Introduction
The official WhatsApp Business Platform through a REST API — without applying to Meta yourself.
Genuka WA gives you access to Meta's official WhatsApp Business Platform through a plain REST API. No Meta developer account to create, no Business Verification to pass, no access token to rotate: Genuka is an approved Tech Provider and carries that complexity for you.
What you can do
Send messages
Text, media, buttons, lists, forms — plus approved templates to reach a customer outside the 24-hour window.
Receive events
Inbound messages, delivery and read receipts, template status changes, marketing opt-outs.
Automate campaigns
Broadcast a template to a contact list and track every send through to the read receipt.
Integrate in TypeScript
@genuka/whatsapp ships typed builders that reject invalid payloads before the network call.
Two rules to know before you start
WhatsApp is not a free-for-all sending channel. Two constraints shape every integration, and it is cheaper to meet them here than in your production logs.
The 24-hour service window
You may send a free-form message — text, image, buttons — only within 24 hours of the last
message you received from that contact. After that, only a template approved by Meta will be
delivered. Anything else fails with error 131047.
Opt-in is mandatory
You may only write to people who agreed to be contacted. A user can opt out of marketing messages at any time; you are notified by webhook and sending must stop immediately.
Where to start
New to the platform? Follow the quickstart: account, connected number, first message, in about ten minutes.
Integrating from existing code? Go straight to authentication, then sending messages.
