Comptes de service

Un compte de service est un type de compte Google qui peut être utilisé par une application pour accéder aux API Google par programmation via OAuth 2.0. Cette opération ne nécessite pas d'autorisation humaine. Au lieu de cela, elle utilise un fichier de clé auquel seule votre application peut accéder.

Avant d'en savoir plus sur les comptes de service, envisagez l'alternative beaucoup plus simple et vivement recommandée de la mise en œuvre du flux OAuth 2.0 pour les applications installées. Cette approche nécessite que l'utilisateur autorise manuellement l'application à générer un jeton d'actualisation, mais cette opération ne doit être effectuée qu'une seule fois, car ces jetons n'expirent jamais.

Nous espérons que vous suivez toutes ces instructions. Vous pouvez implémenter un compte de service de l'une des manières suivantes:

  • Si vos utilisateurs résident sur des domaines différents, utilisez un compte de service en tant qu'utilisateur Campaign Manager 360. Cela vous permet de vous connecter à plusieurs comptes appartenant à différentes agences en créant un profil utilisateur sur chaque compte et en les associant à un seul compte de service. Il s'agit de la méthode recommandée pour utiliser les comptes de service avec Campaign Manager 360.
  • Si vos utilisateurs résident sur un seul domaine qui vous appartient, mettez en place la délégation au niveau du domaine. Dans ce cas, vous devez disposer d'un accès administrateur à un domaine enregistré auprès de G Suite. Pour obtenir de l'aide concernant G Suite et / ou la configuration du domaine, consultez la page d'assistance de G Suite.

Prérequis

Pour implémenter un compte de service en tant qu'utilisateur Campaign Manager 360, sélectionnez l'onglet Utilisateur Campaign Manager 360. Pour implémenter la délégation au niveau du domaine, sélectionnez l'onglet Délégation ci-dessous.

Utilisateur de Campaign Manager 360

Vous devez avoir accès à un compte Campaign Manager 360 pour lequel l'accès à l'API est activé.

<ph type="x-smartling-placeholder">

Délégation
  1. Vous devez avoir accès à un compte Campaign Manager 360 pour lequel l'accès à l'API est activé.
  2. Vous devez disposer d'un accès administrateur à un domaine enregistré auprès de G Suite.
  3. Vous devez disposer d'un profil utilisateur Campaign Manager 360 associé à un ou plusieurs comptes associés à votre domaine enregistré dans G Suite. Les profils utilisateur associés à des comptes d'autres domaines (gmail.com, par exemple) ne peuvent pas être utilisés.

Configurer et utiliser un compte de service

Pour mettre en œuvre l'utilisation d'un compte de service en tant qu'utilisateur de Campaign Manager 360, sélectionnez l'onglet Utilisateur Campaign Manager 360. Pour implémenter la délégation au niveau du domaine, sélectionnez l'onglet Délégation ci-dessous.

Utilisateur de Campaign Manager 360
  1. Générez une clé de compte de service dans la console Google APIs.

    Attention:Il est important de protéger le fichier de clé qui permet à un compte de service d'accéder aux services Google pour lesquels il a été autorisé.
  2. Associez le profil utilisateur Campaign Manager 360 à l'adresse e-mail du compte de service obtenue à l'étape précédente, comme indiqué dans l'article Gérer l'accès des utilisateurs du centre d'aide.
  3. Implémentez le flux OAuth 2.0 de serveur à serveur dans votre application à l'aide du compte de service que vous venez de créer. Pour en savoir plus, consultez la section Exemples.

Délégation
  1. Générez une clé de compte de service dans la console Google APIs.

    Attention:Il est important de protéger le fichier de clé qui permet à un compte de service d'accéder aux services Google pour lesquels il a été autorisé. Cela est particulièrement vrai pour le flux de délégation au niveau du domaine, car le contrôle au niveau du domaine de G Suite permet au compte de service d'emprunter l'identité de n'importe quel utilisateur du domaine. Il est également recommandé d'autoriser les comptes de service à accéder chacun à une seule API Google (à l'aide du champ "scope" décrit à l'étape suivante). Il s'agit d'une mesure préventive visant à réduire la quantité de données auxquelles un pirate informatique peut accéder si le fichier de clé d'un compte de service est compromis.
  2. Déléguez une autorité au niveau du domaine à ce compte de service pour lui permettre d'emprunter l'identité des utilisateurs de votre domaine. Lorsque vous y êtes invité, indiquez les champs d'application d'API suivants:
    Champ d'application Signification
    https://www.googleapis.com/auth/dfatrafficking Accès en lecture/écriture au trafficking dans Campaign Manager 360.
    https://www.googleapis.com/auth/dfareporting Accès en lecture/écriture aux rapports Campaign Manager 360.
    https://www.googleapis.com/auth/ddmconversions Accès en lecture/écriture aux conversions hors connexion Campaign Manager 360.
  3. Implémentez le flux OAuth 2.0 de serveur à serveur dans votre application à l'aide du compte de service que vous venez de créer. Pour en savoir plus, consultez la section Exemples. N'oubliez pas que vous devez fournir un compte pour emprunter l'identité. Il doit appartenir au domaine pour lequel votre compte de service a reçu l'autorité au niveau du domaine à l'étape précédente.

Pour obtenir de l'aide concernant G Suite et / ou la configuration du domaine, consultez la page d'assistance de G Suite.
