Zapier allows you to link Trello and Slack without writing a single line of code. With the proper configuration, you can guarantee that your team is constantly in sync, whether it be card movement, assignments, or deadline adjustments.
- 
Choose your trigger – In Zapier, add Trello as the trigger app. "New Card Created," "Card Moved to List," and "Due Date Approaching" are some of the most common triggers. 
- 
Set your action in Slack – Define Slack actions, such as sending a message to a channel or informing a particular person. 
- 
Customize the message – Use Trello data such as card name, description, due date, and link to dynamically generate Slack notifications. 
- 
Add filters to limit noise – For example, only alert Slack when cards are added to a specified list, such as "To Review" or "Urgent." 
- 
Create several Zaps for granular control – One for card creation, one for due date reminders, and one for checklist completions. 
- 
Test and improve – Use Zapier's built-in test function to preview messages and troubleshoot your automation workflow. 
This design saves manual follow-ups while increasing transparency, which is particularly valuable for distant teams or cross-functional interactions.
