Adyen is the primary payment processor used by Apareé clients in EMEA and APAC, and a common choice for operators running cross-border portfolios. The integration sits behind the payment wrapper, exposing the same operations Stripe exposes, with Adyen's settlement, local payment methods, and regulatory posture underneath.

The integration consumes Adyen's unified commerce model so the same operating-layer behavior — charging an amenity fee, holding a deposit, issuing a refund — works across every market the building operates in. Local payment methods (SEPA, iDEAL, Bancontact, regional card schemes) are supported without per-method consumer code; the wrapper normalizes them into the same charge / hold / release / refund / reconcile contract.

The integration also handles the regulatory side. SCA challenges, 3DS flows, and country-specific reporting are managed at the wrapper, not exposed to the consumers. The behavioral standard scores the financial side of the resident experience — refunds within the window, holds released on schedule, statements arriving when they should — and the integration is what makes those guarantees enforceable across processors.
