Allow External System To Use The Same Login Details?

I am trying to figure out a way to allow an external system to control or be controlled by the same account details.

So I would like our users to be able to sign into the shopping cart and an external forum script with the same details without having to create two accounts.

Is this possible, and where is a good place to start?


At first please check CS-Cart Auth API:

Auth — CS-Cart 4.1.x documentation

If you need any help with the integration with 3rd party system, please contact us at

Thank you.

Thanks this gave me more insight into the API, but not quite what I need.

I want a way to have a login form on another page that the user can enter their details and login. I also want to be able to check and see if the user is logged in.

I figured out how cs-cart generates the cookie, but not sure if I use the cookie id with a connection into the database. Is there a better way of doing this?

Did you ever get this working? I have implemented the widget mode and I need a way to pass through the logged in user from the main site to CS-Cart and login the corresponding user account in the CS Database.
