How to connect Trello to OpenClaw

The ClawHub skill teaches OpenClaw about Trello, but the calls run through the ClawLink plugin and your connected account. Make sure Trello is connected in the dashboard, then start a fresh chat so OpenClaw reloads the tool catalog. If OpenClaw runs as a persistent gateway, restart it so the new tools register.

Reconnect Trello from the dashboard, then start a fresh chat if the runtime still has the old tool catalog loaded.

Trello tool schemas load on demand the first time a tool runs and are cached after that, so this error usually clears on its own: wait a few seconds and retry the same request. If every Trello call keeps failing with it in a fresh chat, reconnect from the dashboard, and contact support if it still persists — that pattern points to a configuration problem on our side, not something you can fix by reconnecting again.

Two usual causes. The connected account may not have access to the specific workspace, inbox, store, or project in the request — check that first. If access looks right, the agent may have sent a placeholder value (like "YOUR_ID" or an example id from documentation) instead of a real one: ask it to run a list or search tool first, then retry the action with a real id from those results. Most failures at this stage are one of these two, not ClawLink bugs.

Check board membership before anything else, because Trello's permission model is per board and this is what usually produces a 401 on one call while everything else works. The connected account must be a member of the board to read a private one and must have the right level to write to it, and an account that is an observer rather than a normal member can read a board and fail on every card change. The second thing to confirm is which account approved the connection: people commonly hold a personal Trello account and one tied to work, and the boards visible to the agent belong to whichever one you signed in as. If neither explains it, reconnect from the dashboard, which reissues the authorization cleanly.

Ask the agent to diagnose it:

Tell me which Trello account this connection is acting as, then list the boards you can actually see and your membership level on each. Do not retry the failed call yet.

Trello addresses objects by id, and the ids are opaque strings rather than the names people use. A prompt that names a list "Doing" or a card by its title gives the agent nothing to send, so it either guesses or fails, and a guessed id fails as a not-found. The reliable pattern is to have the agent fetch the board, then the lists on it, then the cards on the list it wants, using the ids from each step. The other cause is archived objects: Trello hides archived cards and lists from normal views but they still exist, so something that seems to have vanished may have been archived rather than deleted.

Ask the agent to diagnose it:

Fetch the board by name, show me its lists with their real ids, then show me the cards on the list I named with their ids. Do not act on anything yet.

This is a prompt-shape problem rather than a tool problem, and it is worth designing around because Trello writes are immediately visible to the whole board. An instruction like "clean up the done column" leaves both the selection and the meaning of done to the model. Ask it to list the cards it matched, with names and ids, and wait for your confirmation before it archives or moves anything. If something was archived by mistake it can be restored from Trello's board menu, so the damage is recoverable — but it is noisy in front of your team.

Try reconnecting Trello and complete the consent flow in the same browser session. Partial OAuth approvals or switching accounts mid-flow can leave the connection incomplete.

Yes. ClawLink is the fastest way to connect OpenClaw to Trello: link your Trello account once in the browser and OpenClaw can call the Trello API through 322 ready-made tools — no custom code or token handling.

Paste the setup prompt from this page into OpenClaw. It installs the ClawLink Trello skill from ClawHub, then you click Connect in the dashboard to authorize Trello. OpenClaw calls the tools from the next message — no config files or API keys to manage.

About two minutes. Sign in, click Connect next to Trello in the dashboard, authenticate, and OpenClaw can use it from the next chat message.

The alternative to ClawLink is usually manual OAuth app setup plus your own token handling, permission troubleshooting, and tool plumbing for OpenClaw. That is fine if you want to build and maintain the integration yourself. Most teams just want Trello working from chat.

No. The usual setup has you generate an API key from Trello's developer page, mint a token against it, and store both wherever the agent can read them — which is why so many Trello automations end up with long-lived credentials in a file. Here the authorization happens in the browser and the credential stays on the ClawLink server. You can disconnect from the ClawLink dashboard or revoke the application from Trello's own account settings, and either one ends access immediately.

The ones your account is a member of, plus public boards, exactly as in the Trello web app. Trello scopes access by membership rather than by workspace alone, so a board in your organisation that nobody added you to is invisible to the agent too, and the fix is joining the board in Trello rather than changing anything in ClawLink. This is the most common cause of an agent insisting a board does not exist when you are looking straight at it — usually it is signed in as a different Trello account than the one you assumed.

Yes. The toolset is unusually complete: creating and moving cards, managing lists and boards, checklists and checklist items, labels, attachments, comments, due dates, members, and the full action history behind every object. That last part is more useful than it sounds, because Trello records what happened as actions, so an agent can answer questions about how a card got where it is rather than only reading its current state.

The authorization is Trello's own, so you approve it on Atlassian's screen, the agent never sees a password, and access can be revoked from either side. The practical caution is that Trello writes are immediate and visible to everyone on the board — a card moved or archived by mistake is noticed by your team before it is noticed by you. Archiving in particular is the one to be careful with, so ask the agent to list what it intends to touch and confirm before it acts on a batch.
