WhatsApp

Cross-platform messaging application for private chat, voice, and video calls with end-to-end encryption by default. Available on iOS, Android, and desktop, it delivers a familiar channel where over two billion people connect daily.

Over one billion people connect with business accounts each week across Meta messaging services, and hundreds of millions of conversations between people and businesses occur daily. WhatsApp Business Platform provides programmatic access for medium to large businesses through the Cloud API, REST endpoints for sending and receiving messages, and integrations with CRM, payment, and inventory systems. Developers build customer support bots, order notifications, and marketing flows on top of the same encrypted channel users already use for personal communication.

Key capabilities:

• Cloud API for programmatic messaging with templates and session-based replies
• End-to-end encryption for all personal and business chats
• Voice, video, and group calls integrated into the messaging experience
• Business catalog for showcasing products and services in-app
• Webhooks for inbound messages and delivery status
• Support for media, buttons, lists, and interactive message formats

Teams adopt WhatsApp to reach customers on a channel they already use, whether for support tickets, order updates, appointment reminders, or transactional notifications. The Cloud API fits into existing stacks via REST or official SDKs, and BSP partners offer managed hosting for teams that prefer not to run the integration themselves.
