I have a custom signup page that works great. I’m trying to pass a return url with a parameter for my custom thank you page. The signup and response to my site all work great until I add a parameter to the url and then the API behaves as if I had sent a blank return url and just displays the CC 200 success message and doesn’t perform the redirect. Just be clear this works url=”http://mydomain.com/thank-you-message” this doesn’t url-“http://mydomain.com/thank-you-message?subscriber=3434343” Can anyone confirm if the API rejects parameterized return urls?
