Connect any WhatsApp number via QR scan in under 60 seconds. Send transactional messages, OTP alerts & notifications through a simple REST API — no approval process needed.
A complete toolkit for developers, small businesses, and hobbyists building WhatsApp-powered automations.
Link any WhatsApp number by scanning a QR code from your dashboard. No business verification required — works with personal numbers too.
Simple HTTP POST endpoints to send text, images, PDFs, audio, and location. Works with PHP, Python, Node.js, Java — any language.
Receive messages in real-time via configurable webhooks. Build two-way chatbots, auto-replies, and customer support flows.
Manage multiple WhatsApp numbers under one account. Each instance gets a separate API key and isolated session.
Send images, videos, PDFs, voice notes, stickers, and contact cards — all through the same simple API interface.
Pre-built plugins for WooCommerce, Tally, Busy, Google Sheets, Zapier, Make.com, and 50+ platforms. Custom integrations on paid plans — free.
Full message delivery logs, session health monitoring, webhook event history, and real-time connection status in one place.
All sessions run over encrypted tunnels. API keys are scoped per instance. Auto session recovery on disconnects.
Queue messages for future delivery. Set delays between sends for safer transactional use. Built-in rate-limiting controls.
We're transparent about limitations. Please read before signing up to ensure this fits your use case.
Need enterprise-scale or marketing messaging? SendWAPI is not the right tool for heavy-volume marketing. We recommend using the Official WhatsApp Business API (via Meta or BSPs like Twilio, 360dialog, WATI) for campaign-level usage, verified sender identity, and compliance protection. We're happy to help you get pointed in the right direction — contact our team.
No complex onboarding. No business verification. Just sign up, scan, and call the API.
Sign up at sendwapi.com, create a new WhatsApp instance, and copy your unique API key — all in under 60 seconds.
Open WhatsApp on your phone → Linked Devices → Link a Device → scan the QR in your dashboard. Connection goes live instantly.
Make a simple POST request. Your message is delivered. Use our plugins, webhooks, and dashboard to build your full workflow.
