Edits and deletes sync both ways between Jira and Slack
A synced conversation should stay clean on both sides. Fix a typo in Jira and the Slack thread updates to match; delete a wrong comment in Slack and it disappears from the ticket too — usually within seconds.
Add Threadmaker to Slack — free for up to 10 Jira users.
What syncs
If a Slack reply or a Jira comment is edited, the corresponding message on the
other side updates within seconds. Deletes work the same way — deleting a Slack
reply removes the matching Jira comment, and deleting a Jira comment removes the
Slack message. The [Alice via Slack] attribution prefix stays and
updates along with the edited content.
The per-project toggle
Edit and delete sync is controlled per project in Project settings → Apps → Threadmaker → Sync comment edits and deletes (default ON). Turn it off if your team needs synced comments to be immutable for compliance or audit reasons: edits and deletes then stop syncing in both directions — a Slack-side edit isn't written to Jira, and a Jira-side edit or delete isn't written to Slack. Comments created afterward still sync both ways.
Good to know
- Adding a file while editing a synced message propagates, within the 5 × 2 MB attachment limits. Removing a file does not retract the copy already synced — delete the whole message or comment to retract it.
- Race safety: if you edit a Slack reply then delete it moments later, the delete wins. Ordering on the destination side may vary, but the final state stays consistent on both.
FAQ
Can I make synced comments immutable? Yes — turn the toggle off. Edits and deletes then stop syncing in both directions; brand-new comments still flow.
Does deleting on one side delete on the other? Yes, when the toggle is on — a delete propagates across the boundary just like an edit.
