About WA Gateway

What service does WA Gateway provide?

WA Gateway lets you connect a WhatsApp number to your website, app, or backend, and send messages through a REST API. It's built for transactional messages specifically — OTP codes for login/signup verification, and order or payment status updates (successful, failed, pending). It's not a marketing/bulk-broadcast tool, and it doesn't do interactive buttons or catalogs — those features get flagged by WhatsApp's own systems on unofficial connections, so we deliberately left them out rather than ship something that gets your number banned.

How do I implement WA Gateway into my website or app?

Three steps: connect a WhatsApp number from your dashboard (scan a QR code, same as WhatsApp Web), generate an API key, then send a POST request with your API key, the session ID, a recipient number, and a message. That's it — no SDK to install. Full endpoint docs, request/response examples, and a live in-browser API tester are on the Documentation page. There's also a ready-to-paste prompt there for feeding the whole integration to ChatGPT or Claude if you'd rather have an AI write the integration code for you.

Is WA Gateway trusted?

Yes. Passwords are bcrypt-hashed, API keys are stored as one-way hashes (never recoverable, only shown once at creation), and every login is protected against brute-force attempts by tracking the targeted account itself, not just the source IP — so distributed attacks don't get a free pass. Webhook payloads are HMAC-signed so you can verify they actually came from us. New accounts are verified by both email and WhatsApp before they can connect a session, which keeps the platform free of throwaway/fake accounts. None of this is outsourced — it's built and actively maintained by one developer who uses the same infrastructure for his own projects.

What documents are needed to create an account?

None. Sign up with an email address and a WhatsApp number, verify both with the codes sent to you, and you're in. No ID upload, no business registration, no KYC paperwork — that's one of the main reasons people choose this over the official WhatsApp Business API, which requires Meta business verification.
