This repository contains the iOS and Android sample apps and API for creating third party sticker packs for WhatsApp.
The sample app is now localized to 60 languages, this is the same language set that WhatsApp supports.
In this release, two new fields are introduced for Android. "image_data_version" and "avoid_cache", it is important developers implement these fields properly and update the "image_data_version" when stickers are updated. This will ensure your app works well with WhatsApp Android app.
