Why teams switch

Built for the way developers actually ship.

Twilio and Meta’s Cloud API are great if your company already has a verified WhatsApp Business account. If it doesn’t, Chatmaid gets you sending today.

Chatmaid is independent and not affiliated with Twilio or Meta. You are responsible for following WhatsApp’s terms of service when using any messaging provider.

From zero to first message

Three steps. Roughly five minutes.

No business verification, no template gating. Connect a number with a QR scan and start sending — exactly the way you’d expect a developer API to work.

step 01

Sign up & generate a key

Create a free account, then generate a sandbox key (sk_test_*) from the dashboard. Live keys (sk_live_*) appear after you start a $7.99/mo subscription.

step 02

Connect WhatsApp via QR

Add a phone number in the dashboard and scan the QR code with the WhatsApp app on your phone. No Meta business verification, no template review, no SIM card.

→ scan with WhatsApp

status: connected

~58 seconds

step 03

POST /v1/messages/send

Send your first message immediately. Track status via polling or signed webhooks. The same key works for every endpoint listed in the API reference.

curl -X POST .../v1/messages/send \
  -d '{
     "to": "+15557654321",
     "content": "Hi!"
  }'

The toolkit

Everything you need in one API

Send, simulate, sign, scale. Five primitives that cover every WhatsApp delivery flow you'd ever ship.

CHATMAID · SEND

One POST. One message on WhatsApp.

A single endpoint sends text, media, and documents through any connected number. Idempotency keys make retries safe for any worker.

Trackable message IDs returned in ~200msPOST /v1/messages/send
Idempotency keys for safe retries
Text, image, document, audio, video
Same key for sandbox and production

RESTJSON

~/chatmaid

✓ queued      msg_abc123
✓ sent        184ms
↳ webhook     message.sent
✓ 1 message sent in 184ms

Everything you need

Production-ready primitives, not toy examples.

Idempotency, signed webhooks, a real sandbox, structured errors. The plumbing you’d end up building yourself — already done.

Send in one call

A single POST returns a trackable message ID. Idempotency keys let any worker retry safely.

Signed webhooks

Send and status events are HMAC-signed, retried with exponential backoff, and replayable from the dashboard.

X-Chatmaid-Signature: sha256=8e2a91…

X-Chatmaid-Event: message.sent

Real sandbox

sk_test_* keys simulate the full pending → sent lifecycle and fire real webhooks — without touching WhatsApp.

Multiple phone numbers

Route messages through different sender numbers. $2.99/mo per extra phone.

Structured errors

Every error returns a type, code, and hint. Your retry logic — and your AI agent — knows what to do without parsing prose.

{
"error": {
"type": "rate_limit",
"code": "too_many_requests",
"hint": "retry after 60s"
}
}

Built for AI agents

Hand WhatsApp to your coding agent.

Two ways to plug Claude Code, Cursor, Windsurf or Claude Desktop into Chatmaid. Pick whichever fits your stack — they're complementary.

Point your agent at our docs

Every page is published as plain markdown following the llms.txt standard. Pipe the bundle into your agent and it can compose every flow on its own.

MCP setup guide

Both paths use the same API key. Test in sandbox first with sk_test_* — nothing reaches WhatsApp until you flip to sk_live_*.

One flat fee. No per-message tax.

Sandbox is free forever. Production is a flat $7.99/month that includes your first phone number and unlimited messages on it.

Common questions

Chatmaid connects through the same protocol WhatsApp Web uses, so your number is treated like any other client. Bans happen when accounts behave like spam — unsolicited bulk messages to people who don’t have you in their contacts, or lots of “report” clicks. Stay within normal human-volume sending and you’re fine. If a number ever does get blocked, scan a new one from the dashboard and your API keys, webhooks, and history stay put.
