La API de Google Street View Publish se basa en HTTP y JSON, por lo que cualquier cliente HTTP estándar puede enviarle solicitudes y analizar las respuestas.
Sin embargo, las bibliotecas cliente de la API de Google ofrecen mejor integración de lenguajes y mayor seguridad; además, admiten las llamadas que requieren autorización de usuarios. Las bibliotecas cliente están disponibles en diversos lenguajes de programación. Con ellos, podrás evitar la necesidad de configurar manualmente las solicitudes HTTP y de analizar las respuestas.
Para comenzar, selecciona el lenguaje de programación que usas en la implementación. Seguimos agregando más idiomas.
