This page shows how to get started with the Cloud Client Libraries for the Cloud Functions API. Read more about the client libraries for Cloud APIs, including the older Google APIs Client Libraries, in Client Libraries Explained.
Installing the client library
For more information, see Setting Up a C# Development Environment.
Install-Package Google.Cloud.Functions.V1 -Pre
For more information, see Setting Up a Java Development Environment.
<dependency> <groupId>com.google.cloud</groupId> <artifactId>google-cloud-functions</artifactId> <version>1.0.8</version> </dependency>
If you are using Gradle, add the following to your dependencies:
If you are using sbt, add the following to your dependencies:
libraryDependencies += "com.google.cloud" % "google-cloud-functions" % "1.0.8"
For more information, see Setting Up a Node.js Development Environment.
npm install --save @google-cloud/functions
Setting up authentication
To run the client library, you must first set up authentication by creating a service account and setting an environment variable. Complete the following steps to set up authentication. For other ways to authenticate, see the GCP authentication documentation.
In the Cloud Console, go to the Create service account key page.Go to the Create Service Account Key page
- From the Service account list, select New service account.
- In the Service account name field, enter a name.
- Don't select a value from the Role list. No role is required to access this service.
- Click Create. A note appears, warning that this service account has no role.
- Click Create without role. A JSON file that contains your key downloads to your computer.
Create the service account. Replace NAME with a name for the service account.
gcloud iam service-accounts create NAME
Generate the key file. Replace FILE_NAME with a name for the key file.
gcloud iam service-accounts keys create FILE_NAME.json --iam-account=NAME@PROJECT_ID.iam.gserviceaccount.com
Provide authentication credentials to your application code by
setting the environment variable
Replace [PATH] with the file path of the JSON file that contains your
service account key. This variable only applies to your current shell session,
so if you open a new session, set the variable again.
Linux or macOS
