Installing and configuring the ONLYOFFICE integration module for Trello
To install the ONLYOFFICE application:
- Open your Trello board and click on Show menu on the right side.
-
Go to Power-Ups and search for ONLYOFFICE.
- Click on the ONLYOFFICE Power-Up and then Add. Confirm the addition, and ONLYOFFICE will be enabled for your board.
Once you have your ONLYOFFICE Docs instance ready, you’ll need to configure it in Trello:
-
Click on the ONLYOFFICE button on the right Power-Ups panel. Enter the following details:
- Document Server Address: The URL of your ONLYOFFICE Docs Cloud or self-hosted server.
- JWT Secret (Optional): To protect your documents, you can enable JWT (JSON Web Token). You can find this information in your ONLYOFFICE Docs settings or the registration email if using the cloud version.
- JWT Header: If using JWT, specify the custom header name here.
- Click Save to apply the settings.
Start using ONLYOFFICE in Trello
With everything set up, you can now work on your documents directly within Trello cards:
Viewing and Editing: You’ll see the ONLYOFFICE button in the Power-Ups section — click it to view the list of attachments. To edit a file, click Open in ONLYOFFICE next to the desired attachment.


Collaboration: To collaborate efficiently with your team, enable real-time co-editing by selecting either Fast or Strict mode, and make use of comments and Track Changes.


Saving changes: Changes are saved in a new file with the same name as the original. The edited version is available within the card for easy access.
