The details
Why ask the right questions
Understanding how a business takes payment is the first step. Whether a hotel secures a room with a card, a tour operator collects a deposit, or the full amount is charged upfront, each model demands different gateway capabilities. Developers need to map the customer journey from holiday selection to payment confirmation.
Technical integration points
The gateway must communicate with the booking engine to confirm inventory, capture or authorize funds, and update the booking status. Whether the checkout is hosted or embedded determines how data is passed back, and developers should ensure unique references match payments to reservations.
- Confirm if the gateway uses a plugin, custom code, or API calls
- Verify how payment status updates are received without a thank‑you page
Security, compliance and testing
Card data handling, PCI DSS responsibilities, and Strong Customer Authentication requirements depend on the integration method. Developers should demonstrate handling of failed payments, duplicate clicks, and refunds, and provide a plan for testing all scenarios before launch.
- Ask how idempotency is achieved to avoid double charges
- Request a demo of failed‑payment and retry flows

Frequently asked questions
What questions should I ask my developer before adding a payment gateway?
Ask how the payment flow matches your booking process, whether the gateway integrates with your website, which currencies and methods are supported, how failures are handled, who is responsible for security, and what testing will be performed.
Can the payment gateway work with my existing booking engine?
The gateway must be able to send payment status back to your engine, either via a hosted page or an API, and match each transaction to a unique booking reference.
How does the guide suggest handling duplicate payment clicks?
It recommends implementing idempotency, which safely retries the same request without charging the customer twice, and ensuring the system knows when to release inventory.
What security responsibilities remain with the travel business?
Even if the gateway hosts the checkout, the travel business stays responsible for PCI DSS compliance, protecting API keys, and managing any tokenised card data used for later charges.
Do I need to provide extra documents for currency conversion?
The guide does not require additional paperwork; it only advises you to clarify who converts currency, the fees involved, and how refunds are processed in the original payment currency.
