Essentially, this feature allows you to rotate the proxies on your list with each request randomly.
To set this up, simply follow these steps:
Head over to the Rotating Proxy Endpoint page.
There, you'll be able to find all the information you need to configure the rotating proxy endpoint on your end. You can get the Domain Name, Proxy Port, Proxy Username and Proxy Password or use the authorized IP address on your account.
Check out the example configurations in cURL, Python, Java, C#, Node.js, PHP, Ruby, and VB. You can find them under the "See example configurations" section on the Rotating Proxy Endpoint page.
