Fast & Easy Integration
Access and integrate the WhatsApp API with a single click, works with the most popular languages.
More Than an API · A Full Platform
Rapiwa is a complete WhatsApp messaging platform — chatbots, automation, campaigns, and a team inbox — all on top of a developer-friendly API.
Connect multiple WhatsApp numbers by scanning a QR code and manage every device from one dashboard — no Meta Business approval required.
Answer customers 24/7 with an AI chatbot powered by your own OpenAI or Claude key, plus instant keyword auto-replies for common questions.
Build knowledge bases from text, PDF, DOCX, CSV, images, or your website so the bot answers from your own content, with a safe fallback reply.
Design no-code flows with triggers, conditions, and actions — welcome sequences, drip follow-ups, and time-based reminders that run on autopilot.
Send targeted campaigns to lists and segments, schedule them in advance, and let built-in pacing protect your number while you scale.
Organize contacts with tags, custom attributes, and CSV import. Build segments to reach exactly the right audience, and honor opt-outs automatically.
Handle live conversations as a team in real time, assign chats to members with role-based access — and pay only for the first message in a thread.
Receive incoming messages, delivery status, and read receipts in real time through HMAC-signed webhooks — the foundation for true two-way conversations.
Check whether a number is registered on WhatsApp before you send, so you protect deliverability and never waste credits on invalid contacts.
