We make WhatsApp automation effortless for developers
WAStack.in was built to eliminate the friction of official WhatsApp API onboarding. No BSP contracts, no Meta approvals, no weeks of waiting. Just scan a QR code, and your WhatsApp number has a production-ready REST API in under two minutes.
Our Mission
To give every developer, startup, and agency a fast, secure, and reliable way to build on WhatsApp — without bureaucratic friction or vendor lock-in.
The official WhatsApp Business API is powerful, but the onboarding process creates a bottleneck for small teams and fast-moving startups. BSP applications, Meta verification, phone number provisioning, and template approval queues can take weeks. WAStack exists to bypass that friction entirely.
We let you connect an existing WhatsApp number via a QR scan, then expose that session as clean REST APIs, signed webhooks, and live event streams. Your team can ship a messaging integration, support bot, or campaign workflow in an afternoon — not a quarter.
The Problem We Solve
Side-by-side comparison of the official WhatsApp Business API onboarding vs. WAStack.
Official API Onboarding
Weeks of BSP contracts, Meta approvals, phone provisioning, and template review queues.
WAStack: Scan a QR code. Your APIs are live in under 2 minutes.
Template Restrictions
Every outbound message must use a pre-approved template with strict formatting rules.
WAStack: Send any text, media, document, or contact — no templates required.
Per-Message Pricing
Official API charges per conversation window. Costs scale unpredictably.
WAStack: Flat monthly plans. Unlimited messages on Pro and Enterprise.
Vendor Lock-In
Tied to a BSP provider's dashboard, pricing, and support SLAs.
WAStack: Your existing WhatsApp number. Your REST APIs. Cancel anytime.
