How to enable
Go to Settings → Capabilities and enable Trello. Then select a workspace secret with your API key and token, and enter your board ID(s) — see below for details.Example use cases
- Triage New Cards — “When a new card is created in the Inbox list, analyze it and move it to the appropriate list based on priority”
- Comment Responses — “When someone comments on a card asking a question, research the answer and reply”
- Weekly Cleanup — “Every Friday, archive all cards in the Done list”
- Cross-platform Sync — “When you receive an email about a project update, create a card in the Updates list”
Webhook events
When you configure a board ID, the agent automatically subscribes to that board and can react to events on it — card changes, comments, members, labels, checklists, attachments, and more. By default, agents respond to a small set of common events (card created, card moved between lists, comment added, label removed). You can customize which events trigger the agent in the Trello capability settings, and optionally scope each event type to specific lists so the agent only fires when something happens in the lists you care about. Mention the events you want to act on in your agent’s instructions so it knows what to do when they fire.How to get your Trello credentials
1
Create a Power-Up
Go to trello.com/power-ups/admin and click New to create a Power-Up. Fill in the required fields (name, email, etc.) and click Create.
2
Generate your API key
Open the Power-Up you created and go to the API Key tab. Click Generate a new API key and copy it. Also copy the Secret shown with the key.
3
Generate a token
In the same API Key section, click the Token link next to your key. Choose your permissions and expiration, then click Allow. Copy the token that appears.
4
Find your board ID
Open your Trello board in a browser. The board ID is in the URL:
trello.com/b/{boardId}/...You can watch multiple boards by providing comma-separated IDs.5
Configure in Abundly
Go to Settings → Capabilities and enable Trello. Under Trello API key and token, click Add Secret, paste the API key and token, put Trello’s Secret in API secret (signs webhooks), and give the secret a name. The new secret is selected automatically. All three values live in one workspace secret, so other agents can reuse it and you rotate it in one place. Then enter your board ID(s).Trello signs its webhook events with that secret, so the agent only accepts board events that really come from Trello and nobody else can send it fake events. The capability can’t be saved without it.Already set up? Agents set up before the signing secret existed keep working with unsigned events until they are saved again; then the Trello secret needs API secret (signs webhooks) — edit the secret to add it. An API key and token typed into the Trello card earlier keep working. Click Save as workspace secret on the card to copy them into a new secret, with nothing to re-enter. See keys stored directly on an agent.
