Visit OneMsgThe challenge
Businesses want to reach customers on WhatsApp without Meta Business verification or an engineering team — and developers want it wired into the systems they already run.
Our approach
Register, scan a QR code to connect WhatsApp, and launch a personalised campaign in about three minutes. Developers get a REST API for sending, webhooks for receiving and building bots, and ready-made samples in PHP, Node.js and cURL.
The result
A WhatsApp messaging panel for personal and business use, with a 7-day free trial and a developer tier.
