# Available methods

The different methods offered by Landing SDK for the different available configurations are detailed below, with implementation examples.

## callLanding

To launch the Landing, use the method `callLanding`. With this method, the Landing SDK associated with the provided ApiKey will be loaded.

**Example**:

```javascript
const landingSDK = new LandingSDKClient('YOUR_APIKEY');

landingSDK.callLanding();
```

**The client's callback server receives notifica**

This method can receive an object with one or more parameters to configure each execution.

**Example**:

```javascript
lansingSDK.callLanding(options);
```

The available configuration parameters are as follows:

***

### customerId

This identifier will allow you to associate the biometric operation generated in our processes with your client. It can be their email address or an identifier you have for your users.

**Example**:

```javascript
landingSDK.callLanding({
  customerId: 'customer-id@example.com'
})
```

***

### documentNumber

This parameter is optional; you can send your customer's ID number if you have it so that we can compare it with the biometric data obtained by our process.

**Example**:

```javascript
landingSDK.callLanding({
  documentNumber: '1234567A'
})
```

***

### callbackPath

Defines the parameters that will be added to the Callback URL call that we will execute to send the data captured by the biometric process.

**Example**:

```javascript
landingSDK.callLanding({
  callbackPath: 'https://url-callback-example.com/api/onboarding'
})
```

***

### onFinish (iframe)

{% hint style="info" %}
This event is only available in the iFrame implementation.
{% endhint %}

When the Flow ends, the Landing SDK will emit the event `onFinish` to add any additional logic to continue the Flow.

**Example**:

```javascript
landingSDK.callLanding({
  onFinish: () => {
    // Continue process once the onboarding is finished.
    finishOnboarding();
  }
})
```
