'How to integrate a SalesCloud Payment API in flutter?

I have been working on a project and my client has asked me to integrate the SalesCloud Payment API https://docs.salescloud.is/.

I have read their documentation and I understand the concept but I am unable to find any particular code example of integrating this API and I am finding it hard to understand about the API URL.

Any help would be appreciated.
