Questions? You're covered.

Payment gateways FAQs.

Still unsure? Email info@web3matrix.com or message us on WhatsApp.

Which payment gateway should I use?
It depends on where you sell, your platform, fees and the payment methods your customers prefer. We help you compare options and set up the one that fits.
Is the checkout secure?
Payments are processed by the gateway, so card details don't touch your server in standard integrations. We use SSL, test every payment flow and follow the gateway's security requirements.
Can you add Apple Pay or Google Pay?
Yes, where your gateway and platform support them. Wallet availability depends on the gateway and your customers' devices.
Can you integrate a gateway into a custom-built site?
Yes. We integrate gateways into WooCommerce, Shopify and custom Laravel applications using the gateway's official APIs.
Do you build stores for international businesses?
Yes. Our team in Dhaka, Bangladesh works with clients in the UK, the USA, Canada and Europe, and welcomes projects from Australia, Japan, South Korea and other markets. We have a UK address in London. Projects run remotely with video calls, shared design reviews and a private staging store.
