Two words on power ups

Power-Ups allow you to bring additional features to your boards and integrate your favorite apps right into Trello. They can pull information and data from outside services directly into Trello, giving you clear perspective on your favorite tools for work.

How to test

First thing, you need to be an administrator of a Trello Team, then head up for the trello Power up managment panel. Here you can see the different teams for which you can enable / disable or create new power ups. Click on your team name, then click on create a Power-up button.

Give your power up a name and select at least the card-back-section capability in the list.

Finally fill the iframe connector URL field with the adress where your power up is hosted. You can use serveo to expose your local developpment version of this power-up, but feel free to host it in another service as long as it's served over HTTPS.

Once everything is done, go for the menu in one of your team's board, click on the Power-Ups entry, your custom power up should show in the Custom section of the list !
