How it works

Live on WhatsApp in three steps.

No apps to install, no platform to migrate to. walpio operates your WhatsApp Business number — you stay the owner of everything.

Connect your account

Bring your own Meta WhatsApp Business account. Your number, your display name, your billing relationship with Meta — you keep full ownership, always.

We set you up

We onboard your number, register your message templates with Meta and hand you a single API key. Onboarding is done with you, not dumped on you.

Send with one call

POST a message. walpio picks the compliant route, delivers it and reports the full journey — sent, delivered, read — back into your message log.

The hard part, handled

The 24-hour rule ends here.

WhatsApp only allows free-form messages within 24 hours of a customer's last reply. Outside that window, only pre-approved templates deliver — get it wrong and your message silently never arrives.

walpio checks the window on every single send. Inside it, your text goes out as-is. Outside it, walpio automatically wraps the same text into your approved template. One endpoint, zero rules to remember — your message arrives either way.

  • Window state tracked per customer, per number
  • Automatic template fallback — no code changes
  • Honest errors when something genuinely can't deliver

Everything included

A complete gateway, not a thin wrapper.

Bring your own Meta

Your WhatsApp Business account stays yours — number, brand name, Meta billing and all. walpio operates it; you own it. Leave any time and everything goes with you.

Delivery tracking

Sent, delivered, read, failed — a full status timeline per message, streamed live from Meta and queryable in your message log.

Drop-in compatible

Requests and responses mirror Meta's Cloud API shapes. Any WhatsApp SDK or library you already use keeps working, unchanged.

Security by default

Credentials encrypted at rest with AES-256-GCM. Webhooks verified by signature on every event. API keys stored only as hashes — shown once, revocable instantly.

Isolated workspaces

Every business runs in its own isolated workspace — scoped API keys, per-workspace rate control, and a strict wall between your data and anyone else's.

Built to operate

A public health endpoint, complete message logs and honest error semantics — a 4xx means don't retry, a 5xx means try again. No mystery failures.

Pricing

Simple plans. Serious value.

Monthly, no setup fee, cancel anytime. Meta's own conversation fees are billed by Meta directly to you — we never mark up your traffic.

For developers

If you can call an API,
you can send WhatsApp.

One endpoint, Cloud-API-compatible shapes, bearer auth. The example below is the entire integration.

# Send a WhatsApp message — that's the whole integration.
curl -X POST https://api.walpio.com/v1/messages \
  -H "Authorization: Bearer wp_live_····" \
  -H "Content-Type: application/json" \
  -d '{
    "to": "9715XXXXXXXX",
    "type": "text",
    "text": { "body": "Your order is out for delivery today." }
  }'
# 200 — accepted by WhatsApp, id returned for tracking.
{
  "messaging_product": "whatsapp",
  "messages": [{ "id": "wamid.HBgLOTcxNTA..." }],
  "walpio": { "id": "f3a1c2…", "via": "text" }
}
# Same request, outside the 24h window — walpio wrapped it
# into your approved template automatically. Note "via".
{
  "messaging_product": "whatsapp",
  "messages": [{ "id": "wamid.HBgLOTcxNTA..." }],
  "walpio": { "id": "9d24b8…", "via": "template" }
}
Predictable errors. 4xx = permanent, don't retry. 5xx = transient, retry safely.
Signed webhooks. Every inbound event is HMAC-verified against your Meta app secret.
Live status. api.walpio.com/health — public, honest, always on.

FAQ

Answers, straight.

Something we didn't cover? Ask us directly — a human replies.

Yes. walpio is built on Meta's official WhatsApp Business Cloud API — the same infrastructure the largest platforms use. No unofficial clients, no gray-market tricks, no risk to your number.

Yes — and that's a feature. You bring your own Meta WhatsApp Business account: your number, your verified brand name, your direct billing with Meta. walpio operates it for you, but ownership never leaves your hands.

WhatsApp requires pre-approved templates for business-initiated messages. walpio detects this automatically on every send and wraps your text into your approved template — the message delivers either way, and the API response tells you which route was used.

We do it with you: connect your Meta account, register and approve your templates, hand you your API key, and send the first live message together. You're production-ready as soon as Meta approves your templates — usually within days.

Monthly plans starting at $29 — see pricing. No setup fee, cancel anytime, and a full refund within 7 days of your first payment if walpio isn't right for you. Meta's own per-conversation fees are billed by Meta directly to you — no hidden markup on your traffic.

Yes. Your Meta account, number and templates are yours, and our API mirrors the official Cloud API shapes — so there's nothing proprietary holding you. We'd rather keep you with service than with lock-in.
