This page shows how to get started with the Cloud Client Libraries for the Pub/Sub API. Read more about the client libraries for Cloud APIs 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#
For more information, see Setting Up a C# Development Environment.
Install-Package Google.Cloud.PubSub.V1 -Pre
Go

go get cloud.google.com/go/pubsub
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.
If you are using Gradle, add the following to your dependencies:
If you are using sbt, add the following to your dependencies:
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/pubsub
PHP
For more information, see Using PHP on Google Cloud.
composer require google/cloud-pubsub
Python

gem install google-cloud-pubsub
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++
Before trying this sample, follow the C++ setup instructions in the Pub/Sub quickstart using client libraries. For more information, see the Pub/Sub C++ API reference documentation.
To authenticate to Pub/Sub, set up Application Default Credentials. For more information, see Set up authentication for a local development environment.
