Why GoPay Checkout
Redirects cost conversions
A customer who leaves for a payment gateway may not come back. GoPay Checkout changes that.
An uninterrupted purchase
Customers complete their purchase where they started it. There is no need to move to a third-party page.
One touch. Paid.
Apple Pay and Google Pay in one click, with no card details to enter. QR payment as an added bonus.
Your brand, your rules
Colours, logo, font... the checkout adapts to your online store. Trust and conversions grow.
How it works
The payment stays with you. From start to finish.
The customer selects a method. GoPay Checkout displays the right UI directly in the checkout. No redirects. No third-party page.
Step 1
The customer selects a payment method directly in the checkout
The payment block is part of your page, so the customer sees all available methods (card, Apple Pay, Google Pay, QR payment...) as a natural step in the order. They do not go anywhere or leave anything behind.
Step 2
The customer pays using a method they know
GoPay Checkout displays the right UI directly in the checkout. Whether the customer chooses a card, Apple Pay, Google Pay or a QR payment, every method works without a redirect.
Card payment
GoPay displays the payment form directly in the checkout. The customer enters their card details on your website and does not go anywhere else.
Apple / Google Pay
GoPay opens the device’s native dialogue. The customer confirms the payment using Face ID, Touch ID or a PIN. The payment is completed with one touch.
QR payment
GoPay displays a QR code directly in the checkout. The customer scans it in their mobile banking app and the payment is made immediately.
Step 3
The customer completes the payment and stays with you
Confirmation appears immediately on your online store’s website. The customer has not gone anywhere or disappeared onto an external gateway. They bought from you and are ready to buy again.

What is GoPay Checkout?
GoPay Checkout is a payment solution that lets you integrate payment methods directly into your online store’s checkout. The customer does not need to be redirected to an external payment gateway – the entire payment process takes place directly on your website.
How does payment directly in the checkout work?
Using the GoPay JavaScript SDK, you embed the payment block directly into your checkout’s HTML. The customer sees payment methods as a natural step in the order process, chooses their preferred method and completes the payment without leaving your website.
Which payment methods does GoPay Checkout support?
Checkout supports Apple Pay, Google Pay, payment cards (Visa, Mastercard, Maestro) and QR payments. The existing payment gateway remains available through the new API for bank transfers, BNPL and more than 40 other methods. You can tailor the range of payment methods to the needs of your online store.
Does GoPay Checkout work on mobile?
Yes. Checkout is designed mobile-first. It fully supports Apple Pay and Google Pay for fast payments on mobile devices without the need to enter payment details. The payment block is responsive and adapts to the screen size.
Can I customise the appearance of the checkout?
Yes. Through theme configuration, you can set the primary colour, button style, corner radius and other visual elements so that the payment section naturally matches the design of your online store.
How does the integration work?
Integration takes place in three steps: registering a GoPay account and obtaining access keys, adding the JavaScript SDK to your page, and configuring the payment block. The average integration time is 1–3 working days. GoPay provides technical documentation and integration support.
Is a sandbox available?
Yes. GoPay offers a full-featured testing environment (sandbox) free of charge. In the sandbox, you can test the entire payment flow, including all payment methods, without real transactions.
Where can I find the technical documentation?
Complete technical documentation, code samples and integration guides are available at GoPay Payments API v4. The GoPay developer team is also available for direct technical support.
I have an existing integration – do I need a new implementation?
Yes. The new GoPay API v4 differs from the previous version, and switching to payment directly in the checkout requires changes to your implementation. The GoPay team will be happy to help you with the transition.
