Often, the easiest way to learn how to use an API can be to look at sample
code. This page provides links to samples and a number of convenient ways
to access the Campaign Manager 360 API.

**Note:** See [Get Started](https://developers.google.com/doubleclick-advertisers/dtv2/getting-started) for Data Transfer v2.0 examples.

The Campaign Manager 360 API is built on HTTP and JSON, so any standard web stack
can send requests to it and parse the responses.

However, instead of creating HTTP requests and parsing responses manually,
you may want to use the Google APIs Client Libraries. The client libraries
provide better language integration, improved security, and support for making
calls that require user authorization.

In the tables below, the first column shows each library's stage of
development; note that some are still in early stages. The second column
links to the main page for each library.

> [!NOTE]
> **Note:** For libraries that have samples for the Campaign Manager 360 API, the third column in the table below links to them directly. If a library's samples page does not yet include a sample for this API, you can still use that library---simply adapt one of the existing samples as needed.
