What add-ons are
Optional line items attached to the same registration as tickets — not separate events.
Common uses: parking, return coach, meal packages, merch pre-orders, donation upsells.
Create an add-on
API and dashboard support ticketing_addons per event:
- Name, description, price
max_per_ticket— how many per ticket in the basketquantity_total— optional global cap (e.g. 50 coach seats)
Fans see checkboxes on the public event page; totals include add-ons before Stripe Checkout.
Payment plans
Add-ons are typically charged in full on the first instalment even when tickets use a payment plan.
Transport
For a single coach route, an add-on is usually simpler than a separate transport listing. See Coach & transport tickets for the full decision guide.
