API with my own endpoint while keeping the standard API provided by the sandbox,

[eco_kuman]

i use s4/Hana Cloud.I would like to establish API integration with an external system using my own data registered in SAP, rather than using the sandbox environment. I want to keep the API specifications for the "supplier invoice" API, but only change the host, port, and retrieved data. My understanding is that I need to configure custom host, port, and authentication credentials. Could you please provide me with any available documentation or tutorials that summarize the steps to achieve this?
