title: 1006: Channel message id inbound only. | API Docs
description: channel_message_id cannot be supplied on a send.
---

**HTTP status:** `422`.

channel\_message\_id is an inbound-only fact the channel assigns; a send must not carry one. Remove the field and resend.

## Troubleshooting

- Address a reply with reply\_to\_message\_id, using the message id this API returned or delivered in an event.
