CONVERSATION REPLY

Service

Not a send category - a separate, follower-scoped capability for replying to a customer who actively follows your business.

Requirements

Your developer app token must carry the service scope. The recipient must actively follow your business (marketing opt-in is not required). The business account must be live.

Endpoint

POST/v1/service/:phoneNumber/messagesSend free-form text to a follower.

:phoneNumber is your business's own ChatX phone number, not the recipient's number or an account ID. The request body is always plain text:

{
  "to": "+15559876543",
  "body": "Thanks for reaching out - here is the update you asked about."
}

Rate-limited to one message per recipient per minute, tracked separately from category sends - sending a category message to the same recipient does not count against this limit, and vice versa.

See the API reference for error codes, or Message types for how this compares to the send categories.
