Understanding the type Parameter

The type parameter is a key component of the payment process. It specifies the method of payment handling and impacts the behavior of API endpoints and required request fields.

Possible Values for type

• PLATFORM: Payments are handled internally within the system. Requires the accountId parameter to specify the internal account for payment processing.

• CHECKOUT: Payments are processed through an external checkout interface, redirecting users to a payment gateway or external interface.

📘

SDK Integration: @checkout.com/checkout-web-components

• EXTERNAL: Payments are managed by external third-party systems or services. Additional fields, such as someData, may be required to provide integration details.

Note: If accountType is not specified, it defaults to CHECKING.

Proper implementation of the type parameter ensures seamless integration and correct processing for the intended payment method.
