# Extra Headers

> Source: https://scrape.do/documentation/headers-cookies/extra-headers/

Add headers without replacing default headers

It is a feature that you can use only when there is one or more header parameters that you want to use for the needs of the target website, without breaking the requests we have created for the target website.

After setting the query parameter as `extraHeaders=true`, the header values you will send with the `Sd-**` prefix will be sent to the target website.

**cURL (API mode)**

```bash
curl --location --request GET 'https://api.scrape.do/?token=YOUR_TOKEN&url=https://httpbin.co/headers&extraHeaders=true' \
--header 'sd-Test: TestValue'
```

**Python (API mode)**

```python
import requests
import urllib.parse
token = "YOUR_TOKEN"
targetUrl = urllib.parse.quote("https://httpbin.co/headers")
extraHeaders = "true"
payload = {}
url = "http://api.scrape.do/?token={}&url={}&extraHeaders={}".format(token, targetUrl, extraHeaders)
headers = {
  'sd-Test': 'TestValue'
}
response = requests.request("GET", url, headers=headers, data=payload)
print(response.text)
```

**Node.js (API mode)**

```javascript
const axios = require('axios');
const token = "YOUR_TOKEN";
const targetUrl = encodeURIComponent("https://httpbin.co/headers");
const extraHeaders = "true"
const config = {
    'method': 'GET',
    'url': `https://api.scrape.do/?token=${token}&url=${targetUrl}&extraHeaders=${extraHeaders}`,
    'headers': {
        'sd-Test': 'TestValue',
    }
};
axios(config)
    .then(function (response) {
        console.log(response.data);
    })
    .catch(function (error) {
        console.log(error);
    });
```

**cURL (Proxy mode)**

```bash
curl -k -x "http://YOUR_TOKEN:extraHeaders=true@proxy.scrape.do:8080" 'https://httpbin.co/headers' -v
--header 'sd-Test: TestValue'
```

**Python (Proxy mode)**

```python
import requests
import urllib3
urllib3.disable_warnings(urllib3.exceptions.InsecureRequestWarning)
url = "https://httpbin.co/headers"
token = "YOUR_TOKEN"
proxyModeUrl = "http://{}:extraHeaders=true@proxy.scrape.do:8080".format(token)
headers = {
  'sd-Test': 'TestValue'
}
proxies = {
    "http": proxyModeUrl,
    "https": proxyModeUrl,
}
response = requests.request("GET", url, proxies=proxies, verify=False)
print(response.text)
```

**Node.js (Proxy mode)**

```javascript
const axios = require('axios');
const token = "YOUR_TOKEN";
const targetUrl = "https://httpbin.co/anything";

axios({
    method:"GET",
    url:targetUrl,
    proxy: {
        protocol:'http',
        host: 'proxy.scrape.do',
        port: 8080,
        auth: {
            username: token,
            password: 'extraHeaders=true'
        }
    },
    headers: {
        'sd-Test': 'TestValue',
    }
})
    .then(response => {
        console.log(response.data);
    })
    .catch(error => {
        console.error(error.message);
    });
```
