ActiWAPI is a multi-tenant WhatsApp SaaS platform and messaging API for businesses. Connect WhatsApp numbers, send messages via REST API, run bulk WhatsApp campaigns, manage contacts, receive webhook events, and bill through Razorpay — all from one developer-friendly dashboard.
Sign up for a free ActiWAPI account and verify your email. Your 7-day WhatsApp API trial starts automatically with no credit card required. Connect a WhatsApp session by scanning the QR code in your dashboard, then send your first message via the REST API or dashboard.
ActiWAPI uses session-based WhatsApp Web connectivity — you connect your own WhatsApp number via QR scan. This is ideal for many SMB and developer use cases. Ensure your WhatsApp messaging complies with WhatsApp Terms of Service, anti-spam rules, and local regulations in India and your operating regions.
Most teams connect their first WhatsApp session and send a test API message within 10 minutes. Full production WhatsApp API integration with webhooks, contact imports, and campaign automation typically takes a few hours depending on your stack.
After 7 days, your trial subscription expires and outbound WhatsApp messaging is paused until you choose a paid plan. Your contacts, campaigns, and session configuration are retained so you can upgrade and continue without re-importing data.
We accept payments through Razorpay including UPI, credit/debit cards, net banking, and wallets. All prices are in INR. Choose monthly billing or pay annually upfront with a 12-month commitment — annual discounts vary by plan and are shown on our pricing page.
