SMS

By default, messages are sent from a shared Poku number. You can reserve your own dedicated number or bring your own Twilio number. See supported countries for SMS availability. 
curl -X POST https://api.pokulabs.com/messages/sms \
  -H "Authorization: Bearer <your-api-key>" \
  -H "Content-Type: application/json" \
  -d '{
    "message": "Your appointment is confirmed for tomorrow at 2pm.",
    "to": "+12155551234"
  }'

​
WhatsApp

By default, messages are sent from the Poku WhatsApp account and wrapped in a fixed template: “Notification from AI agent: {{message}}. No response required.” To use your own WhatsApp number, you need a Meta-approved template. 
curl -X POST https://api.pokulabs.com/messages/whatsapp \
  -H "Authorization: Bearer <your-api-key>" \
  -H "Content-Type: application/json" \
  -d '{
    "message": "Your appointment is confirmed for tomorrow at 2pm.",
    "to": "+12155551234"
  }'
“Notification from AI agent: Your appointment is confirmed for tomorrow at 2 pm. No response required.”
See the full Send WhatsApp API reference.

Slack

Prerequisite: The recipient must join the Poku Slack workspace to receive messages. To send from your own workspace, install the Pokubot and pass your workspace ID as from. 
curl -X POST https://api.pokulabs.com/messages/slack \
  -H "Authorization: Bearer <your-api-key>" \
  -H "Content-Type: application/json" \
  -d '{
    "message": "Your appointment is confirmed for tomorrow at 2pm.",
