Setting Up Trello Slack Integration: 2 Easy Methods

Aditya Jadon • Last Modified: January 20th, 2023

You might be a Project Manager or a team member in an ongoing project, no matter what your role in the project is, you need to collaborate with other members in the project and update them timely. Going through an inbox full of E-Mails or messages is an overwhelming job. Small projects don’t require Project Management tools. But to handle large projects where the manager needs to assign various tasks to different teams, then one should use the integration of 2 or more Project Management tools like Trello Slack Integration, which can increase the efficiency of their workflow.

Trello is a Project Management and collaboration tool that helps you organize projects into Boards. Trello can help you manage all the updates and progress of your projects. It uses Kanban View to fit your project data so that you can easily collaborate with others and keep track of deadlines. 

Slack is another tool used by many organizations to keep a stable workflow. Slack is a messaging app for businesses that helps you communicate efficiently with other team members. It is easier to communicate using Slack rather than normal E-Mails. Your team members can discuss the top updates on a running project in a single chatbox. But how tedious it is to frequently context switch between Trello and Slack for maintaining updates at both platforms simultaneously.

Trello Slack Integration is a perfect solution to extract the best out of your team coordination. You can import Trello Boards or Cards in the chatbox and discuss with other team members for updates, or you can also attach Slack conversations in Trello Cards. In this article, you will understand Trello and Slack. Also, you will learn how to integrate Trello Slack.
