## Consent example

Call the `consent()` method to opt-in and opt-out a customer.

:::hint{type="info"}
**Note**
`consent` defaults to `true` if you do not manually set the `consent` field.
:::

```javascript
zaius.consent({
  consent: true,
  identifier_field_name: 'email',
  identifier_value: 'tyler@zaius.com',
  update_reason: '',
  update_ts: 123456789,
  event_data: {}
  });
```

```javascript
zaius.consent({
  consent: false,
  identifier_field_name: 'email',
  identifier_value: 'tyler@zaius.com',
  update_reason: '',
  update_ts: 123474189,

ODP generates events automatically for the purposes of analytics and auditing. The events are structured as follows:

| Event Type | Event Action |
