Quickstart

Blooio is a messaging API for iMessage and SMS. This guide sends your first message.

Get an API key

Create an API key in the Blooio dashboard. Keys look like bl_live_... and authenticate every request as a bearer token.

Send a message

Send a message to a chat addressed by the recipient's phone number or email. The identifier goes in the URL path, so URL-encode it (+ becomes %2B):

curl -X POST https://api.blooio.com/v2/api/chats/%2B15551234567/messages \
 -H "Authorization: Bearer bl_live_..." \
 -H "Content-Type: application/json" \
 -d '{ "text": "Hello from Blooio!" }'

The response contains the queued message with its message_id and status. Poll the message status endpoint or subscribe to a webhook to track delivery.

Receive replies

Create a webhook to get inbound messages delivered to your server in real time.

Get an API key

Create an API key in the Blooio dashboard. Keys look like bl_live_... and authenticate every request as a bearer token.

Send a message

Send directly to a recipient. Blooio chooses the sender from your API key's priority; no channel lookup is required:

curl -X POST https://api.blooio.com/v4/messages \
 -H "Authorization: Bearer bl_live_..." \
 -H "Content-Type: application/json" \
 -d '{
 "to": "+15551234567",
 "text": "Hello from Blooio!"
 }'

To send from a specific sender, add one from string: a phone number ("from": "+15551230001"), an alias for a non-numbered sender ("from": "support"), or an exact channel ID ("from": "ch_...") for advanced integrations. See Channels & senders for when to use each form.

The response contains the queued message, resolved chat_id, channel_id, and routing explanation. Poll the message status endpoint or subscribe to a webhook to track delivery.

Receive replies

Create a webhook to get inbound messages and lifecycle events delivered to your server in real time.
