Is it Illegal to Use Proxies on Lazada?
Contrary to what some people will believe, using proxies on Lazada or any other website is not illegal. In fact, proxy usage is legal in most countries around the world except for a few countries like China that criminalize proxy usage.
I will advise you to find out the legality in your region to ascertain whether its usage is allowed or not. Even with it being legal, it can’t be said to be ethical as you are doing it against Lazada's wishes since it does not support proxy usage.
How Do Proxies Help in Scraping Lazada Data?
It might interest you to know that Lazada tracks your IP address and if it gets too many requests in a minute, it would block you as that isn’t normal for humans. Bots are known for that. By using proxies and rotating IPs, you get new IPs after every request or a few requests, this will mean that you will not send too many requests from a single IP address, and as such, you should be able to solve the IP block problem.
Does Lazada Support Scraping of its Data?
Lazada is just like most other e-commerce platforms. They do not support the scraping of their content. Scraping and any other form of automated access are not supported.
This is because aside from extracting their data which they frown on, automated access overwhelms their server and adds to their running cost at no advantage to them. For these reasons, they do not allow scraping and put in place anti-bot systems to detect and block bot traffic.
