The Referral page is public, but you need to sign in to see your own invitation code and link.

Invite and review

Copy your code or invitation link from the page, then open My Invitations to review the records shown for your account. If you have not bound an inviter, the page may offer a way to enter a code. The product checks whether a binding is allowed; an existing binding is displayed rather than replaced. Referral results and any benefits depend on the current program rules and your account state. Use the values shown in the live product.
