Dado que la Content API te permite interactuar de forma programática con Google Merchant Center, el primer paso para usarla es configurar y probar tu cuenta de Merchant Center.
Para crear y probar tu cuenta de Merchant Center, completa los siguientes pasos:
En Merchant Center, busca el identificador único de tu cuenta, que es el número que aparece en la esquina superior derecha de la página, sobre la dirección de correo electrónico de la cuenta.
En la sección Credenciales, selecciona Google OAuth 2.0 y Clave de API.
Haz clic en Ejecutar.
Si es necesario, accede con la Cuenta de Google asociada a tu cuenta de Merchant Center.
Si tu cuenta de Merchant Center está configurada correctamente, la solicitud se realizará con éxito y devolverá un código de respuesta HTTP 200. Sin embargo, como acabas de crear una cuenta nueva, es posible que el método products.list no devuelva ningún producto. Más adelante en esta guía, agregarás un producto y, luego, volverás a llamar a products.list para confirmar que la operación se realizó correctamente.
