Markdown versions of documentation pages are available by appending `.md` to page URLs; this page is available as [Markdown](https://docs.webscrapingapi.com/webstealthproxy/advanced-proxy-requests/custom-headers.md). # Custom Headers Custom HTTP headers are useful when you want to provide additional information to your request. If your request requires passing custom HTTP headers, all you have to do is to append `WSA-` to your header's name and add them to your request. ### Web Stealth Proxy Custom Headers Examples {% tabs %} {% tab title="cURL" %} {% code overflow="wrap" %} ```bash curl -k -x "http://stealthproxy.webscrapingapi.com:80" -U ":" -X GET "https://httpbin.org/get" --header "WSA-random-header: random" " ``` {% endcode %} {% endtab %} {% tab title="NodeJS" %} 
const axios = require('axios');
const https = require('https');

const instance = axios.create({
  httpsAgent: new https.Agent({  
    rejectUnauthorized: false
  })
});

instance.get('https://httpbin.org/get', {
      proxy: {
          host: 'stealthproxy.webscrapingapi.com',

GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com. ## Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://docs.webscrapingapi.com/webstealthproxy/advanced-proxy-requests/custom-headers.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
