Connect Trello and Slack to keep your team updated on project progress instantly. With Activepieces, you can automatically send Slack messages when Trello cards are created, moved, or updated, so everyone stays informed without having to check boards manually.

When a new card is created in Trello, Slack posts a message in the relevant project channel with the card name and link.

When a card moves to the “In Progress” list, Activepieces sends a Slack message tagging the assigned team member.

When a card is moved to “Completed,” Slack posts a celebration message in a results or wrap-up channel.

When a comment is added to a Trello card, Slack sends a direct message to the card’s assignee.

When a due date is approaching in Trello, Slack posts a reminder in the assigned user’s DMs.

When a new checklist is added to a card, Slack notifies the project manager for review.
