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). Text, and on plans that include it, images, video, audio and documents too. 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 are on the Documentation page, and there is a live API tester on the API Keys 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.

Can I send images, video, audio, or documents?

There is no free plan, so media is part of the paid plans. Starter can send images and PDF files (up to 2 MB each); Pro and Business can send images, video, audio and documents (PDF, DOCX, XLSX, TXT, CSV). It works in two steps: upload the file through the API (or send a public link to a file you host), then send the returned link as a media message.

Limits: images up to 10 MB, video up to 60 MB and 2 minutes, audio up to 15 MB and 5 minutes, documents up to 20 MB (Starter: PDF only, 2 MB). Uploaded files count toward your plan's media storage (Starter 200 MB, Pro 500 MB, Business 2 GB) and are removed automatically after 30 days.

For everyone's safety every file is identified by its real content (not its name) and virus-scanned. Office files with macros, PDFs with scripts, executables and other unsupported types are rejected. The step-by-step guide, limits and error codes are in Sending Files in the docs, and plan details are on the Billing page.

Is WA Gateway trusted?

Yes. Passwords are bcrypt-hashed, API keys are stored hashed for authentication, plus an encrypted copy so you can reveal or copy your own key from the dashboard when you are logged in (a revoked key can no longer be revealed), 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.

Is there a free plan?

No. WA Gateway is a paid service: you need an active plan to connect a WhatsApp number and send messages. Plans start at ₹99 for 30 days (Starter). See the Billing page for all plans and top-ups.

Which countries is WA Gateway available in?

Currently India only. Our payments run on UPI, so we can only serve customers who can pay that way. Signing up needs an Indian mobile number (+91). If you're outside India you'll see a "not available in your region" page; we hope to open more countries later. Existing customers who are travelling can still log in.

What documents are needed to create an account?

None. Sign up with an email address and an Indian WhatsApp number (+91), 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.

WA Gateway plans and pricing

Need more messages in a month? Top-up packs never expire and stack on top of your plan quota. Top-ups are add-ons for a paid plan: they can only be bought and used while a paid plan is active. Yearly plans are billed once for 12 months at a discount.
