Check subscriber status from 3rd-party site

I use aMember to manage subscribers to a Wordpress site. I licence some of my content to a third-party site, but the content should only be visible on the third party site if its users have an active subscription to my site.

How can the third-party site check if a visitor has an active subscription to my aMember installation? I have looked at the online help and documentation and I think this can be achieved using REST API but am unsure. If REST API is the appropriate method, are there any examples of how to check subscription status from a third-party site I can look at?

Thanks

Thanks for this reply Caesar. The 3rd-party site won't handle my site's log-in details, they want to direct users to a landing page on my site which checks if the user is signed in and if not the user then logs in. Once a subscription is verified I then need to make a server-to-server call to the 3rd-party site to pass over relevant information including user information in particular subscription status and expiration date.

It doesn't seem to me like a simple thing to set up, so I am wondering whether I shouldn't find a coder to help with this.

Thanks I will do that.
