What is ZenRows?
ZenRows is a web scraping API that helps users extract data from websites efficiently. It handles challenges like dynamic content, captchas, and bot protections, making it easier to retrieve structured information from the web.
Understanding the 400 - Bad Request Error
If you encounter a 400 - Bad Request error when using ZenRows, it usually means that the webpage you are trying to scrape has strong security measures in place. These measures may include:
JavaScript rendering requirements
Bot detection and captchas
IP blocking or rate limiting
How to Fix This Error
To bypass these security restrictions, ZenRows provides options like JavaScript Rendering and Premium Proxies. Enabling these features helps simulate a real browser session, making it less likely for the website to block your request.
Workaround: Enable JavaScript Rendering and Premium Proxies
Go to the Data Editor in Glide.
Add a URL Column where you store the webpage link.
Create a new ZenRows - Get Page Content column.
Target the URL Column and enable both:
JavaScript Rendering (to process pages that require JavaScript execution)
Premium Proxies (to avoid IP bans and improve request success rate)
Why This Works
JavaScript Rendering allows ZenRows to execute scripts just like a real user’s browser, ensuring that dynamically loaded content is accessible.
Premium Proxies help distribute requests across different IPs, reducing the risk of getting blocked by the target website.
By following these steps, you can effectively scrape data from websites with stronger security measures and avoid the 400 - Bad Request error.
