Organization Policy client libraries

This page shows how to get started with the Cloud Client Libraries for the Organization Policy Service API. Client libraries make it easier to access Google Cloud APIs from a supported language. Although you can use Google Cloud APIs directly by making raw requests to the server, client libraries provide simplifications that significantly reduce the amount of code you need to write.

Read more about the Cloud Client Libraries and the older Google API Client Libraries in Client libraries explained.

Install the client library

C++

For information about this client library's requirements and install dependencies, see Setting up a C++ development environment.

C#

Install-Package Google.Cloud.OrgPolicy.V2 -Pre

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

Go

go get cloud.google.com/go/orgpolicy

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

Java

Select one of the following options:

If you are using Maven with BOM, add the following to your pom.xml file:

<dependencyManagement>
  <dependencies>
    <dependency>
      <groupId>com.google.cloud</groupId>
      <artifactId>libraries-bom</artifactId>
      <version>26.74.0</version>
      <type>pom</type>
      <scope>import</scope>
    </dependency>
  </dependencies>
</dependencyManagement>
<dependencies>
  <dependency>
    <groupId>com.google.cloud</groupId>
    <artifactId>google-cloud-orgpolicy</artifactId>
  </dependency>
</dependencies>

If you are using Maven without BOM, add the following to your dependencies:

<dependency>
  <groupId>com.google.cloud</groupId>
  <artifactId>google-cloud-orgpolicy</artifactId>
  <version>2.82.0</version>
</dependency>

If you are using Gradle without BOM, add the following to your dependencies:
```
implementation 'com.google.cloud:google-cloud-orgpolicy:2.82.0'
```

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

libraryDependencies += "com.google.cloud" % "google-cloud-orgpolicy" % "2.82.0"

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

Node.js

npm install @google-cloud/org-policy

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

PHP

composer require google/cloud-org-policy

For more information, see Using PHP on Google Cloud.

Python

Install this library in a virtual environment using venv. venv is a tool that creates isolated Python environments. These isolated environments can have separate versions of Python packages, which allows you to isolate one project's dependencies from the dependencies of other projects.

With venv, it's possible to install this library without needing system install permissions, and without clashing with the installed system dependencies.

Select one of the following options:

Mac/Linux:

python3 -m venv YOUR_ENVIRONMENT
source YOUR_ENVIRONMENT/bin/activate
pip install google-cloud-org-policy

Windows:

py -m venv <your-env>
.\YOUR_ENVIRONMENT\Scripts\activate
pip install google-cloud-org-policy

Replace YOUR_ENVIRONMENT with the path to your virtual environment.

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

Ruby

gem install google-cloud-org_policy-v2

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

Rust

cargo install google_cloud_orgpolicy_v2

For more information, see Get started with Rust.

Set up authentication

To authenticate calls to Google Cloud APIs, client libraries support Application Default Credentials (ADC); the libraries look for credentials in a set of defined locations and use those credentials to authenticate requests to the API. 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.

For production environments, the way you set up ADC depends on the service and context. For more information, see Set up Application Default Credentials.

For a local development environment, you can set up ADC with the credentials that are associated with your Google Account:

Install the Google Cloud CLI. After installation, initialize the Google Cloud CLI by running the following command:
```
gcloud init
```
If you're using an external identity provider (IdP), you must first sign in to the gcloud CLI with your federated identity.
If you're using a local shell, then create local authentication credentials for your user account:
```
gcloud auth application-default login
```
You don't need to do this if you're using Cloud Shell.

A sign-in screen appears. After you sign in, your credentials are stored in the local credential file used by ADC.

Use the client library

The following example shows how to use the client library.
