# Connected Accounts API

The `ConnectedAccounts` class provides methods to manage user connections to external services (toolkits). Connected accounts store authentication tokens and other information needed to access these services.

## Methods

### list(query?)

Lists all connected accounts based on provided filter criteria.

```typescript
// List all connected accounts
const allAccounts = await composio.connectedAccounts.list();

// List accounts for a specific user
const userAccounts = await composio.connectedAccounts.list({
  userIds: ['user123'],
});

// List accounts for a specific toolkit
const githubAccounts = await composio.connectedAccounts.list({
  toolkitSlugs: ['github'],
});
```

**Parameters:**

- `query` (ConnectedAccountListParams): Optional query parameters for filtering connected accounts

**Returns:** Promise<ConnectedAccountListResponse> - A paginated list of connected accounts

**Throws:** ValidationError if the query fails validation against the expected schema


### link(userId, authConfigId, options?)

Creates a Composio Connect Link for a user to connect their account to a given auth config. This method returns an external link which you can use for the user to connect their account through Composio's hosted authentication flow.

```typescript
// Create a connection request and redirect the user to the redirect URL
const connectionRequest = await composio.connectedAccounts.link('user_123', 'auth_config_123');
const redirectUrl = connectionRequest.redirectUrl;
console.log(`Visit: ${redirectUrl} to authenticate your account`);

// Wait for the connection to be established
const connectedAccount = await connectionRequest.waitForConnection();
```

```typescript
// Create a connection request with callback URL
const connectionRequest = await composio.connectedAccounts.link('user_123', 'auth_config_123', {
  callbackUrl: 'https://your-app.com/callback'
});
const redirectUrl = connectionRequest.redirectUrl;
console.log(`Visit: ${redirectUrl} to authenticate your account`);

// Wait for the connection to be established
const connectedAccount = await composio.connectedAccounts.waitForConnection(connectionRequest.id);
```

**Parameters:**

- `userId` (string): The external user ID to create the connected account for
- `authConfigId` (string): The auth config ID to create the connected account for  
- `options` (CreateConnectedAccountLinkOptions): Optional configuration for the link
  - `callbackUrl` (string): The URL to redirect the user to after connecting their account

**Returns:** Promise<ConnectionRequest> - Connection request object with redirect URL

**Throws:** 
- `ValidationError`: If the options fail validation
- `ComposioFailedToCreateConnectedAccountLink`: If the link creation fails

### initiate(userId, authConfigId, options?)

Creates a new connected account by accepting the parameters manually and returns a connection request. Users can then wait for the connection to be established using the `waitForConnection` method.

```typescript
// For OAuth based auth configs (no additional parameters needed)
const oauthConnection = await composio.connectedAccounts.initiate('user_123', 'auth_config_123', {
  callbackUrl: 'https://myapp.com/auth/callback',
});

// For OAuth configs requiring additional parameters (e.g., Zendesk, PostHog)
const zendeskConnection = await composio.connectedAccounts.initiate('user_123', 'zendesk_auth_config', {
  config: AuthScheme.OAuth2({
    subdomain: "yout_subdomain_here"
  })
});

// For API Key based auth configs (requires additional parameters)
const apiKeyConnection = await composio.connectedAccounts.initiate('user_123', 'auth_config_456', {
  config: AuthScheme.ApiKey({
    api_key: 'your_api_key_here',
  }),
});

// For Basic Auth based auth configs (requires username/password)
const basicAuthConnection = await composio.connectedAccounts.initiate(
  'user_123',
  'auth_config_789',
  {
    config: AuthScheme.Basic({
      username: 'your_username',
      password: 'your_password',
    }),
  }
);

// The redirectUrl is where the user should be redirected to authenticate (for OAuth flows)
console.log(oauthConnection.redirectUrl);

// wait for the user to connect the account
const connectedAccount = await oauthConnection.waitForConnection();
```

**Parameters:**

- `userId` (string): User ID of the connected account
- `authConfigId` (string): Auth config ID of the connected account
- `options` (CreateConnectedAccountOptions): Options for creating a new connected account
  - `config`: Connection configuration using AuthScheme helpers
  - `callbackUrl`: URL to redirect after OAuth authentication

**Returns:** Promise<ConnectionRequest> - Connection request object


### waitForConnection(connectedAccountId, timeout?)

Waits for a connection request to complete and become active.

```typescript
// Wait for a connection to complete with default timeout
const connectedAccount = await composio.connectedAccounts.waitForConnection('conn_123abc');

// Wait with a custom timeout of 2 minutes
const connectedAccount = await composio.connectedAccounts.waitForConnection('conn_123abc', 120000);
```

**Parameters:**

- `connectedAccountId` (string): The ID of the connected account to wait for
- `timeout` (number): Maximum time to wait in milliseconds (default: 60 seconds)

**Returns:** Promise<ConnectedAccountRetrieveResponse> - The finalized connected account data

**Throws:**

- `ComposioConnectedAccountNotFoundError`: If the connected account cannot be found
- `ConnectionRequestFailedError`: If the connection enters a failed, expired, or deleted state
- `ConnectionRequestTimeoutError`: If the connection does not complete within the timeout period

### get(nanoid)

   await composio.connectedAccounts.initiate(userId, authConfigId);
   ```

2. **OAuth1** - No additional parameters needed

   ```typescript
   await composio.connectedAccounts.initiate(userId, authConfigId);
   ```

3. **API Key** - Requires API key parameter

   await composio.connectedAccounts.initiate(userId, authConfigId, {
     config: AuthScheme.BearerToken({
       token: 'your_bearer_token',
     }),
   });
   ```

6. **Google Service Account** - Requires credentials JSON

   ```typescript
   await composio.connectedAccounts.initiate(userId, authConfigId, {
     config: AuthScheme.GoogleServiceAccount({

     config: AuthScheme.BasicWithJwt({
       username: 'your_username',
       password: 'your_password',
       jwt: 'your_jwt_token',
     }),
   });
   ```

8. **Bill.com Auth** - Requires session ID and dev key

   ```typescript
   await composio.connectedAccounts.initiate(userId, authConfigId, {
     config: AuthScheme.BillcomAuth({
       sessionId: 'your_session_id',
       devKey: 'your_dev_key',
     }),
   });
   ```

9. **Composio Link** - No additional parameters needed

   ```typescript
   await composio.connectedAccounts.initiate(userId, authConfigId, {
     config: AuthScheme.ComposioLink(),
   });
   ```

10. **Cal.com Auth** - No additional parameters needed

    ```typescript
    await composio.connectedAccounts.initiate(userId, authConfigId, {
      config: AuthScheme.CalcomAuth(),
    });
    ```

11. **Snowflake** - No additional parameters needed

    ```typescript
    await composio.connectedAccounts.initiate(userId, authConfigId, {
      config: AuthScheme.Snowflake(),
    });
    ```

12. **No Auth** - No additional parameters needed
    ```typescript
    await composio.connectedAccounts.initiate(userId, authConfigId, {
      config: AuthScheme.NoAuth(),
    });
    ```

Each helper function returns a properly typed `ConnectionData` object that ensures type safety and validation through Zod schemas. The connection status will be set to:

- `INITIALIZING` for OAuth2, OAuth1, and ComposioLink schemes
- `ACTIVE` for all other schemes

## Multiple Connected Accounts

By default, Composio prevents users from having multiple connected accounts for the same auth configuration. This is to prevent potential conflicts and ensure consistent behavior. However, you can override this behavior if your use case requires multiple connections.

### Default Behavior

When attempting to create a new connected account, if the user already has an active connection for that auth configuration, Composio will throw a `ComposioMultipleConnectedAccountsError`.

```typescript
// This will throw if the user already has a connection
try {
  await composio.connectedAccounts.initiate('user_123', 'auth_config_123');
} catch (error) {
  if (error instanceof ComposioMultipleConnectedAccountsError) {
    console.log('User already has a connected account for this auth config');
  }
}
```

### Allowing Multiple Connections

If your application needs to support multiple connections for the same auth configuration (e.g., connecting to multiple GitHub accounts), you can enable this by passing the `allowMultiple` option:

```typescript
// This will allow creating multiple connections
const connection = await composio.connectedAccounts.initiate('user_123', 'auth_config_123', {
  allowMultiple: true,
});
```

When `allowMultiple` is enabled:

- Multiple active connections are allowed for the same user and auth configuration
- A warning will be logged to help track this behavior
- You'll need to manage these multiple connections appropriately in your application logic

> **Note:** Be cautious when enabling multiple connections as it may require additional handling in your application to manage which connection to use for specific operations.
