While creating OkHttpClient that will be used for Retrofit.

add an Interceptor like this.

 private val httpClient = OkHttpClient.Builder()
        .addInterceptor (other interceptors)
        ........................................

        //This Interceptor is the main logging Interceptor
        .addInterceptor { chain ->
            val request = chain.request()
            val jsonObj = JSONObject(Gson().toJson(request))

            val requestBody = (jsonObj
            ?.getJSONObject("tags")
            ?.getJSONObject("class retrofit2.Invocation")
            ?.getJSONArray("arguments")?.get(0) ?: "").toString()
            val url = jsonObj?.getJSONObject("url")?.getString("url") ?: ""

            Timber.d("gsonrequest request url: $url")
            Timber.d("gsonrequest body :$requestBody")

            chain.proceed(request)
        }

        ..............
        // Add other configurations
        .build()

Now your every Retrofit call's URL and request body will be logged in Logcat. Filter it by "gsonrequest"
