How can I deploy Fiori App with POST API call function to Cloud Public edition with excel uploading?

[SAPSupport]

Hello, I'm RAP/Fiori developer and there some errors occur about API calling.

I need to develop Fiori app that uploads datum from excel file and create manufacturing order, using the datum from excel file.But the ways I chose have problems.

API call from Fiori freestyle project succeeded when the API information registered in manifest.json, but ended with deploy error.(abap-deploy)

If the Fiori project includes sap standard API uri in API call logic, call POST API ended with 403 authrization error.

I don't know if this works require the BTP destination, though I don't use SAP Build Wok Zone nor HTML5 Repository. Is the BTP destination required when call SAP standard APIs from Fiori project, and is it possible to deploy by abap-deploy method?

How can I deploy Fiori App with POST API call function to Cloud Public edition? Should I use BTP destination? Or Should I use RAP action? If the RAP action needed, can you show me the use case or logic examples? Or createing Business Object from Custom Business Object app in Cloud Public Edition needed?

It's the first time to develop and deploy in Cloud Public Edition environment, using Fiori project with POST API call. If you suggest some possible solutions in detail, it will be very helpful to succeed the project.
