One key authenticates every request. Your Meta token never leaves our vault and never touches your code.
Authorization: Bearer kn_live_…Send
Text, templates, media, interactive buttons: one POST to api.kenari.dev, with the same payload as Meta's Cloud API.
POST /v23.0/{id}/messagesWhy not call directly?
You can, once you have the access. Getting it is the hard part.

Keep the WhatsApp Business app. Add the API on the same number.
No cutover
Your team keeps replying from the WhatsApp Business app while your code sends through the API on the same number.
History synced once
On connect, WhatsApp shares contacts and up to 180 days of chats. We pass them straight to your webhook and clear our copy once delivered.
The 24-hour window, handled
The sync can run only once, within 24 hours. We ask for your endpoint before the clock starts.
Everything the WhatsApp Business Platform does. Less of the paperwork.
Byte-for-byte forwarding
Request bodies pass through untouched. No re-serialising, no reordered keys.
Templates & interactive
Create and send templates, buttons, lists, media: every Cloud API message type.
Many numbers, one account
Connect several WhatsApp numbers per account, each isolated, with per-plan quotas.
Webhooks, delivered
Verified, fanned out to your endpoints, retried on failure, and signed with Standard Webhooks.
Tokens sealed at rest
Meta tokens are encrypted and bound to their row. API keys are HMAC-verified, never stored in the clear.
Access logs
Every call recorded with status and Meta's latency, so you can tell your latency from theirs.
One flat price per month. Priced in rupiah.
Every plan starts with a 7-day trial. Meta bills conversations directly; we add no markup.

Frequently asked questions
Infrastructure for the WhatsApp Cloud API. You call a REST API from your own code; we handle Meta access, token storage, webhooks and pacing.
No. kenari is an API for developers. Build your inbox or CRM on top of it.
Anything the Cloud API supports: text, media, templates, interactive buttons and lists, reactions, read receipts.
You can create one during Embedded Signup or connect an existing one, including a coexistence number used in the WhatsApp Business app.
A flat monthly fee per plan. Meta bills you directly for conversations, and we never mark that up.
Send your kenari API key as a bearer token. Never send your Meta token; we supply it.
Not for long. Messages you send go straight to Meta. Incoming events, message text included, are kept only to deliver your webhooks: 24 hours or 7 days, your choice, and synced chat history is cleared once delivered. Access logs keep status and latency, never bodies.
The version sits in the path, as it does with Meta: /v23.0/…. Call the version you'd call on Meta, and upgrade by changing the path.
