Download the latest client library for Python , unpack the code, and run python setup. Because the Python client libraries are not installed in the App Engine Python runtime environment , they must be vendored into your application just like third-party libraries.

Depending on your system, you may need to prepend these commands with sudo. Be sure to check our extensive Getting started guide for a quick overview of how to make your first request.

In order to prevent the accidental installation of API wrappers with breaking changes , it is highly recommended that you pin to the latest version yourself prior to using this library in production.

There are over Google API services. The chances are good that you will not want them all. This example will remove all services other than "Drive" and "YouTube" when composer update or a fresh composer install is run. If you prefer not to use composer, you can download the package in its entirety.

The method used is a matter of preference, but it will be very difficult to use this library without first understanding the JSON syntax for the API , so it is recommended to look at the APIs Explorer before using any of the services here.

The authorize method returns an authorized Guzzle Client , so any request made using the client will contain the corresponding authorization. It is recommended to use another caching library to improve performance.

This can be done by passing a PSR-6 compatible library to the client:. In this example we use PHP Cache. Add this to your project with composer:. When using Refresh Tokens or Service Account Credentials , it may be useful to perform some action when a new access token is granted.

To do this, pass a callable to the setTokenCallback method on the client:. This library supports the use of Charles Web Proxy. One additional step is required in Charles to view SSL requests.
