# Events

The SDK Provider emits events during its life Flow to provide information during use.

## Usage example

```jsx
<facephi-sdk-provider
    apikey={process.env.FACEPHI_SDK_APIKEY}
    onEmitData={(event) => {
        console.log('DATA:', event.detail);
    }}
    onEmitError={(event) => {
        console.error('ERROR:', event.detail);
    }}
>
    (...)
</facephi-sdk-provider>
```
