Connectors and Applications

To configure the settings of your checkout flows, you must install Connectors and create Applications.

Connectors

Payment Integration Types

The Payment Integration Types available for an Application depend on the Connector. If both types are available, only one can be active at a time, but you can set both up and switch between them as needed.

Payment Connectors

A payment Connector manages the communication between the merchant, Checkout, and the PSP. By using payment Connectors in your Applications, you can provide your customers with payment methods such as credit cards, Google Pay, and PayPal in your checkout flow.

Gift card Connectors BETA

A gift card Connector manages the communication between the merchant, Checkout, and the gift card management system. By using gift card Connectors in your Applications, you can provide your customers with the option of using gift cards as a payment method in your checkout flow.

Applications

An Application lets you set a specific configuration for Checkout, such as country-specific or brand-specific checkout flows.

Based on your business needs, you can create multiple Applications. For example, if you need different settings for different countries, you can create multiple Applications and set up user agreements, Payment Integrations, and other settings for each country.

• Complete Checkout: you can configure the general settings, activate the discount code functionality, add user agreements, and add Payment Integrations.

• Payment Only: you can configure only the general settings and add Payment Integrations.

You can create Applications of different types for the same Project.
