ɃU Gateway
Keep your website. Take ticket money through ɃU.
Built like Paystack. Your other site stores a ɃU secret key, starts a payment, redirects the guest, then verifies. Paystack stays inside ɃU. Tickets land in ɃU Access.
Secret key
sk_live_ on your server. POST initialize. Same pattern as Paystack.
Public key
pk_live_ in a widget or hosted checkout. Never charges by itself.
Verify + webhooks
GET verify/:reference. ticket.purchased signed with X-BU-Signature.
