Provisioning and Sending WhatsApp Stickers with Vonage APIs

Stickers are visual artifacts used in WhatsApp chats, similar to emojis but with larger images. Anyone can create custom third-party sticker packs, which can be a novel way to build brand awareness and customer engagement. To publish a custom sticker pack, developers need to create a sticker app, release it to the Google Play store or Apple App Store, and follow specific requirements for sizing and format. Once published, customers can download and use stickers in their WhatsApp chats. Developers can provision stickers for use by their WhatsApp Business Account using the Vonage WhatsApp Provisioning API, which requires provisioning a WhatsApp deployment first. The process involves sending POST requests to specific endpoints with required data, such as the sticker pack name and publisher information. Once stickers are provisioned, developers can send them in WhatsApp messages using the Vonage Messages API by making a POST request with the sticker id.
