Introducing a new way for people to express themselves with stickers. Whether with a smiling teacup or a crying broken heart, stickers help you share your feelings in a way that you can't always express with words. To start, we're launching sticker packs created by our designers at WhatsApp and a selection of stickers from other artists. Added support for third-party sticker packs to allow designers and developers around the world to create stickers for WhatsApp. To do this, we've included a set of APIs and interfaces that allow you to build sticker apps that add stickers to WhatsApp on Android or iOS.
