Send a message into a conversation
The conversation-scoped form of a send, with the same body and the same idempotency rules as POST /v1/messages. It answers 201 and wraps the committed message in an array of one, which is the shape shipped clients read; /v2 returns the message on its own. Both commit exactly one message.

agentTokenuserSession
Agent Token (rly_live_…), shown once when the agent is created.
Headers
A legacy way to carry message_id for clients that cannot put it in the body. It is read only when it is itself a msg_ id; any other value is ignored and the server mints the id.
Pattern:
^msg_[0-9a-hjkmnp-tv-z]{26}$Path Parameters
Pattern:
^cnv_[0-9a-hjkmnp-tv-z]{26}$Body
application/json
The /v1 send body. Unknown fields are ignored rather than refused; /v2 refuses them.
Ordered parts of one message. An absent or empty array returns 422.
Required array length:
1 - 32 elements- Option 1
- Option 2
- Option 3
- Option 4
- Option 5
Show child attributes
Show child attributes
The client-minted canonical id and idempotency key. Omit it and Relay mints one, which makes the send non-idempotent.
Pattern:
^msg_[0-9a-hjkmnp-tv-z]{26}$Example:
"msg_01k1m4q9vn2r7t9b4c6qdh8xwy"
A reply target on a send: a message of this conversation, optionally one exact part of it.
Show child attributes
Show child attributes
Optional plain-language representation for notifications and search. Relay derives one when it is absent.
Response
The committed message, as an array of one.
Required array length:
1 elementShow child attributes
