The SDK, or as we call it, Trio Checkout, is a tool that allows your users to initiate a new payment using OpenFinance in a straightforward manner.

After completing the integration process using Trio Checkout to the front-end of your application, your end users can connect and initiate a new payment with simple and isolated end-to-end security to banks and financial institutions.

All stages of the consent and payment process is managed through the Trio Checkout, from credential validation, authentication, error handling and notifications pertaining to each payment flow.

At the end of the process, the Trio Checkout generates a payment_initiation_document that contains all the information and stages about the initiation. Everything done through Checkout is done simply and without much code needed.
