cURL, which stands for client URL, is used in command lines or scripts to transfer data to and from a server.

On PYPROXY, we use cURL to test whether your device can be connected to our proxies. However, some of our customers may find it shows this error when they try to use the command:

'curl' is not recognized as an internal or external command, operable program or batch file

This is because you haven’t installed cURL in your device. How to install and run cURL? Follow the steps and you’ll find out.

Step 1. Download cURL from https://curl.se/windows/ remember to choose the one which matched the type of your device.

Step 2. Find the "bin" folder and open it, Copy the curl executable file(curl.exe) to this folder: C:\Windows\System32

Step 3. Press Win+R, input cmd, then press Enter.

Step 4. Input curl --help to test whether you can use the command.

It means you can use the command now if it shows you a list like the one above.

Now you can use the curl command to test whether your device can be connected to our proxies. Test tutorial.
