# Messaging Booking message operations ## Send a message for a booking - [POST /bookings/{bookingId}/messages](https://docs.bookabletech.com/apis/production/messagingapi/messaging/sendbookingmessage.md): Sends a plain-text message on the booking's operator↔partner conversation. Bookable stores the message and relays it over email to the other participant, who can reply from their normal mail client. The delivery target is derived from the caller's role — there is no recipient field: - Integration Partner — delivered to the venue operator (direction: partner_to_operator). - Venue group operator — delivered to the integration partner (direction: operator_to_partner). Attachments cannot be sent via this endpoint; add them by replying to the relay email instead. ## List messages for a booking - [GET /bookings/{bookingId}/messages](https://docs.bookabletech.com/apis/production/messagingapi/messaging/getbookingmessages.md): Returns all stored messages for the given booking's operator↔partner conversation, ordered by sentAt ascending (oldest first). Each message's direction states who sent it and who received it. Access is scoped to the caller's venue group: Integration Partners see only messages for bookings belonging to their associated venues.
