Good day everyone,

I'm working on a website that's basically a learning platform open only for existing company clients + their referred family and friends, so basically an entire referral-only based registration system. The courses are entirely free and there's only one membership tier... like I said the only "catch" is that it's only open for existing clients and their loved ones. The list of clients lives in Hubspot where we email them from, which will also be where we'll email them their referral links/codes from to subscribe to the course website.

We've already licensed LearnDash for building the courses, keeping track of user progress, certifying them etc., which came with MemberDash. As you probably know, LearnDash was already clunky on its own and hard to customize as precisely as we want (especially aesthetically for brand guidelines), but the bigger problem was that MemberDash kept causing issues. It was taking over our registration pages and forcing its "Pick your membership tier" interface on them (which like I said doesn't make sense as we only have one tier.) Its media protection features were literally hiding everything up to including the freaking site logo no matter how much I adjusted the settings, its "default" member pages looked like crap. It was just a nuisance, so we've deactivated it.

I've now installed Ultimate Member which has honestly been so much more efficient and streamlined in comparison (in an ideal world we'd have a free addon option where I can fully WYSIWYG customize the widget appearance in elementor to maintain brand guidelines, but hey, CSS exists + LearnDash has been just as much of an annoyance in that regard, so, what else is new. I'm literally just a designer not a frontend dev but learning CSS throughout this has been fun.)

Now as you may have guessed, what remains is to find a way to connect the website to hubspot to 1. Generate referral links/codes from client contacts on Hubspot 2. Allow only those with the links/codes to register (and generate other referrals later for their families if they'd like.) 3. Obviously we'd prefer if it were free at least to start. Idk if it's relevant but the number of clients is not huge (at least relatively); we're talking <4000 contacts.

Any reliable built-in or addon that can do that?

Thank you so much in advance.
