func main() {
	ctx := context.Background()

	// Build token source from credentials + cached token
	ts, err := blogger.TokenSourceFromJSON("credentials.json", "token.json")
	if err != nil {
		log.Fatal(err)
	}

	// Create authenticated HTTP client
	httpClient := blogger.NewHTTPClient(ctx, ts)

	// Create SDK client
	client := blogger.NewRawClient(httpClient)

	// Fetch authenticated user
	user, err := client.Users().Get(ctx, "self")
	if err != nil {
		log.Fatal(err)
	}
	fmt.Printf("Hello, %s!\n", user.DisplayName)

	// List blogs
	blogs, err := client.Blogs().ListByUser(ctx, user.Id)
	if err != nil {
		log.Fatal(err)
	}
	for _, b := range blogs.Items {
		fmt.Printf("- %s (%s)\n", b.Name, b.Url)
