WhatsAPI

Email is dying as a notification channel

Email open rates average 22%. WhatsApp is at 98%. Businesses sending time-sensitive communications — OTPs, order confirmations, appointment reminders — need a more reliable delivery channel, but building directly on Meta's Cloud API requires significant infrastructure and compliance overhead.

Three-step integration on top of Meta's infrastructure

WhatsAPI wraps Meta's Cloud API with a simple developer-first interface: get an API key, connect a WhatsApp Business number via the Meta portal, then send messages with a single HTTPS POST. No SDK required — any language can integrate in minutes.

The platform handles template approval workflows, bulk sending (up to 1,000 messages per API call), real-time delivery and read receipts via webhooks, and retry logic. A no-code conversation flow builder sits alongside the API for teams who want automation without writing code. Billing is handled via Stripe with a freemium tier and per-seat plans.

Production-ready WhatsApp messaging for any stack

WhatsAPI abstracts the complexity of Meta's developer ecosystem into a clean REST API that any backend can call. E-commerce, healthcare, and support teams can add WhatsApp as a notification channel with the same effort as adding an email provider — and get significantly higher engagement in return.
