What you need is the [Private] Hub Register/Registration URL. You have three methods:
Method 1 – From Hub > Members
When you click 👤 Add Member, you can select between "Add directly" and "Invitation." The latter will show you the link to your Hub. From there, you can click 📎 Copy Hub URL.
Method 2 – Directly from the Hub
Inside your Membership.io account, click the three-dot menu icon beside your Hub's name and select Copy Register URL.
Method 3 – From the Hub Registration Page editor
While editing your Hub Registration page, hover over the external preview icon, then click the 📎 clip icon to copy the Hub Registration URL to your clipboard for easy sharing.
