# Custom Cookies

Custom cookies are an extremely powerful feature of BrowserAPI. For example, they can be successfully used to scrape personalized content on a e-commerce site.

{% hint style="warning" %}
BrowserAPI does not allow the use of custom cookies for authentication purposes.
{% endhint %}

{% hint style="info" %}
Only the following cookies can be overwritten:
{% endhint %}

* ADSHUFFLER
* AWSALB
* AWSALBCORS
* AWSALBTG
* AWSALBTGCORS
* CF\_CLEARANCE
* CONSENT
* CUSTOMER\_CONTEXT
* LANG
* REF
* REMOVAL
* VISITS
* VISIT\_COUNT

Additional cookies may be added per domain by contacting our support.

## Custom Cookies Example

When using JavaScript rendering, custom cookies should be passed in a list in the `cookies` parameter. Each cookie object will have 3 properties: name, value and domain. Here is an example:

{% code overflow="wrap" %}

```json
[{"name":"CUSTOMER_CONTEXT", "value":"{\"customerId\":\"12345\"}", "domain":"httpbin.org"}]
```

{% endcode %}

And this is the URL encoded value from the example above:

{% code overflow="wrap" %}

```
%5B%7B%22name%22%3A%22CUSTOMER_CONTEXT%22%2C%20%22value%22%3A%22%7B%5C%22customerId%5C%22%3A%5C%2212345%5C%22%7D%22%2C%20%22domain%22%3A%22httpbin.org%22%7D%5D
```

{% endcode %}

{% hint style="warning" %} <mark style="color:orange;">**Warning!**</mark> Please make sure that you passed the correct domain value in the cookie objects. We used `"domain":"httpbin.org"` **in the examples below because we want those cookies to be set on the httpbin.org domain**.
