Open-source WhatsApp API. Managed hosting when you need scale.

Developer-First API

Clean RESTful endpoints, webhook event delivery, comprehensive documentation, and client libraries. Build WhatsApp integrations in minutes, not days.

Buttons & Lists

On WSAPI Cloud, send reply, link, copy-code and call buttons, or a pick-one list, from any WhatsApp number. The tap comes back as an event. No Business API account required.

Rich Media Messaging

Send and receive text, images, video, documents, voice notes, stickers, contacts, and locations. Edit, delete, pin, and react to messages.

Multi-Account + Streaming

Connect multiple WhatsApp accounts under a single API. Events are delivered via webhooks or Server-Sent Events (SSE) for real-time message processing.

Chatbots & Automation

Build chatbots, automate notifications for orders and confirmations, and personalize responses. No per-message fees unlike the official API.

Groups, Chats & Contacts

Create and manage groups and members. List, mute, pin, archive or delete chats, send typing indicators and read receipts, and fetch or update contact details.
