PROJECT MANAGEMENT
Bridge comments between linked Trello cards and Linear issues
Relays new comments in both directions so a discussion on a Trello card appears on its Linear issue and vice versa, keeping product and engineering in one conversation.
How it runs
The automated pipeline, trigger to output.
- TriggerComment webhook from Trello or LinearHTTP webhook
- LogicIdentify source and resolve linked record
- LogicDrop bot-authored or unlinked comments
- ActionPost comment to the opposite systemLinear
- OutputRecord mirrored comment ID to block echo
What it does
When someone comments on a Trello card that is linked to a Linear issue, the comment is copied onto that issue, attributed to the original author. The reverse also holds: Linear comments flow back to the Trello card. Bot-authored and already-mirrored comments are skipped so the thread never loops.
When to use it
Use it when stakeholders live in Trello and engineers live in Linear, and important context keeps getting lost because each side only reads its own tool. This keeps a single shared conversation without forcing anyone to switch apps.
How it works
- 1A webhook trigger receives a new-comment event from either Trello or Linear.
- 2A logic step identifies the source tool and resolves the linked counterpart record.
- 3A second logic step drops the event if the comment was created by the bridge itself or has no linked counterpart.
- 4An action posts the comment to the opposite system, prefixing it with the original author's name.
- 5The flow records the mirrored comment ID to prevent echo loops on the next event.
