Replace a conversation's access mode and member list. Only the conversation owner can call this endpoint; every other caller receives a not-found response. Each call replaces the entire access control — the most recent successful update wins. Members can read and continue the conversation, but still need access to the conversation's agent. To learn more about agent conversations, refer to the agent chat documentation.
Access-control mode: private (only the owner and the listed members can read and continue the conversation), public (any user with access to the conversation's agent can read and continue it).
Values:privatepublic
entriesobject[] · max items: 100required
Members to share the conversation with. The list replaces the stored one; submit an empty list to unshare. Entries naming the owner are ignored. Must be empty when access_mode is public; repeated ids are rejected.
idstring · min length: 1 · max length: 1024required
Stable identifier of the user to share the conversation with: a Kibana user profile uid. Users without a profile cannot be granted access.
roleenumrequired
Role granted to the principal. member is the only role: it grants read and converse access to the conversation.
Not Found — no conversation with this ID is readable by the caller, or the caller is not its owner. Matches the existing conversationNotFound shape, so members cannot distinguish a conversation they may not re-share from one that does not exist.
