How To Automark Trello Task As Done

How To Articles

Have you ever used Trello to organize your tasks but wanted a feature that automatically marks tasks as completed? If so, then I have some exciting news for you! After trying various methods and thoroughly exploring Trello’s API documentation, I have discovered a solution that enables you to automate this task. In this article, I will walk you through the process of automating the marking of Trello tasks as done, including my own tips and insights.


Before we dive into the technical details, let’s talk about why automating the task completion process in Trello can be beneficial. As someone who heavily relies on Trello to manage my daily tasks, I found that manually marking tasks as done can be time-consuming and prone to human error.

By automating this process, you can save time and ensure that tasks are consistently marked as done without any manual intervention. This can be especially helpful when working on a larger project with multiple team members, where task completion needs to be tracked accurately.

Getting Started

To begin automating the task completion process in Trello, we need to utilize a combination of Trello’s API and a programming language of our choice. For this article, I will be using Python, as it is a versatile and beginner-friendly language.

Before we start writing any code, we need to make sure we have the necessary credentials and access to Trello’s API. You will need to create a Trello account if you don’t already have one and generate an API key and token. You can find detailed instructions on how to obtain these credentials in Trello’s developer documentation.

Writing the Code

Once you have your API key and token, it’s time to start writing some code! We’ll be using Python’s Trello library, which provides a convenient way to interact with Trello’s API. If you haven’t installed it already, you can do so by running the following command in your terminal:

pip install trello

Once the installation is complete, we can start writing our script. Here’s an example of how we can automark a Trello task as done:

import Trello

# Initialize Trello client
client = Trello.TrelloClient(api_key='your_api_key', api_secret='your_api_secret', token='your_token', token_secret='your_token_secret')

# Obtain a reference to the board
board = client.list_boards()[0]

# Obtain a reference to the list
list_ = board.list_lists()[0]

# Obtain a reference to the task
task = list_.list_cards()[0]

# Mark the task as done

Running the Script

Now that we have our code ready, let’s see it in action! To run the script, open your terminal, navigate to the directory where you saved the script, and execute the following command:


Make sure to replace “” with the actual name of your script file.

After running the script, you should see the specified Trello task marked as done. You can customize the script further to automate this process for multiple tasks or even schedule it to run at specific intervals using task schedulers like Cron (on Unix-like systems) or Task Scheduler (on Windows).


Automating the task completion process in Trello can be a game-changer for productivity and task management. By leveraging Trello’s API and a programming language like Python, you can save time and ensure more accurate task tracking. Remember to experiment with the code and make it your own, adding personal touches and additional functionality as needed.

So, why wait? Give it a try and experience the benefits of automarking Trello tasks as done!
