Our [web-scraping.dev/testimonials](https://web-scraping.dev/testimonials) example does exactly that! When the user scrolls to the bottom of the page a javascript trigger is fired that makes a background request to a hidden API. Then, the received results are used to update the visible page HTML. [ ##### How to Scrape Hidden APIs For this example see our beginner-friendly in-depth blog which starts off with devtools network inspector intro and walks through the `/testimonials` example page. ](https://scrapfly.io/blog/posts/how-to-scrape-hidden-apis/)## Why scrape hidden APIs? Hidden APIs are great for web scraping as it's direct access to the website's public data. This means that we have the benefits of: - **Speed** - No need to render the page, execute javascript, and wait for the page to load. - **Stability** - No need to worry about the website's layout changes. - **Consistency** - The data is always in the same format. - **Complexity** - It can be difficult to reverse engineer hidden APIs that are obfuscated or protected. - **Change** - Hidden APIs are not documented and can change at any time. ## Example Exercises By far the most common dynamic data fetching pattern is the "endless paging" pattern which is encountered in many web scraping projects. Take a look at this example exercise of how to scrape endless pagination below 👇 [](https://scrapfly.io/scrapeground/paging/endless) ##### Scrapeground Exercise: Endless Paging Scraping See this in-depth tutorial on Scrapfly Scrapeground full more detailed example of this scraper. This includes examples in different languages and libraries as well as more scenarios. ## Next up - Headless Browsers Reverse engineering hidden APIs can be a difficult process so why not a real web browser for web scraping instead? Let's take a look at that next. [<](https://scrapfly.io/academy/dynamic-scraping "Previous Page") [>](https://scrapfly.io/academy/headless-browsers "Next Page")
