# Custom Headers

If you would like to add custom/additional headers (user agents, cookies, etc.), simply add them as parameters to the request, with the “**wsa-**” prefix.

Only use this feature to get customized results, do not use this feature to avoid blocks. Shifter's Scraping API has a powerful internal engine that takes care of everything for you.

On this page, you will find an example request used to scrape the URL <https://httpbin.org/headers>, which will mirror the headers sent.

### **Custom Headers example**
