Each app is listed under the Workspace to which it belongs. For Power-Ups, if a Power-Up has been added to a Workspace, it will be available for enablement on all of the boards that belong to that Workspace.

If this is your first time visiting the app admin portal, you'll be prompted to fill out the Joint Development Agreement.

Creating a new app

To create a new app, start by clicking the "New" button in the top right of the admin portal.

You'll be given an empty form to fill out.

Below is information about each field and what it is used for.

Field Name	Description
Name	The name of the app.
Workspace	The Trello Workspace that owns the app. For Power-Ups, the Power-Up will be available on the boards of the Workspace selected.

Support Email	We'll use this email when questions arise from users regarding your app or if we need to contact you regarding changes to the platform.
Author	The name to be displayed as the author in the directory and in authorization screens.
iframe Connector URL	If your app will be a Power-Up (i.e., it will use Power-Up capabilities), this URL will be used for the iframe connector that will be loaded when the Power-Up is enabled. If your app is not using Power-Up capabilities, you do not need to fill this out.

Once all the required fields are filled out, click "Create" to create your app!

Below are details on each of the fields:

What are capabilities?

If you're not familiar with all of the capabilities and what they do, we recommend you head over to the Power-Up capabilities documentation.

Generating an API key

To access the Trello API, you must generate an API key. To register an API key to your app, go to your app, navigate to the API Key tab and select the option Generate a new API Key.

For more information on how to perform API requests, please access our API Introduction page.

Collaborators

By default, apps can only be managed by admins of the Workspace that owns the Power-Up. You can add Trello members from your Workspace to be collaborators on an app if you want to extend access to other Workspace members.

From the Collaborators section in the left navigation, you can search for Workspace members and add them as collaborators on the app.

Collaborators have all the same permissions on the app as a Workspace admin; they can update listings, turn off/on capabilities, etc. The only thing they can't do is remove Workspace admins.

Listings

The Listings section allows you to manage how your Power-Up will be displayed to end users in the Power-Up directory. Head over to the Listings page for more information on how to manage listings.

Privacy and Compliance

The Privacy and Compliance section contains a form with fields that are related to how your app manages personal data. See our documentation for more information.

Distribution

For public Power-Ups, the Distribution section includes information regarding the Power-Up button. Head over to Power-Up Button for more information on how you can use the Power-Up button to distribute your Power-Up.

Deleting an app

To delete an app, select "Delete app" from the top-left navigation. You'll be prompted to confirm that you want to delete the app.

Public Power-Ups

Updating Public Power-Ups is the same as updating a custom Power-Up. You can follow the instructions above to change information regarding your Power-Up.

Keep in mind that any changes you make to the Power-Up will be reflected immediately to all of Trello's users.

Deleting Public Power-Ups

You can't delete a Power-Up that has been made public via the dev portal. To delete a public Power-Up, please reach out to go.trello.com/dev-support.
