We provide development support for an ERP system and need to integrate it with the Clover Payment API, without using Clover devices, as well as creating an app on Clover. Is this possible, and if so, what steps should we follow to achieve this integration for a .NET desktop application?
Additionally, since this is a .NET desktop application, we would like to understand whether it's mandatory to integrate with Clover via an iframe, or if there are alternative methods.
We've done some initial research and understood that the Merchant API and E-Commerce API are likely the best options for this integration. Could you please provide detailed procedures on how to proceed with these APIs?
