Turn a Slack message into a Trello card with one emoji
React with your ticket emoji and the message becomes a card on the right list, carrying the text, the person who wrote it and a link to the thread.
Trigger: Reaction added to a message
Action: Create a card
About 4 minutes to set up
How this flow works
Syncline watches Slack for Reaction added to a message. When that happens it runs Create a card in Trello with the fields you mapped.
- Invite Syncline to the channels and choose the emoji that means make this a card.
- Connect Trello and pick the board plus the list new cards land on.
- Map the message text onto the card name and the author onto members.
- React once, check the card, then post the emoji rule in the channel topic.
Field mapping
| From Slack | To Trello | Note |
|---|---|---|
| Message text | Card name | The first sentence becomes the card title and the rest is kept in the description. |
| Author | Members | The person who wrote the message is added to the card, matched by the email on their Trello account. |
| Channel | List | Channels map onto lists, so a bug reported in support does not sit next to a marketing idea. |
| Timestamp | Due date | The card is due a set number of hours after the message, which is how a response time becomes visible. |
Why teams run it
- Turning talk into work takes one click, from the phone too
- The thread link means the card never loses its context
- Requests stop being remembered and start being tracked
Who uses it
A team lead whose requests arrive as chat messages and used to disappear by the next morning.

Slack
Slack is where a team notices things, which makes it the best place to put an alert and the worst place to store one. Syncline sends messages into channels when something happens elsewhere, and turns the replies worth keeping into records.

Trello
Trello is the task board people actually keep updated, because moving a card takes one second. Syncline creates those cards from other systems and reports back when they move.
Questions
Can I use a different emoji per list?
Yes. One flow per emoji, each pointed at its own list. Three flows cover bug, content and finance without anyone learning a command.
What happens if two people react?
The first reaction creates the card and the second is ignored, because the flow records the message it already handled.
