WhatsApp will allow anyone to add stickers that can be used to send along with the emojis in the app. Stickers are available within the new sticker icon in the text input field, which will open up a list of stickers.
As we see Facebook’s sticker system, first download the sticker pack you want before you can use it. For now, the stickers are created by WhatsApp designers along with a few collections from other designers.
WhatsApp has also added support for third-party sticker apps on Android and iOS, so if you have a sticker pack published to the Google Play Store or App Store, users can send those stickers in WhatsApp.
WhatsApp stickers update rolled in the latest beta version of WhatsApp.
