There is a large pool of eCommerce development platforms available in the digital market, but Shopify is the most preferred platform for online store development across the world. With 4.12 million users worldwide, Shopify is ruling the eCommerce industry in this crowded digital market. The number is massively increasing, so the different demands increase.

Creating a high-performing Shopify store with a lucrative design is not sufficient for store owners; they have to offer advanced features and convenient payment providers that offer a smooth user experience. If one already owns a payment gateway app but it is not available on Shopify, developing a Shopify payment gateway extension is a generous opportunity to leverage the broad Shopify audience.

What is Shopify Payment Gateway Extension?


Shopify payment gateway extension enables store owners to get personalized payment processing services for their customers. When payment providers publish their payment gateway app on Shopify, it becomes a public Shopify payment app. So, Shopify merchants who are looking to get customized payment providers for their stores can install that payment gateway extension to integrate their desired payment processing app easily.

There are mainly 2 types of Shopify payment gateway apps:

1) Offsite payment gateway apps

Offsite payment gateway app development allows Shopify merchants to redirect their customers to app-hosted payment websites to complete the payment process with alternative payment methods supported by the payments app.

2) Credit card payment gateway apps

The credit card payment app allows Shopify merchants to let their customers complete the payment process directly on the Shopify website with additional features such as 3DS authentication supported by the payments app.

Shopify store owners can choose any of two depending on their customers’ preferences or personal preferences. Store owners can choose both payment apps to offer their users a range of payment options and a custom-built user experience. Shopify payment gateway development enables payment providers to generate giant revenue by capturing millions of Shopify users.
