Invitation Relationship Establishment Flowchart

This flowchart outlines the complete business chain from initiating an invitation to successfully establishing a relationship. The process covers invitation initiation (user generates a unique invitation link/code, sets the invitation validity period, and shares it to a third-party platform), user registration (the invitee clicks the link to enter the registration page, the system automatically identifies and includes the inviter's identifier, and the user fills in information to complete account creation), relationship binding (the backend verifies the validity of the invitation code, determines if it is a new user, establishes an invitation association record between the two parties, and updates the inviter's points/rewards), exception handling (invitation code expiration notification, duplicate invitation alerts, self-invitation detection and interception, risk control rule verification), and subsequent actions (inviter receives reward notification, invitee receives new user benefits, invitation progress is tracked, and data statistics are compiled). The diagram also marks key nodes such as relationship activation conditions (invitee's first login/first order completion) and relationship expiration scenarios (invitation code timeout, active unlinking), facilitating an understanding of the complete logic of the invitation mechanism and anti-fraud rules.
