This document describes API Keys, when to use them, how to acquire them,
and how to use them with the Google API Client Library for .NET.
Introduction
When calling an API that does not access private user data,
you can use a simple API key.
This key is used to authenticate your application for accounting purposes.
You can read more on
API keys
in the Console documentation.
Note
:
If you
do
need to access private user data, you must use
OAuth 2.0
.
Using API keys
To use an API key, pass it to the
BaseClientService.Initializer
APIKey
property. The
Simple API Example
on the Get Started page provides a complete example that uses API keys.
By setting the
APIKey
property, you ensure that every call you make
to the service will include the API key.
