# Headers, Cookies, Method

Web Scraper API maximizes website unblocking efficiency by using headers and cookies predefined by our team.

## Custom headers

If you require the use of your own headers, you can do so by adding the `context:force_headers` parameter and setting it to `true` when submitting a scraping job. Web Scraper API will send your custom headers together with the predefined headers set and then use them to access the website.

#### Code example

```json
{
    "context": [
        {
            "key": "force_headers",
            "value": true
        },
        {
            "key": "headers",
            "value": {
                "Accept-Language": "en-US,en;q=0.5"
            }
        }
    ]
    "source": "universal",
    "url": "https://example.com",
}
```

## Custom cookies

If you require the use of your own cookies, you can do so by adding the `context:force_cookies` parameter and setting it to `true` when submitting a scraping job. Web Scraper API will send your custom cookies together with the predefined cookies set and then use them to access the website.

#### Code example

```json
{
    "context": [
        {
            "key": "force_cookies",
            "value": true
        },
        {
            "key": "cookies",
            "value": [
                {
                    "key": "NID", 
                    "value": "1234567890"
                }
            ]
        },
    ],
    "source": "universal",
    "url": "https://example.com",
}
```

## HTTP Method

`universal` source uses the `GET` HTTP method by default.

If you need to post data to the target website, you must set the HTTP method to `POST` and provide a Base64-encoded `POST` request body.

**Code example**

```json
[
    {
        "key": "http_method",
        "value": "post"
    },
    {
        "key": "content",
        "value": "base64EncodedPOSTBody"
    }
]
```
