Category Lockdown This plugin allows you to restrict access to topic pages in a category. Topic titles will still show up in topic lists, search, user activity & digest emails. This is a great way to advertise the activity in a “members-only” category, which may charge for access. Webhook Receiver This plugin allows you to process webhook payloads from other services in Discourse. Currently it’s focused on receiving webhook payloads from Shopify for the management of user groups. It may also work with other webhook payloads out of the box, and we’re open to changes that will add support for other webhook payloads, and webhook payload handling (i.e. outside of managing user groups).
