API v4.1 method login -> File not found

Hi, I am trying to send a login request to the demo environment but receiving an error 404 Not Found. It is running on version 7.13.0. I’ve tested the same request on the demo environment but version 8.2.2 and it works.

The request is:

https://demo.suiteondemand.com/service/v4_1/rest.php?method=login&input_type=JSON&response_type=JSON&rest_data={“user_auth”: {“user_name”: “will”, “password”: “18218139eec55d83cf82679934e5cd75”, “version”:“1” }, “application_name”: “test”}

Status 404 File not found.

Any help is appreciated, thanks!
