Making Concurrent API calls Asynchronously (Is this Correct?)

 async Task SendUserInfoRequestAsync() {
        if (string.IsNullOrEmpty(sessionCache.loginToken)) {
            Debug.LogError("No login token found.....");

        }
        Uri userInfoUri = new Uri(new Uri(baseUrl), userInfoRoute);

        using (HttpClient client = new HttpClient()) {

                client.DefaultRequestHeaders.Authorization = new System.Net.Http.Headers.AuthenticationHeaderValue("Bearer", sessionCache.loginToken);

                Task<HttpResponseMessage> task2 = client.PostAsync(getUserInfoUri, null);
