Hi @Rohitsachdeva You can update provideNewsService() function content with the below code and add your interceptors or you can use DI to return your client from separate method.

val client: OkHttpClient = OkHttpClient.Builder().addInterceptor(Interceptor { chain ->
            val request: Request = chain.request()
            val newReq: Request = request.newBuilder()
                .addHeader("Authorization", format("token %s", "your token"))
                .build()
            chain.proceed(newReq)
        }).build()

        return Retrofit.Builder()
            .client(client)
            .baseUrl(BuildConfig.BASE_URL)
            .addConverterFactory(GsonConverterFactory.create())
            .addCallAdapterFactory(LiveDataCallAdapterFactoryForRetrofit())
            .build()
            .create(ApiServices::class.java)
