# Overview

> Kanban board tool for organizing tasks, cards, lists, and lightweight project management.

Use **Trello** through Corsair: one client, typed API calls, local DB sync, and incoming webhooks.

**What you get:**

* 25 typed API operations
* 5 synced entities (`boards`, `cards`, `labels`, `lists`, `members`) for fast `.search()` / `.list()`
* 6 incoming webhook event types

## Setup

<Steps>
  <Step title="Install">
    <CodeGroup>
      ```bash npm theme={null}
      npm install corsair @corsair-dev/trello
      ```

      ```bash yarn theme={null}
      yarn add corsair @corsair-dev/trello
      ```

      ```bash pnpm theme={null}
      pnpm install corsair @corsair-dev/trello
      ```

      ```bash bun theme={null}
      bun add corsair @corsair-dev/trello
      ```
    </CodeGroup>
  </Step>

  <Step title="Add the plugin">
    ```ts corsair.ts theme={null}
    import Database from 'better-sqlite3';
    import { createCorsair } from 'corsair';
    import { trello } from '@corsair-dev/trello';

    export const corsair = createCorsair({
    	plugins: [
    		trello(),
    	],
    	database: new Database('corsair.db'),
    	kek: process.env.CORSAIR_KEK!,
    	hub: {
    		projectApiKey: process.env.CORSAIR_API_KEY!,
    		signingSecret: process.env.CORSAIR_SIGNING_SECRET!,
    	},
    });
    ```

    Multi-tenancy is the default — scope calls with `corsair.withTenant(id)`. See [Quick start](/quick-start) for KEK + Hub keys, and [Multi-tenancy](/concepts/multi-tenancy) for account isolation.
  </Step>

  <Step title="Choose authentication">
    <Tabs>
      <Tab title="API Key (Recommended)">
        No setup required yet. When you make your first request as a tenant, Corsair prompts for the API key.

        Provider walkthrough: [Get Credentials](/plugins/trello/get-credentials).

        ```ts theme={null}
        trello()
        ```

        More: [API Key](/concepts/api-key)
      </Tab>
    </Tabs>
  </Step>

  <Step title="Connect a tenant">
    Mint a connect link and send the tenant to it. Hub hosts the page and delivers the result to your app — see [Connect / OAuth](/management/connect).

    ```ts theme={null}
    const { connectUrl } = await corsair.manage.connect.createLink({
    	plugin: 'trello',
    	tenantId: 'acme',
    });
    // redirect the user's browser to connectUrl
    ```
  </Step>
</Steps>

## Example API calls

**List cards**

```ts theme={null}
const tenant = corsair.withTenant('acme');
await tenant.trello.api.cards.list({ listId: '64a1b2c3d4e5f6a7b8c9d0e1' });
```

**Create a card**

```ts theme={null}
const tenant = corsair.withTenant('acme');
await tenant.trello.api.cards.create({ name: 'Follow up from Corsair', idList: '64a1b2c3d4e5f6a7b8c9d0e1' });
```

See the full list on the [API](/plugins/trello/api) page.

## Query synced data

Search synced cards without hitting Trello.

```ts theme={null}
const tenant = corsair.withTenant('acme');
const rows = await tenant.trello.db.cards.search({
	data: { closed: false },
	limit: 50,
});
```

Synced entities: `boards`, `cards`, `labels`, `lists`, `members`. See [Database](/plugins/trello/database) for filters and operators.

## Webhooks

Fires when a Trello card is created.

```ts theme={null}
trello({
    webhookHooks: {
        cards: {
            cardCreated: {
                after: async (ctx, result) => {
                    console.log('Trello card created:', result.data?.action.data.card?.id);
                }
            },
        },
    },
})
```

Mount your framework handler once (see [Frameworks](/frameworks/next)), then point the provider at that URL. Full event list: [Webhooks](/plugins/trello/webhooks). Concepts: [Webhooks](/concepts/webhooks), [Hooks](/concepts/hooks).
