Backup and DR Service client libraries

    This page shows how to get started with the Cloud Client Libraries for theBackup and DR API. Client libraries make it easier to accessGoogle Cloud APIs from a supported language. Although you can useGoogle Cloud APIs directly by making raw requests to the server, clientlibraries provide simplifications that significantly reduce the amount of codeyou need to write.

    Read more about the Cloud Client Librariesand the older Google API Client Libraries inClient libraries explained.

    Install the client library

    C++

    SeeSetting up a C++ development environmentfor details about this client library's requirements and install dependencies.

    C#

    If you are using Visual Studio 2017 or later, open the NuGet package manager window and type the following:

    Install-Package Google.Apis

    If you are using .NET Core command-line interface tools to install your dependencies, run the following command:

    dotnet add package Google.Apis

    For more information, seeSetting Up a C# Development Environment.

    Go

    go get -d google.golang.org/api/...

    For more information, seeSetting Up a Go Development Environment.

    Java

    Note that the Google API Client Library for Java does not currently support Android.

    If you are using Maven, add this to your

    pom.xml
     file:

    <dependency><groupId>com.google.api-client</groupId><artifactId>google-api-client</artifactId><version>1.22.0</version></dependency>

    If you are using Gradle, add this to your dependencies:

    compile'com.google.api-client:google-api-client:1.22.0'

    If you are using SBT, add this to your dependencies:

    libraryDependencies+="com.google.api-client"%"google-api-client"%"1.22.0"

    For more information, seeSetting Up a Java Development Environment.

    Node.js

    npm install googleapis

    For more information, seeSetting Up a Node.js Development Environment.

    PHP

    composer require google/apiclient

    For more information, seeUsing PHP on Google Cloud.

    Python

    pip install --upgrade google-api-python-client

    For more information, seeSetting Up a Python Development Environment.

    Ruby

    gem install google-api-client

    For more information, seeSetting Up a Ruby Development Environment.

    Set up authentication

    To authenticate calls to Google Cloud APIs, client libraries supportApplication Default Credentials (ADC);the libraries look for credentials in a set of defined locations and use those credentialsto authenticate requests to the API. With ADC, you can makecredentials available to your application in a variety of environments, such as localdevelopment or production, without needing to modify your application code.

    For production environments, the way you set up ADC depends on the serviceand context. For more information, seeSet up Application Default Credentials.
