Migrate from Adyen

Adyen to felloh: travel-shaped payments without the enterprise overhead.

Adyen is a strong enterprise gateway but it was not built around the booking. felloh replaces merchantReference workarounds, batched notifications and manual booking matching with a booking-aware ledger that covers payments, refunds, settlement, trust-account evidence and supplier disbursements in one operational record.

Why teams move

Why travel finance teams leave Adyen.

The Adyen stack does its job, but the operational picture it produces is rarely shaped for travel. felloh keeps payments, refunds, settlement, trust evidence and supplier disbursements connected to the same booking record from day one.

No more merchantReference plumbing

Adyen integrations carry the booking reference in merchantReference and rebuild the booking picture in your own code. In felloh, the booking is the record — every payment, refund and settlement attaches to it directly.

Webhooks fire one event at a time

Adyen ships batched notifications that the handler has to unpack. felloh sends individual webhook events with a clean HMAC-SHA256 signature — the handler logic shrinks accordingly.

Tokens look after themselves

Where Adyen needs explicit storedPaymentMethodId management, felloh handles tokenisation automatically — including importing your existing Adyen tokens where scheme portability is supported — and keeps network tokens current through reissue. Capture rates on long-lead bookings stay high without engineering work.

Trust accounts and reporting are native

Adyen has no travel-specific concept of protected funds or ATOL trust treatment. felloh surfaces the trust position against every booking and makes the evidence pack available to trustees, regulators and acquirers without manual extraction.

Concept mapping

Adyen → felloh, side by side.

Most Adyen concepts map directly. A few — bookings, refund authorisation, scheduled payments — are felloh-specific because travel demands them.

Adyen felloh Note
Merchant account Brand / merchant in dashboard Same intent; rolls up cleanly across multiple brands.
Shopper Customer Direct equivalent.
merchantReference booking.reference First-class field on the booking, not a string the merchant has to interpret.
/payments endpoint Payment Links · Ecommerce Sessions · Scheduled Payments Three context-specific tools instead of one unified endpoint.
Manual capture step Automatic capture No two-step authorise/capture by default.
Modifications (refund) Two-stage refund flow Submit + authorise; booking context surfaces inline.
Batch notifications Per-event webhooks One event per HTTP request, HMAC-SHA256 signed.
storedPaymentMethodId Automatic tokenisation No explicit token lifecycle to manage.
What changes

Three shifts that matter day one.

You can map most of Adyen onto felloh directly. These are the differences travel teams actually feel during cutover — and after.

BKG

Bookings replace merchantReference

The booking is a typed record — references, customer, supplier, departure date — that every payment attaches to. The "what booking is this" question goes away.

WHK

Notifications unbatch automatically

Adyen notification handlers built around batch unpacking become single-event handlers. Sign-checking moves from custom logic to standard HMAC-SHA256.

REF

Refunds gain a separation of duties

Adyen modifications run in a single step. felloh splits initiation from approval and surfaces the booking, supplier and policy context to the approver before money moves.

The new shape

A booking, a payment, a refund.

The felloh API is built around the booking. The same record carries the customer, the supplier obligation, the payment trail and the trust position — so finance, customer support and dispute teams all read from one place.

What you gain

What felloh adds that Adyen doesn't.

The travel-specific layer comes built in. ATOL Trust, supplier disbursements, scheduled instalments, two-stage refund authorisation and automatic reconciliation — all live against the same booking record.

Migration plan

A four-phase rollout — run both stacks in parallel.

Cutover is reversible at every step. Move data and flows brand by brand, with parallel processing while you confirm acceptance and settlement timing match your existing baseline.

01

Setup & sandbox

Provision sandbox credentials, wire SDKs into a non-production environment and validate authentication, webhook signing and a sample booking-payment flow.

02

Data migration

Move customer, booking, beneficiary and card-token records across. felloh imports existing card tokens directly from your current acquirer where scheme token-portability is supported, so customers do not need to re-enter card details for live bookings.

03

Flow migration

Move payment collection, refund, settlement and reporting flows brand by brand. Run both stacks in parallel so cutover is reversible at every step.

04

Cutover & decommission

Switch live volume across, monitor acceptance and settlement timing against your existing baseline, then decommission the legacy integration on a schedule that suits the dispute window.
