Discourse Subscriptions not adding subscribers to group

AI-generated summary

originalmarshmello is experiencing issues with setting up a gated Discourse forum for a car club. They have implemented custom code to redirect users not in specific groups to their website for membership purchases via Stripe. However, they encounter webhook errors (email not found and customer not found) when using Stripe buy links, preventing subscription creation and group assignment in Discourse. Testing through the forum URL /s/subscriptions adds members but does not assign them to the correct group. originalmarshmello seeks help to resolve these issues, as the current setup prevents users from accessing the forum. originalmarshmello followed up a week later expressing frustration with the lack of support. palicali also reported experiencing the same issue.

I am setting up a gated discourse forum for a car club, and am running into issues when getting a subscriber access to the site. I currently have some custom code which checks to see if the user is in a group - If not, they are redirected to our website, which has stripe buy links for each of the three memberships we offer.

Here is the code:
<script type="text/discourse-plugin" version="0.8.42"> api.onPageChange((url, title) => { const allowedGroups = ['Lite', 'Member', 'VIP', 'staff']; const isUserInAllowedGroup = api.getCurrentUser().groups.some(group => allowedGroups.includes(group.name)); if (!isUserInAllowedGroup) { window.location.href = "https://centralcoastdriversclub.webflow.io/select-a-plan"; } }); </script>

I have read through the docs on install, set up the three webhook events, and followed everything to a T, but I still cannot get it running smoothly. My first issue is that when I use the product buy links from Stripe on my website, the webhooks seem to give a 422 error with “email not found” for checkout.session.completed and “customer not found” for customer.subscription.updated. This of course does not create a subscription in discourse or add the user to the group. I would ideally like to be able to have a link from my website which takes people to the specific membership they are purchasing.

If I go test it through the forum URL /s/subscriptions, members are added into discourse under the subscriptions tab, but unfortunately are still not added to their respective group. I also noticed that when going through Discourse, it uses a dynamic link which locks the email to the user’s account—interesting!

As you may have pieced together from my code and previous explanation, if the user isn’t added to the proper group, they aren’t able to view the forum as the code redirects them.

I must have missed something, but for the life of me can’t figure it out.
Any help is greatly appreciated—thanks in advance!

It’s been a week, is there no support for this? Surely I am not the only one experiencing this issue…?

I’m having same issue. 9/11/25.
