How to pass parameters correctly?

Hi, I would like to know how to pass parameters correctly with this plugin.

Let’s say I have an offer link: http://myofferlink.com/?offer_id=123&name=custom_param

And I have created a 301 redirect in my site: /301-redirect/

I would like to pass a param to the “name” variable in my offer link.

Is there a way to do it?

The common case would be to send the request to /301-redirect/?name=custom_param but I don’t think that’s working.

Thanks
