Shopify plugin
Seamlessly integrate the OPAY payment system with Shopify store by following the Installation guide bellow.
Before you start
Before installing the OPAY payment system on your website, please ensure that the registration form on the OPAY website has been completed. If you have not registered yet, please do so first. After registration, you will receive the necessary credentials via email (Website ID, Signature Password, and User ID), which are required to proceed with the system integration.
Note: Testing the OPAY payment system is not available within the Shopify content management system without a separate setup by the OPAY team. To enable test functionality, please contact us by email [email protected] or by phone +370 611 55554.
Two ways to integrate payment methods
OPAY provides two options for integrating payment methods into your Shopify store:
A single application that includes all available payment methods.
How it works: The customer is first redirected to the OPAY payment page to select the preferred payment method.
Separate applications for each specific payment method.
How it works: The customer is redirected directly to their selected bank, skipping the additional step of choosing the payment method on the OPAY page. This option provides a faster and more seamless checkout experience.You can choose the option that best fits your business needs. The installation steps are identical for both options described below.
Note: Here is a full list of available payment methods; however, your customers will only be able to use the methods specified in your service agreement.

Payment page customization
Customizing the payment page to match your brand’s style can significantly enhance the customer experience. We highly recommend doing so, as a branded payment page builds trust, strengthens the sense of security, and helps reduce cart abandonment.
Customization is quick and easy via the Payment Pages menu in the OPAY self-service portal. You can choose between two design styles, apply your brand color, upload a logo, and preview changes instantly.
