Build an event registration site with AI: capacity, tickets and check-in

A worked example: where the task becomes difficult

A fictional community workshop has forty seats, two ticket categories and an optional accessibility request. Some registrations are pending payment, others are complimentary. The organizer needs to know confirmed attendance, not just form submissions. Begin with a free controlled event and fake attendees. Separate information needed for the ticket from sensitive accommodation details, which should have a restricted handling process and a retention decision.

Decisions to make before implementation

Choose whether capacity is shared across ticket categories or allocated independently. Define waitlist promotion and what happens when a pending reservation expires. Ticket references should not expose an attendee’s complete contact record. Check-in can mark attendance but must not silently increase capacity or reuse a ticket already admitted. If tickets are transferable, decide how the old credential becomes invalid.

A practical sequence for the work

Use the sequence below as a task boundary, not as a claim that the example has been executed. Work with approved inputs and the project’s actual architecture. If a required integration or permission is unavailable, keep that stage visibly incomplete rather than generating a plausible substitute result.

• Write capacity and registration states with examples for each ticket type.
• Implement registration acceptance and cancellation against controlled attendee records.
• Generate a ticket reference and a restricted organizer check-in view.
• Rehearse the arrival flow with poor connectivity and repeated scans.

A detailed brief you can adapt for your agent

Replace the illustrative context with your approved facts and controlled inputs. Keep the stated boundaries when adapting the brief. The expected deliverable matters more than a particular tool name: ask for an explanation grounded in the inspected material and evidence for the requested outcome.

Build one controlled event registration journey for forty seats. Model accepted, pending, cancelled and checked-in states. Do not encode private attendee details in the public ticket. Add a duplicate-scan check and a capacity test. Preserve a manual check-in fallback and mark any payment processing as unimplemented until its trusted integration is configured.

Failure modes that an attractive preview can hide

A generated QR code can merely encode an email address without proving registration. Treat the scan as a lookup into trusted ticket state. Test repeated scans, cancelled registrations and screenshots of old tickets. Avoid collecting dates of birth or personal documents merely because a template includes those fields. Every collected field adds handling work for the organizer.

Acceptance checks and the evidence to retain

Provide the capacity policy, registration transitions, ticket lookup design and organizer rehearsal results. Keep attendee data access narrower than the public event page.
