A messaging API that lets businesses send WhatsApp messages and documents from their own number, programmatically.
The problem it solves: a small business wants to send order confirmations, receipts and invoices on WhatsApp — where their customers actually are — but the enterprise options are heavy, slow to get approved, and priced for companies far larger than them.
So I built the alternative. One REST endpoint to send a message, another to attach a PDF, and delivery webhooks so your system knows what landed. OTP codes with expiry and attempt limits for login and 2FA. SDK examples in seven languages, a dashboard to manage it, and a subscription that starts at $19/month.
I designed, built and shipped the whole thing — API, dashboard, billing, docs and marketing site. Node.js and TypeScript on the backend, Astro for the site.
