Connect Slack to Trello

Trello holds the plan and Slack is where the team talks. Connect them so new clients and requests turn into Trello cards, and your team hears in Slack about what is new, what is due today and what needs attention.

What you can do with Slack and Trello

Trello cards from new work, with deadlines and alerts posted in Slack. These are ready-made starting points. Anything else you can describe works too.

Build your own

Build any Slack and Trello automation you can describe

The ideas above are ready-made starting points, not a fixed list. Describe what should happen between Slack and Trello in your own words, with your conditions, other apps or an AI step, and your assistant writes it, tests it and runs it on ClickRuntime.

  • Your own rules

    Conditions, thresholds, filters and exceptions, written the way you'd explain them to a colleague.

  • Any number of apps

    One automation can read from one app and update several others. Over 248 apps are ready, and anything with an API works too.

  • AI where it helps

    Summaries, classification, extraction and drafts use ClickRuntime's built-in AI, with no extra key.

  • On a schedule or on each event

    Runs as often as every 5 minutes, or the moment an app sends an event, and keeps track of what it already handled.

For example, ask your assistant

When someone reacts with :clipboard: to a message in #requests, create a Trello card with an AI-written title and the message as description.

Each afternoon, DM each person their Trello cards due tomorrow, but skip people with nothing due.

Use cases

Why people connect Slack and Trello

How the two apps work together

  • Trello webhooks send card created, moved and commented events to a ClickRuntime trigger link.
  • The script posts a message to a Slack channel or DM with the card name, list and link.
  • Slack events such as a message or emoji reaction reach a trigger link and create Trello cards.

  • Requests in Slack become cards

    Marketing and design teams turn requests posted in a Slack channel into Trello cards. The thread gets a reply with the card link.

  • Card moves posted to the team

    Project leads post in Slack when a card moves to Review or Done. Reviewers know when work is waiting for them.

  • Overdue card reminders

    Team leads get a daily Slack message listing overdue cards with the member and board. Nothing sits past its due date unnoticed.

  • Content calendar updates

    Content teams that plan posts in Trello post the day's scheduled cards in a channel each morning.

More apps

Slack, Trello and other apps in one automation

An automation isn't limited to two apps. Add the next step in another app and it runs as part of the same automation.

Cards with due dates on a calendar

When a Trello card gets a due date, add it to our team Google Calendar and post the date in #projects.

Typeform requests to Trello and Slack

When a design request comes in through Typeform, create a Trello card in Requests and post it in #design.

Weekly completed cards to Sheets and Slack

Every Friday, log cards moved to Done this week in my Throughput sheet and post the count in #team.
