Una cuenta de servicio es un tipo de Cuenta de Google que una aplicación puede usar para acceder a las APIs de Google de forma programática a través de OAuth 2.0. Esto no requiere autorización de una persona, sino que utiliza un archivo de claves al que solo puede acceder tu aplicación.
Antes de leer más sobre las cuentas de servicio, considera la alternativa mucho más sencilla y altamente recomendada de implementar el flujo de aplicación instalada de OAuth 2.0. Este enfoque requiere que el usuario autorice manualmente a la aplicación para que genere un token de actualización, pero esto solo debe hacerse una vez, ya que estos tokens nunca caducan.
¿Sigues leyendo? Puedes implementar una cuenta de servicio de cualquiera de las siguientes maneras:
- Si tus usuarios residen en diferentes dominios, realiza la implementación con una cuenta de servicio como usuario de Campaign Manager 360. Esto te permite conectarte a varias cuentas que pertenecen a distintas agencias mediante la creación de un nuevo perfil de usuario en cada cuenta y la asociación a todas con una sola cuenta de servicio. Esta es la forma preferida de usar las cuentas de servicio con Campaign Manager 360.
- Si tus usuarios residen en un solo dominio de tu propiedad, implementa la delegación de todo el dominio. En ese caso, debes tener acceso de administrador a un dominio registrado en G Suite. Para obtener ayuda con G Suite o con la configuración del dominio, consulta la página de asistencia de G Suite.
Requisitos previos
Para implementar una cuenta de servicio como usuario de Campaign Manager 360, selecciona la pestaña Usuario de Campaign Manager 360. Para implementar la delegación de todo el dominio, selecciona la pestaña Delegación a continuación.
Debes tener acceso a una cuenta de Campaign Manager 360 con el acceso a la API habilitado.
- Debes tener acceso a una cuenta de Campaign Manager 360 con el acceso a la API habilitado.
- Debes tener acceso de administrador a un dominio registrado en G Suite.
- Debes tener un perfil de usuario de Campaign Manager 360 vinculado a una o más cuentas de tu dominio registrado en G Suite. No se pueden usar perfiles de usuario vinculados a cuentas de otros dominios, como gmail.com.
Configura y usa una cuenta de servicio
Para implementar con una cuenta de servicio como usuario de Campaign Manager 360, selecciona la pestaña Usuario de Campaign Manager 360. Para implementar la delegación de todo el dominio, selecciona la pestaña Delegación a continuación.
- Genera una clave de cuenta de servicio en la Consola de APIs de Google.
Precaución: Es importante proteger el archivo de claves que otorga a una cuenta de servicio acceso a los servicios de Google para los que se autorizó. - Asocia el perfil de usuario de Campaign Manager 360 al correo electrónico de la cuenta de servicio que obtuviste en el paso anterior, tal como se describe en el artículo del Centro de ayuda Administra el acceso de los usuarios.
- Implementa el flujo de servidor a servidor de OAuth 2.0 en tu aplicación con la cuenta de servicio que acabas de crear. Para obtener más información, consulta la sección de ejemplos.
- Genera una clave de cuenta de servicio en la Consola de APIs de Google.
Precaución: Es importante proteger el archivo de claves que otorga a una cuenta de servicio acceso a los servicios de Google para los que se autorizó. Esto es especialmente cierto para el flujo de delegación de todo el dominio debido al control a nivel del dominio de G Suite que permite que la cuenta de servicio suplante a cualquier usuario del dominio. También es una buena práctica permitir que las cuentas de servicio solo accedan a una API de Google cada una (a través del campo "scope" que se describe en el paso siguiente). Esta es una medida preventiva para mitigar la cantidad de datos a los que puede acceder un atacante en caso de que un archivo de claves de una cuenta de servicio se vea comprometido. - Delega autoridad en todo el dominio a esta cuenta de servicio para que pueda suplantar a otros usuarios del dominio. Cuando se te solicite, proporciona los siguientes alcances de la API:
Alcance Significado https://www.googleapis.com/auth/dfatraffickingTiene acceso de lectura/escritura a la coordinación de anuncios de Campaign Manager 360. https://www.googleapis.com/auth/dfareportingTiene acceso de lectura/escritura a los informes de Campaign Manager 360. https://www.googleapis.com/auth/ddmconversionsTiene acceso de lectura/escritura a las conversiones sin conexión de Campaign Manager 360. - Implementa el flujo de servidor a servidor de OAuth 2.0 en tu aplicación con la cuenta de servicio que acabas de crear. Para obtener más información, consulta la sección de ejemplos. Recuerda que deberás proporcionar una cuenta para usar la identidad y que esta debe pertenecer al dominio para el que se delegó a tu cuenta de servicio la autoridad de todo el dominio en el paso anterior.
Para obtener ayuda con G Suite o con la configuración del dominio, consulta la página de asistencia de G Suite.
