Steps
Register an OAuth application at universe.com/oauth/applications
Complete the OAuth 2.0 authorization code or client credentials flow against the Universe OAuth endpoints, requesting the public scope
Use the returned access token as a Bearer header on REST calls, or query the same data via the GraphQL endpoint
Call the guestlists resource for an event to retrieve attendee and ticket-holder records
Retrieve orders for the event to reconcile purchases against the guestlist
Known gotchas
Universe's API is publicly self-serve (no special partner approval required to create an OAuth app), unlike some other ticketing platforms owned by the same parent company — don't assume the same access model applies elsewhere in that corporate family
Both a REST reference and a GraphQL endpoint (GraphiQL explorer) are available; pick one consistently rather than mixing paradigms in the same integration
No dedicated webhook documentation was found for real-time updates — plan on polling guestlist/order endpoints for change detection
