# Get Credentials

> Step-by-step instructions for obtaining Trello API credentials.

## Authentication Method

* **[`api_key`](/concepts/api-key)** - Trello API key + token

## API Key Setup

### Step 1: Get Your API Key

1. Log in to [Trello](https://trello.com)
2. Go to [trello.com/app-key](https://trello.com/app-key)
3. Copy your **API Key**

### Step 2: Generate a Token

1. On the same page, click the **Token** link
2. Authorize the app to access your Trello account
3. Copy the generated token

### Step 3: Store Credentials

The plugin uses a combined `key|token` format:

```bash theme={null}
pnpm corsair setup --plugin=trello api_key=your-api-key
```

<Info>
  Trello requires both an API key and a user token. Depending on your setup, you may need to configure the `trelloApiKey` option separately in the plugin options.

## Webhook Setup (Optional)

```bash theme={null}
pnpm corsair setup --plugin=trello webhook_signature=your-webhook-secret
```
