What is web scraping and how does it work
Web scraping, also known as web data extraction, is the process of retrieving available data on public websites so that you or your business can gain valuable insight.
This can be done by writing your own web scraper, which requires high-level coding knowledge and plenty of time, or you can use a pre-built web scraper that can be easily integrated with existing software, just like WebScrapingAPI.
Our product works as a service you don’t have to download, install, or set it up, and it comes with lots of benefits. When using WebScrapingAPI the process will be smooth and simple. Just 3 logical steps:
1. Create a WebScrapingAPI account
This one is quite easy. As mentioned before, you will receive 1000 API calls for free when creating the account, because we want you to enjoy our process and convince yourself about the benefits of using it.
2. Log in and go to the dashboard
Here you will get your API key that is going to be used to authenticate with the API. Make sure you don’t share the key online, as it’s meant to be your unique login credential.
You can check for real-time results using the “API Playground”. After inserting the URL of the page you want to scrape, you will have different options to choose from, so that your scraping is personalized to your needs. You can choose to render the JS or not, same for keeping the headers, the device from which you want to scrape, the proxy type, or even the country.
At this point, the playground also shows the code sample of your request in different programming languages like Python, Ruby, Curl, NET., PHP, Java, and even Golang, in case you wish to do it yourself.
Also, WebScrapingAPI retrieves the whole HTML data of the website you wish to scrape into JSON format, afterward it’s easy to restructure and analyze the data.
3. Integrate WebScrapingAPI with your application
On the documentation page, you will find detailed usage guides along with code examples in different programming languages to help you better understand the process.
You have now successfully scraped a webpage and have all the necessary data by your side.

The challenges of web scraping and how to overcome them
While scraping the online environment, there are some challenges that can arise. Most of them have the same purpose: to block your activity so that you stop scraping website pages.
But there is hope. If you use WebScrapingAPI you can just enjoy the results and we will take care of problems like:
Many webmasters use anti-bot protection to prevent DoS attacks or to discourage web scraping. If you make plenty of requests in a short time frame or use known proxy IPs, there’s a good chance you’ll get blocked before extracting all the needed data.
WebScrapingAPI uses rotating proxies to prevent that. With each request, the API uses a different IP from its pool of 100+ million datacenter, mobile, and residential proxies across hundreds of ISPs and regions. With such a large proxy pool, you can also choose an IP location suitable for region-locked content.
Besides cookies, many websites use special functions to gather data from visitors and create a profile by which to identify them. That is known as fingerprinting and it can be a major challenge for web scrapers since they are often blocked once identified.
WebScrapingAPI constantly changes your perceived details so websites see the different requests you send as coming from different visitors. Users can set their own custom headers to get customized results, while the anti-fingerprinting functions are automatic.
Another way to prevent bots from doing damage to a website is to use captchas, which many websites do. If a user is acting “suspicious”, like making too many requests, they’ll receive a captcha to solve. In theory, this should be impossible for a bot. The best way to get past captchas is to not run into them in the first place.
WebScrapingAPI automatically rotates proxies, randomizes wait time, user-agent, browser, and device details to circumvent captchas entirely.
All these features will help you save a lot of time while doing web scraping. It will solve problems other products can’t, by using the latest technologies available, powered by Amazon Web Services and with millions of API requests served every month.
