POST Requests
Next-Gen Residential Proxies don't only support sending GET requests, but also let you POST to a web endpoint of your choice. This means that you can send data to a target website, which can then make the website return a different result.

Code examples

cURL
Python
PHP
C#
Golang
Java
Node.js
curl -k -v -x ngrp.oxylabs.io:60000 \
-X POST \
-U user:pass1 "https://ip.oxylabs.io" \
-d "Some Content"
