Questions About Payment Gateway Integrations in United Kingdom
Can you build a custom plugin for our domestic commercial bank in United Kingdom?
Yes. This is our primary service. If your acquiring bank in United Kingdom provides an API document (such as Mastercard MPGS, CyberSource, or an in-house REST API) and no plugin exists, our developers build an unencrypted, certified plugin tailored to your store.
How does testing and live payment verification work?
We set up and verify all edge cases in your bank’s sandbox/UAT test environment. Once released to staging or production, your authorized team executes a real live test payment on your side. Once the live payment settles into your merchant bank account, the project is signed off and delivered.
Who owns the source code once the integration is complete?
You receive 100% full source code ownership. We provide clean, unencrypted code without any monthly licensing fees, obfuscation, or external dependencies.
