Website Integration question

Hello!

And just to start off, I’m not referring to a WP multi-site integration.

But, I’m having a hard time determining the best course of action for integrating our sites. We have our main website (which relies on Google’s Identity Toolkit), our WP blog, and a Discourse forum. We have a subscription option on our site though, which offers advanced features.

Website: Uses the value of a field within the Datastore to determine if the user has a subscription or not, and grants access to our Pro features accordingly.

Blog: Uses a custom role (Pro) to determine whether or not the user can view the Pro sections of our Blog articles. We use that in combination with the “Hide This” plugin to determine how far into an article a user can read.

Forum: It’s currently set to invite only, as it is a private forum only for Pro users.

So basically, it would go like this: A user purchases our Pro subscription, and then it updates the Datastore, marking them as a Pro user. Our system then creates a Blog user, and marks it as a Pro user. Then, our system sends out an invite to the user for our Pro forums.

All three use separate log-ins though, which is obviously a pain. So I’m looking for a way to integrate them all, and make for a better user experience. I’m NOT the site owner, or even the site Dev, but more of the sites tech guy and/or Quality Assurance lead. I do have access to virtually everything though, so that’s not an issue. Even just being able to integrate 2 of the 3, would be wonderful

I found a WP/Discourse plugin that would have been great, but it doesn’t allow you to set roles for access. So I wouldn’t be able to control who entered our forum with that one. It was on the “soon to come” list for that plugin, but it’s been 9 months since an update, so I expect it won’t be anytime soon, if EVER, that that feature gets added.

So does anyone know of a good WP plugin that could be used for such? I know I’d probably have to integrate the forum separately, with a plugin of it’s own, and that’s fine. I think my main concern though, is finding a plugin that will allow users to sign-in from our main site, but that will also work with the current permissions we have set-up for our Pro users (and without allowing non-Pro users to use the Pro features, ofc).

And also, preferably without relying on the need to code anything else into our site’s code, since the chances are that it would take forever for that to get done.

Any suggestions/ideas would be greatly appreciated! Or even if you know of a good place to ask such a question other then here, that would be awesome as well. As I’m sure there ARE probably much better places to ask such a thing, all things considered. I’m just not really aware of where those places may be.

Thanks,
