API Reference

For Android


First time here? Visit the Snap Kit developer portal to add your application, exchange keys, and get set up with the proper API credentials.

The Android Snap Kit SDK provides an API in Java, organized by kit:

  • Creative: Share media, stickers and other metadata to Snapchat.
  • Login: Allow your users to log in using Snapchat credentials and fetch their Bitmoji and identity data.
  • Bitmoji: Add a Bitmoji sticker tray to your app so users can communicate visually.

We recommend trying the getting started guides for Creative Kit, Login Kit, and Bitmoji Kit to get familiar with each. When you're ready to develop Snap Kit functionality in your app, this document provides the Android API components.

We hope you’ll find everything you need. Want to keep up?
