Trello

Business

Integrate Trello with Appsmith to create, update, search, and delete cards or boards without leaving your app. Each Trello action returns JSON so you can bind card metadata to widgets, trigger follow-up workflows, or keep your boards in sync with other datasources.

Connect Trello​

  1. In Appsmith, create a new Trello datasource.
  2. To authorize Trello, log in to your Trello account, review the requested permissions, and click Allow to grand Appsmith access to your Trello account.
  3. Once connected, you can create a new API by clicking the respective button in the upper right.

Query Trello​

Use the command selector in the query form to pick the Trello operation you need. Each command below lists its parameters along with tips for finding IDs inside Trello.

Find the Trello IDs​

Many of the commands require you to enter certain Trello IDs as parameters. To get those IDs, you can either export your Trello board as a JSON file or install the API Developer ID Helper Power-Up.

Export the Board Data as JSON File​

To export the board data as a JSON file, follow the steps below:

  1. Go to your Trello workspace and select a board.
  2. Click the three dots (...) on the upper-right corner.
  3. Click Print, export, and share.
  4. Select Export as JSON.

  1. Open the JSON file in a text editor or JSON viewer and grab the IDs:
  • id: the id of the Trello board
  • idOrganization: the id of the workspace
  • cards > id: the id of each card
  • labels > id: the id of each label
  • lists > id: the id of each list
  • members > id: the id of each member
  • checklists > id: the id of each checklist of the card

Similarly, you can only export a card as JSON by accessing the card, clicking the three-dots menu > Share > Export JSON.

Install the API Developer ID Helper Power-Up​

The API Developer ID Helper Power-Up allows Trello API Developers easy access to the technical IDs of a Trello Board (Board ID, List ID, and Card ID) instead of using the JSON export method. Click Add Power-Up, then select a board and click Add. Once added, go to the board and follow the instructions from the power-up's page to get the IDs.

Get boards member belong to​

Returns all boards accessible to the authenticated Trello member—ideal for populating board pickers without hardcoding IDs. No inputs required.

Custom action​

Use Custom Action when you need a Trello REST endpoint that is not modeled above. The form lets you supply the HTTP method, path (for example, https://api.trello.com/1/cards/{cardId}/attachments), query parameters, and body. Appsmith automatically injects the OAuth token from your datasource, so you only have to reference Trello’s API docs for the payload structure.
