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 proporcionan una mejor integración de lenguajes y una mayor seguridad. Además, admiten la realización de llamadas que requieren autorización de usuarios. Las bibliotecas cliente están disponibles en varios lenguajes de programación. Con ellas, puedes evitar la necesidad de configurar las solicitudes HTTP y analizar las respuestas manualmente.
Para comenzar, selecciona el lenguaje de programación que usas en el desarrollo. Seguimos agregando más idiomas.
