# Client libraries and SDKs

> Official client libraries for the Mailchimp Marketing API, plus the Mobile SDK for iOS and Android.

## Official client libraries

Client libraries wrap the Marketing API in the idioms of your language, so you can work with audiences, campaigns, and reports without hand-rolling requests. Each is generated from the same specification as the [API reference](/marketing/api), so every endpoint is covered. Pick a language for installation and examples on GitHub.

## Mobile SDK

The Mailchimp Mobile SDK implements a mobile-oriented subset of the Marketing API for iOS and Android, so your app can add contacts to an audience, update them, and log in-app events. See the [Mobile SDK documentation](/marketing/build/start-developing/mobile-sdk) for installation, initialization, and reference.
