHeader("trakt-api-version", "2")
                    .addHeader("trakt-api-key", "[YOUR-API-KEY]")
                    .build();

            Response response = chain.proceed(request);

            String bodyString = response.body().string();

            Log.d("Retrofit", "---------------------------------- REQUEST ----------------------------------");
            Log.d("Retrofit", String.format("%s - %s", request.method(), request.url()));
            Log.d("Retrofit", request.headers().toString());
            Log.d("Retrofit", "---------------------------------- REQUEST ----------------------------------");
            Log.d("Retrofit", "---------------------------------- RESPONSE ----------------------------------");
            Log.d("Retrofit", response.headers().toString());
            Log.d("Retrofit", "Body: " + bodyString);
            Log.d("Retrofit", "---------------------------------- RESPONSE ----------------------------------");

            return response.newBuilder()
                    .body(ResponseBody.create(response.body().contentType(), bodyString))
                    .build();
        }
    }
}
