How to integrate Circle (community forum)

If you would like to have a place for your members to create threaded community discussions around various topics (like a Facebook Group or forum) Circle is a great modern tool to do that with. Your members will also be able to privately message each other.

Your Circle community forum can either live on its own domain (e.g. or be a popup on your website!

If you do not have a website and simply want to charge money for access to your Circle forum, click here for that guide.

MemberSpace has a simple single sign-on (SSO) integration with Circle which means when your members are logged in via MemberSpace on your website, they will automatically be logged into your Circle forum and not have to create a new account of any kind.

We strongly recommend you link to your Circle community URL (e.g. from your website so it opens in a new browser tab. This will be the best user experience for your members. However, if you want to embed your Circle community or use their community widget icon on a page of your website, the page must first be a Member Page. Otherwise, redirect and login issues can occur.
