API access to attendee tickets, add-ons, and current entitlements

We’re building a lightweight event operations tool that works alongside HeySummit, and we’d love to keep attendee ticket and access information synchronized automatically.

The existing API already gives us helpful attendee, registration, talk, and ticket-catalog data. The piece we haven’t been able to find is the relationship showing which primary ticket, ticket price, and add-ons belong to each attendee.

A read-only endpoint such as the following would be incredibly helpful:

GET /api/v2/events/{event_id}/attendee-entitlements/

Ideally, each ticket or add-on record would include:

• Attendee ID and email

• Primary ticket or add-on designation

• Ticket or add-on ID and title

• Ticket price ID

• Order or purchase-order ID

• Quantity, amount, and currency

• Paid or complimentary status

• Current access status

• Broadcast, replay, in-person, VIP, or other access granted

• Purchase or assignment date

• Upgrade, refund, cancellation, chargeback, or revocation status

• Created and updated timestamps

It would be helpful for primary tickets and add-ons to appear as separate line items. That way, an add-on could be upgraded, refunded, or removed without changing the attendee’s primary ticket tier.

Filtering by attendee, ticket, order, status, and an updated_since timestamp would also make ongoing synchronization much easier.

Right now, keeping this information current requires exporting data from HeySummit and uploading it into another system manually. During an active campaign, registrations, upgrades, add-on purchases, and refunds can change daily. We’d love to automate that synchronization instead of repeating the export-and-upload process each day.

Webhook events for ticket assignments, add-on purchases, upgrades, refunds, cancellations, and access changes would be a wonderful addition as well, although the read-only attendee-to-ticket relationship is our main need.

Thank you for considering it.
