POST/v1/conversations/{conversation_id}/reopenbeta

Reopen a conversation

Needs: Manage conversations: notes, assign, close, tags, reminders (inbox:write)
Plan: Any plan with API access
Limits: 60 a minute per key
Dry run: Yes — every check runs with ?dry_run=true, nothing changes
Undo: Close it again.

Reopens a closed conversation and starts a new episode, optionally with a title. SLA clocks follow the workspace's rules. Reopening one that is already open changes nothing (changed: false).

Try it

Path

conversation_idrequiredstring

The conversation id.

Edit as JSON

titleoptionalstring

A title for the new episode, e.g. "Refund follow-up" (up to 120 characters).

Idempotency-Keyoptional — made for you if empty

Protects against doing it twice if you retry: a retry with the same key gets the first answer back instead of running again.

Test mode (dry run): nothing will change

Run liveTurns test mode off for this page only. It switches back when you leave the page.
