Cette page explique comment débuter avec les bibliothèques clientes Cloud pour l'API Cloud Functions. Les bibliothèques clientes facilitent l'accès aux API Google Cloud à l'aide d'un langage compatible. Bien que vous puissiez utiliser directement les API Google Cloud en envoyant des requêtes brutes au serveur, les bibliothèques clientes fournissent des simplifications qui réduisent considérablement la quantité de code à écrire.
Pour en savoir plus sur les bibliothèques clientes Cloud et les anciennes bibliothèques clientes des API Google, consultez la page Présentation des bibliothèques clientes.
Pour authentifier les appels aux API Google Cloud, les bibliothèques clientes sont compatibles avec le service d'Identifiants par défaut de l'application (ADC). Les bibliothèques recherchent des identifiants dans un ensemble d'emplacements définis et les utilisent pour authentifier les requêtes adressées à l'API. Le service ADC vous permet de mettre des identifiants à disposition de votre application dans divers environnements, tels que l'environnement de développement local ou l'environnement de production, sans avoir à modifier le code de votre application.

With ADC, you can make credentials available to your application in a variety of environments, such as local development or production, without needing to modify your application code.\n\nFor production environments, the way you set up ADC depends on the service\nand context. For more information, see [Set up Application Default Credentials](/docs/authentication/provide-credentials-adc).\n\nFor a local development environment, you can set up ADC with the credentials\nthat are associated with your Google Account:\n\n1.\n [Install](/sdk/docs/install) the Google Cloud CLI.\n\n After installation,\n [initialize](/sdk/docs/initializing) the Google Cloud CLI by running the following command:\n\n ```bash\n gcloud init\n ```\n\n\n If you're using an external identity provider (IdP), you must first\n [sign in to the gcloud CLI with your federated identity](/iam/docs/workforce-log-in-gcloud).\n2.\n\n If you're using a local shell, then create local authentication credentials for your user\n account:\n\n ```bash\n gcloud auth application-default login\n ```\n\n You don't need to do this if you're using Cloud Shell.\n\n\n If an authentication error is returned, and you are using an external identity provider\n (IdP), confirm that you have\n [signed in to the gcloud CLI with your federated identity](/iam/docs/workforce-log-in-gcloud).\n\n\n A sign-in screen appears.
