# Track User Consent

> Send consent and/or brand consents.

<Warning>
  **Important:** Please ensure your CMP configuration includes new **Vendor ID 1469** for 1st Party data tracking. Additionally, include **Vendor ID 301** if cookie sync is enabled. [Learn more](/articles/sdks/web-js/configurations/consent-options#shouldcheckzeotapvendorconsent)
</Warning>

The `setConsent` method is used to manage user consent for data collection and processing. This is essential for compliance with privacy regulations like GDPR, CCPA, and other data protection laws.

## Syntax

```javascript theme={null}
import { setConsent } from 'zeo-collect';

setConsent(properties, callback)
```

## Parameters

| Parameter  | Type     | Required | Description                                   |
| ---------- | -------- | -------- | --------------------------------------------- |
| properties | Object   | Yes      | Object of consent properties and their status |
| callback   | Function | Optional | Callback to handle function response          |

## Consent Properties

The consent properties is a object containing key-value pairs. It includes:

### Primary Consent Keys

#### `track` (`boolean`)

* `true`: Allows the SDK to send tracking events (e.g., from `setEventProperties`, page views).
* `false`: Prevents the SDK from sending tracking events.

### Brand Consent Keys

* Any additional key-value pairs in the object.
* Used for tracking consent related to marketing (e.g., `newsletterOptIn`, `personalizationConsent`).
* Passed as query parameters in spl call under `z_p`.
* Do **not** directly control SDK tracking or cookie behavior.

<Note>
  Brand consents are processed and sent to Zeotap independently of the track and cookieSync settings. Even if primary tracking consent is denied, brand consent information can still be transmitted.
</Note>

## Usage Examples

### Example 1: Grant Consent

```javascript theme={null}
import { setConsent } from 'zeo-collect';

setConsent({
    track: true
});
```

### Example 2: Deny Consent

```javascript theme={null}
import { setConsent } from 'zeo-collect';

setConsent({
    track: false
});
```

### Example 3: Passing Brand Consent

```javascript theme={null}
import { setConsent } from 'zeo-collect';

setConsent({
    zeotapVendorConsent: true,
    abcVendorConsent: false
});
```

### Example 4: Passing Brand Consent with primary Consent

```javascript theme={null}
import { setConsent } from 'zeo-collect';

setConsent({
    track: true,
    zeotapVendorConsent: true,
    abcVendorConsent: false
});
```

<Tip>
  **Note**

  In case of, default consent (`opt_out`: `false`)  or CMP consent (`use_consent`: `true` and `check_for_cmp`: `true`) setting primary consent flag will be ignored even if it was sent as part of `setConsent` method
</Tip>

### Passing Consent with Callback

You can also pass consent with a callback function as shown below. The data parameter is an object that contains `status` and `message` which helps to debug the status of the function call.

```javascript theme={null}
import { setConsent } from 'zeo-collect';

setConsent({
    track: true,
    zeotapVendorConsent: true,
    abcVendorConsent: false
}, (data) => {
    // Implement function to handle response
    // {status: "SUCCESS", message: "Consent set successfully"}
});
```

## Best Practices

1. **Request Consent Early**: Ask for consent before collecting any data.

2. **Provide Clear Information**: Explain what each consent category means and how data will be used.

3. **Respect User Choices**: Honor the user's consent decisions and don't repeatedly ask.

4. **Store Consent Locally**: Save consent preferences locally to avoid asking repeatedly.

5. **Allow Easy Updates**: Provide an easy way for users to change their consent preferences.

6. **Default to Denied**: When in doubt, default to denying consent rather than assuming consent.
