API Xuất bản của Google Street View được xây dựng trên HTTP và JSON, do đó, mọi ứng dụng HTTP chuẩn đều có thể gửi yêu cầu tới API này và phân tích cú pháp các phản hồi.
Tuy nhiên, các thư viện ứng dụng API của Google cung cấp tính năng tích hợp ngôn ngữ tốt hơn, có mức độ bảo mật cao hơn và hỗ trợ thực hiện các lệnh gọi yêu cầu người dùng phải uỷ quyền. Các thư viện ứng dụng được cung cấp bằng một số ngôn ngữ lập trình. Bằng cách sử dụng các thư viện đó, bạn có thể tránh được việc phải thiết lập yêu cầu HTTP và phân tích cú pháp phản hồi theo cách thủ công.
Để bắt đầu, hãy chọn ngôn ngữ lập trình mà bạn đang sử dụng để phát triển. Chúng tôi vẫn đang bổ sung thêm ngôn ngữ.
