Do you find yourself managing projects on Trello and wishing you could also use Slack for communication simultaneously? Or perhaps you're interested in doing certain Trello tasks directly from Slack?

With Slack Trello integration, you can combine collaboration and communication so that your team doesn’t have to switch between tools all the time.

In this article, we'll explore everything about integrating Trello with Slack, including its benefits and a straightforward guide on how to do it.

Let's get started.

First of all, what is Slack Trello integration?

The Slack Trello integration allows users to connect their Trello boards with their Slack channels, enabling teams to manage projects and tasks directly within Slack. This integration facilitates the sharing of Trello cards and updates in Slack, allowing for real-time collaboration and communication. Users can create new Trello cards, update existing ones, and receive notifications about Trello activities without leaving the Slack interface.

Why should you integrate Trello with Slack?

If you’re using Trello a lot in your organization to manage projects or track tasks while also conversing on Slack, it makes perfect sense to link both tools up.

With this in mind, here are the main perks you can enjoy after integrating Trello and Slack:

Task automation

Linking Slack with Trello can transform how you work by automating routine tasks—like creating Trello cards from Slack messages.

90% of employees feel exhausted from repetitive and boring tasks that can be easily automated. With Slack and Trello integration, your team can have extra time for more meaningful work.

Quick feedback, quick progress

There's nothing like getting quick feedback to keep things moving. With Slack and Trello working hand in hand, you can get project approvals and input without leaving your chat. This means decisions happen faster, and projects don't get stuck as Slack serves as a channel to communicate feedback.

Project transparency

Worked on a project three months ago and can't quite remember what discussions you had within the team? With Slack and Trello's powers combined, you have a searchable history of all your project's milestones and discussions. This can help immensely when bringing new team members up to speed or reflecting on past decisions.

Custom notifications

Lastly, Slack Trello integration means you can tailor notifications so you're only alerted about the things that matter to you. This personalized approach means less time sifting through updates and more time focusing on what you do best.

Now that the benefits are clear, how do you actually integrate both apps? Let’s explore the available options.

How to integrate Slack with Trello

Before you can link both apps, you must ensure that you have them installed and that you’re logged in.

Now, when it comes to the actual integration, you have several ways to do it:

1. Trello App for Slack

The easiest way to integrate Trello with Slack is through the official Trello app for Slack. This integration allows users to add Trello cards to boards, join cards and boards, change due dates, and more directly from Slack.

Setting up: You can add the Trello app to your Slack workspace from the Slack App Directory. Once installed, link your Trello account by following the prompts.

Usage: With the app, you can create new Trello cards, add comments to cards, and receive notifications for card updates directly in Slack.

2. Slack Power-Up in Trello

Another way to integrate is using the Slack Power-Up in Trello. This feature allows you to attach Slack conversations to Trello cards, enabling a direct link to Slack discussions from your Trello board.

3. Custom integrations using APIs

For more specific needs, you can also develop a custom integration using the Trello and Slack APIs. This requires programming knowledge which might not be a viable option for most.

Setting up: Familiarize yourself with both the Trello API and Slack API documentation. Use your development skills to create a custom application that integrates the two services according to your requirements.

Usage: Deploy your custom integration for personal or team use, ensuring you handle authentication and permission scopes correctly.
