Secret Manager client libraries

This page shows how to get started with the Cloud Client Libraries for the Secret Manager API. Read more about the client libraries for Cloud APIs in Client Libraries Explained.

Install the client library

C++

See Setting up a C++ development environment for details about this client library's requirements and install dependencies.

C#

For more information, see Setting Up a C# Development Environment.

Using PowerShell:

$ Install-Package Google.Cloud.SecretManager.V1 -Version 1.0.0

Using the dotnet CLI:

$ dotnet add package Google.Cloud.SecretManager.V1 --version 1.0.0

Go

For more information, see Setting Up a Go Development Environment.

$ go get cloud.google.com/go/secretmanager/apiv1
$ go get google.golang.org/genproto/googleapis/cloud/secretmanager/v1

Java

For more information, see Setting Up a Java Development Environment.

If you are using Maven, add the following to your pom.xml file. For more information about BOMs, see The Google Cloud Platform Libraries BOM.

<dependencyManagement>
  <dependencies>
    <dependency>
      <groupId>com.google.cloud</groupId>
      <artifactId>libraries-bom</artifactId>
      <version>26.19.0</version>
      <type>pom</type>
      <scope>import</scope>
    </dependency>
  </dependencies>
</dependencyManagement>

<dependencies>
  <dependency>
    <groupId>com.google.cloud</groupId>
    <artifactId>google-cloud-secretmanager</artifactId>
  </dependency>

If you are using Gradle, add the following to your dependencies:

implementation 'com.google.cloud:google-cloud-secretmanager:2.23.0'

If you are using sbt, add the following to your dependencies:

libraryDependencies += "com.google.cloud" % "google-cloud-secretmanager" % "2.23.0"

If you're using Visual Studio Code, IntelliJ, or Eclipse, you can add client libraries to your project using the following IDE plugins:

The plugins provide additional functionality, such as key management for service accounts. Refer to each plugin's documentation for details.

Node.js

For more information, see Setting Up a Node.js Development Environment.

$ npm install --save @google-cloud/secret-manager

PHP

For more information, see Using PHP on Google Cloud.

$ composer require google/cloud-secret-manager

Python

For more information, see Setting Up a Python Development Environment.

$ pip install google-cloud-secret-manager

Ruby

For more information, see Setting Up a Ruby Development Environment.

$ gem install google-cloud-secret_manager

Set up authentication

When you use client libraries, you use Application Default Credentials (ADC) to authenticate. For information about setting up ADC, see Provide credentials for Application Default Credentials. For information about using ADC with client libraries, see Authenticate using client libraries.

Use the client library

The following example shows how to use the client library.

C++

To learn how to install and use the client library for Secret Manager, see Secret Manager client libraries. For more information, see the Secret Manager C++ API reference documentation.

To authenticate to Secret Manager, set up Application Default Credentials. For more information, see Set up authentication for a local development environment.
