Un compte de service est un type de compte Google qui permet à une application d'accéder aux API Google par programmation via OAuth 2.0. Cette opération ne requiert pas d'autorisation humaine, mais utilise un fichier de clé auquel seule votre application peut accéder.
Avant d'en savoir plus sur les comptes de service, envisagez la solution la plus simple (et hautement recommandée) à mettre en œuvre le parcours d'application installé via OAuth 2.0. Cette approche nécessite que l'utilisateur autorise manuellement l'application à générer un jeton d'actualisation. Toutefois, 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 différents domaines, utilisez un compte de service en tant qu'utilisateur Campaign Manager 360. Vous pouvez ainsi 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 privilégiée pour utiliser des comptes de service avec Campaign Manager 360.
- Si vos utilisateurs se trouvent sur un seul domaine qui vous appartient, configurez la délégation au niveau du domaine. Dans ce cas, vous devez disposer d'un accès administrateur à un domaine enregistré avec G Suite. Pour obtenir de l'aide concernant G Suite et / ou la configuration d'un domaine, consultez la page d'assistance G Suite.
Prérequis
Pour implémenter 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.
Vous devez avoir accès à un compte Campaign Manager 360 pour lequel l'accès à l'API est activé.
- Vous devez avoir accès à un compte Campaign Manager 360 pour lequel l'accès à l'API est activé.
- Vous devez disposer d'un accès administrateur à un domaine enregistré avec G Suite.
- Vous devez disposer d'un profil utilisateur Campaign Manager 360 associé à un ou plusieurs comptes sous votre domaine enregistré dans G Suite. Les profils utilisateur associés à des comptes associés à d'autres domaines, comme gmail.com, ne peuvent pas être utilisés.
Configurer et utiliser un compte de service
Pour implémenter 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.
- Générez une clé de compte de service dans la console Google APIs.
Attention:Il est important de protéger le fichier de clé qui accorde à un compte de service l'accès aux services Google pour lesquels il a été autorisé. - Associez le profil utilisateur Campaign Manager 360 à l'adresse e-mail du compte de service obtenue à l'étape précédente, comme décrit dans l'article du centre d'aide Gérer les accès utilisateur.
- 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.
- Générez une clé de compte de service dans la console Google APIs.
Attention:Il est important de protéger le fichier de clé qui accorde à un compte de service l'accès aux services Google pour lesquels il a été autorisé. Cela est particulièrement vrai pour le flux de délégation au niveau du domaine, en raison du contrôle de G Suite au niveau du domaine qui permet au compte de service d'usurper l'identité de n'importe quel utilisateur du domaine. Il est également recommandé d'autoriser les comptes de service à accéder à une seule API Google chacun (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 en cas de piratage du fichier de clé d'un compte de service. - Déléguez l'autorité au niveau du domaine à ce compte de service pour lui permettre d'usurper 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/dfatraffickingAccès en lecture/écriture au trafficking Campaign Manager 360 https://www.googleapis.com/auth/dfareportingAccès en lecture/écriture aux rapports Campaign Manager 360. https://www.googleapis.com/auth/ddmconversionsAccès en lecture/écriture aux conversions hors connexion Campaign Manager 360. - 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 dont l'identité doit être empruntée. Il doit appartenir au domaine pour lequel votre compte de service a été délégué à l'échelle du domaine à l'étape précédente.
Pour obtenir de l'aide concernant G Suite et / ou la configuration d'un domaine, consultez la page d'assistance G Suite.
