Love the idea of this!
As there is no out-of-the-box solution, implementing it might require a bit of manual work though.
Let’s break this down:
The key challenge here is keeping the memberships in sync across both domains. Here’s a potential game plan:
- When a new member signs up on your main domain, it triggers an action. This could be handled with the “Member Created” trigger on Zapier, or a “member.added” event for a custom webhook.
- The next step is to check if this new member has joined the correct membership tier.
- If they have, create the same member profile on your subdomain. This could be done using the “Create Member” action on Zapier or by sending a POST request to
/ghost/api/admin/members/.
Now, a few important considerations:
- Member management is a two-way street. If a member unsubscribes or cancels their membership on one site, you’d need to ensure they’re removed from the other one too.
- User profile settings would be independent on both sites. This might be a bit confusing for some users, so it’s something to keep in mind.
- Automatic login for a member across both sites isn’t straightforward, unless you’re willing to delve deep and modify the Ghost core. However, I’d advise against that and recommend exploring alternative solutions.
- A word of caution - the Ghost members API isn’t officially documented and could change unexpectedly. The information I have is from this post and this blog article.
I hope this helps. Let me know if anything is unclear!
