## What it does

If your delivery team prefers Trello for task management, bidirectional sync: Arya tasks become Trello cards, Trello cards become Arya tasks.

## Prerequisites

<Note>
  * Active account with Trello
  * **Admin** or **Manager** role on Arya to connect
  * OAuth authorisation (or API key, where applicable)
</Note>

## Connect Trello

<Steps>
  <Step title="Go to Settings → Integrations">Find **Trello** in the gallery and click **Connect**.</Step>
  <Step title="Authorise via OAuth">Opens Trello login page. Grant requested permissions.</Step>
  <Step title="Confirm in Arya">Arya tests the connection. If OK, you see "Connected" in green.</Step>
  <Step title="Configure preferences (optional)">Sync frequency, filters, field mapping. From **Settings → Integrations → \[Trello] → Configure**.</Step>
</Steps>

## What syncs

| Direction     | Entity                    |
| ------------- | ------------------------- |
| Bidirectional | Tasks ↔ Trello cards      |
| Bidirectional | Card status ↔ task status |
| Bidirectional | Comments and attachments  |

## Use in workflows

Once connected, Trello appears as an action in the [workflow builder](/en/automations/workflow-builder). You can:

* Trigger workflows from Trello events
* Use Trello as an action (e.g. create record, send message)

## Troubleshooting

<AccordionGroup>
  <Accordion title="Authorisation error">
    Expired or revoked token. Disconnect and reconnect.
  </Accordion>

  <Accordion title="Slow or failed sync">
    Check service API quota (rate limit). Reduce frequency if exceeding quota.
  </Accordion>

  <Accordion title="Data not synced">
    Verify field mapping and filters. Try manual sync from **⋯ → Sync now**.
  </Accordion>

  <Accordion title="Duplicate errors">
    Arya uses unique keys for matching. Configure key (email, external ID) in **Settings → Sync**.
  </Accordion>
</AccordionGroup>

## Disconnect

<Warning>
  Disconnection immediately stops synchronisation. Already-imported data stays in the workspace.
</Warning>

<Steps>
  <Step title="Go to Settings → Integrations">Find the Trello card.</Step>
  <Step title="Click Disconnect">Confirm. Access token is revoked.</Step>
