Trello’s API and Golang

Among some of my earlier posts, I’ve been looking towards Golang as a tool for building some more command-line apps. To better understand how to use it for HTTP-based client work, I wanted to build a small command-line app to work with the Trello API. When working with it, I found a really excellent Golang API for the Trello API here:


Recently, my boss wanted to get a bi-weekly update of projects, tasks, and things I’ve been working on. This was more for him to have an idea what I was putting my time into, as well as having evidence for promotions, bonuses, etc. I track most of my work using Trello, so this seemed a perfect opportunity to pull all of this information out using the built-in Trello API that they so wonderfully provided us users.

Thus, let us introduce to the audience, Trackello, a CLI to track your work:

Trackello is a command-line tool to allow you to retrieve and get
information on your Trello boards.  This tool provides a list
of the previous 14 days of information on a board defined in
your 'config' file (see '--config' flag for info

  trackello [command]

Available Commands:
  boards      List all of your boards
  cards       List all of the cards on a particular board.
  config      Configure your Trello API keys and preferred Trello Board
  list        List activities on a board

      --appkey string   Trello Application Key
      --board string    Preferred Board ID
      --config string   config file (default is $HOME/.trackello.yaml)
  -h, --help            help for trackello
      --token string    Trello Token

Use "trackello [command] --help" for more information about a command.


To talk to the Trello API, you need two pieces:

  • Trello APP key
  • Trello Token

To get both of these, go to . You can get both the Application key and a personal Token. For my first iteration of this program, I assumed you would want to get information for one Trello board, which would be your /preferred/ board. This is not required for normal use, but makes things easier.

As always, the command-line options can help here:

$ trackello help config
Using config file: /<your_home_dir>/.trackello.yaml
To communicate to a Trello API, you will need to configure a
minimum of 3 parameters:
  - preferredBoard

If you do not know or have any of these, you can review  the documentation
on this site:

  trackello config [flags]

Global Flags:
      --appkey string   Trello Application Key
      --board string    Preferred Board ID
      --config string   config file (default is $HOME/.trackello.yaml)
      --token string    Trello Token

If you call this command and pass in the Global Flags, you will get a trackello.yaml file that has your configuration in it:

$ cat ~/.trackello.yaml
appkey: f3ff39c83d227a7243abf4df66ffffff
token: b448d5fb4f1af85f3fffffffffffffffffffffffffffffffffffffffffffffff
board: 572ffff7ffffffffffffff83

Listing A Specific Board’s Actions

By default, the trackello list command will show you a listing of all board actions that occured in the last two weeks:

Listing All Boards

Further, you can also list all of your boards using trackello boards
