Send a message

Send a message

Sends an email, in-app or WhatsApp message from a teammate to a user or lead and returns the created message.

Note: Sends for real. A contact created moments earlier can return 404 until it is ready to be messaged, and no conversation exists until the contact replies.

Set up

Use the first option your agent supports.

API (official)

• Base URL: https://api.intercom.io
• Endpoint: POST /messages
• Auth: send the header Authorization: Bearer $INTERCOM_API_KEY
• Get a key: https://app.intercom.io/a/apps/_/developer-hub/app-packages
• Docs: https://developers.intercom.com/docs/references/rest-api/api.intercom.io

Before anything else, confirm access with the cheapest read-only call, like a list or a search. Never send or change anything to test access.

Rules

• Ask the user before anything that sends messages, costs money, or changes data, and say how many records it touches. One approval covers a batch the user has seen.
• Never print API keys.
