API to POST to SAP | RAP | SEGW | if_http_extension~handle_request

[Sathya_Gunasekaran]

Hello experts,

We have a requirement for a non-SAP cloud system to POST a simple JSON paylod to SAP S/4 and the schema is something similar to

{
	"event": "initiated",
	"date": "2021-10-12T19:26:01Z",
	"data": {
		"id": "MMM12345678",
		"amount": "100",
		"currency": "GBP",
		"payment_method": {
			"type": "card"
		},
		"fields": {
			"reference": "REF-1234",
			"id": "123456789"
		},
		"payer": {
			"first_name": "TEST",
			"last_name": "TESTL",
			"email": "Test.Test@Test.com"
		}
	}
}

No GET needed. What is the best way to handle this? REST handler class or an ODATA  service using SEGW or ODATA service using RAP. If RAP is the reommended way, how to define the nested json structure as custom entity for the above payload please?

Thank you.

Sathya

root:-

@AccessControl.authorizationCheck: #NOT_REQUIRED
@EndUserText.label: 'Event Root'
@ObjectModel.compositionRoot: true
define view entity ZI_Event
  as select from zevent
{
  key id    as EventId,
      event,
      @ObjectModel.association.type: [#TO_COMPOSITION_CHILD]
      _Payer
}

Thanks

and create a z table called zevent?

[ArunJacob]

yes I hope for storing(Post) , a custom table required Sathya

Thanks Arun. No, I have to write logic/use BAPIs to update some standard tables. The JSON payload doesn't link to any table in the DB. It will be a lot tidier with SEGW/HTTP Handler. 😞
