Plug-in for my site

[Realname]

Hi,

I'm planning to integrate my platform with your BILLmanager. I want my clients to be automatically redirected to member area after they enter correct user name/password (or get notified that they entered invalid login data).
Can you give me an example of such a plugin?

Hello,

You don't need to write a plug-in, you will need to configure integration of your platform or site with BILLmanager, where your clients will get registered, log in, and make orders.

Please, refer to this article for more details about integration.
