WhatsApp Business API
Send and receive WhatsApp on the official WhatsApp Cloud API. Connect your WhatsApp Business Account with Meta Embedded Signup, then use the same Blooio endpoint you already use for iMessage, SMS, and RCS.
Blooio is a Tech Provider on the WhatsApp Business Platform. Your customers message your WhatsApp Business number. You send approved templates to open a thread, then free-form text, media, and interactive messages inside the 24-hour customer service window. Meta bills your WhatsApp Business Account directly — Blooio relays the messages and returns delivery, read, and failure events on your webhooks.
What the WhatsApp Business API includes
Official WhatsApp Cloud API — your WhatsApp Business Account, your number, Meta's platform
Embedded Signup: connect a WhatsApp Business Account in a few clicks
Template messages to start or reopen a conversation
Text, image, video, audio, document, reply buttons, lists, and CTA links inside the 24-hour window
Inbound messages plus sent, delivered, and read webhooks
Same v4 API as iMessage, SMS, and RCS — Meta bills your WhatsApp Business Account directly
How to connect WhatsApp Business
Onboarding uses Meta Embedded Signup. Your WhatsApp Business Account and phone number come from your Meta account — nothing to hand-enter.
1. Start a Blooio account
Sign up and open the dashboard. WhatsApp Business is a v4 channel on api.blooio.com, alongside iMessage, SMS, and RCS. You use the same API key.
2. Connect WhatsApp Business with Embedded Signup
Go to Integrations → WhatsApp Business → Connect. Meta's Embedded Signup has you log in with Facebook, choose or create a WhatsApp Business Account, pick the business phone number, and grant Blooio messaging permissions. Blooio registers the number and provisions the channel. There is no account id to paste.
3. Add a payment method in WhatsApp
In Meta's Tech Provider model, the business pays Meta directly. Add a payment method on your WhatsApp Business Account. Blooio relays messages and does not resell WhatsApp conversation charges.
4. Send on the v4 messages endpoint
POST to /v4/messages with the recipient in E.164 and your connected WhatsApp number as from. Inside the 24-hour window, send text, media, or interactive messages. Outside it, send an approved template. Inbound messages and delivery receipts arrive as webhooks.
When to use WhatsApp
International customers
WhatsApp is the default messaging app across most of the world. Keep iMessage for US iPhone threads and use WhatsApp Business for the audiences that live in WhatsApp.
Order, shipping, and appointment updates
Approved utility templates deliver notifications when the 24-hour window is closed. A customer reply opens free-form conversation for the next 24 hours.
Opt-in marketing
Approved marketing templates reach people who opted in, with buttons, lists, and media. Quality and messaging-limit tiers stay on Meta's side and are returned on the send.
Two-way support
Inbound WhatsApp messages open a chat on the same webhook stream as your other channels. Reply with text, images, documents, reply buttons, or a link button while the window is open.
WhatsApp is a separate channel from iMessage. Pair it with Twilio when you need carrier SMS, and with the Blooio REST API when the same workflow should pick a channel per audience. Full reference: WhatsApp Business guide.
WhatsApp Business API FAQ
Does Blooio offer a WhatsApp Business API?+
Yes. Blooio connects to the official WhatsApp Business Platform (Cloud API). You connect your own WhatsApp Business Account and phone number, then send and receive WhatsApp on the same v4 API you use for iMessage, SMS, and RCS.
How do I connect WhatsApp Business to Blooio?+
In the Blooio dashboard, open Integrations → WhatsApp Business → Connect. Meta Embedded Signup asks you to log in with Facebook, pick or create a WhatsApp Business Account, pick a business phone number, and grant Blooio the messaging permissions. Blooio then provisions a whatsapp_business channel. There is nothing to type in by hand.
What is the WhatsApp 24-hour customer service window?+
WhatsApp only allows free-form text, media, and interactive messages for 24 hours after a customer messages you. Each new inbound message resets that window. Outside it, you can send only Meta-approved template messages. Blooio checks this before the send so you get a clear error instead of a rejected relay.
Who pays WhatsApp message fees?+
Meta bills the business directly on the WhatsApp Business Account. You add a payment method there. Blooio relays messages as a Tech Provider and does not mark up or resell WhatsApp conversation charges. Blooio's own plans start at $39/month for the platform.
Does Blooio queue or retry WhatsApp sends?+
No. Blooio relays straight to Meta. Messaging-limit tiers, throughput, and errors come back as Meta returns them. If a send fails and Meta marks it retriable, your application decides whether to resend.
Can I send WhatsApp and iMessage from the same API?+
Yes. POST to https://api.blooio.com/v4/messages. Set the recipient in E.164 and set from to your connected WhatsApp number, or pass channel_type whatsapp_business so Blooio resolves the channel. The same endpoint sends iMessage, SMS, and RCS.
