Tips and FAQ

If you look at the API docs for SAP S/4 HANA Cloud, you'll notice that the /customers resource does not include a POST method. This is because you create customers using POST /business-partners. Follow the steps below to create a customer.

1. Call the POST /business-partners endpoint with this body (replacing values with your own):

   
   {
     "BusinessPartnerCategory": "1",
     "BusinessPartnerGrouping": "0001",
     "FirstName": "WeMake",
     "LastName": "Integrations",
     "BusinessPartnerFullName": "WeMake Integrations",
     "CorrespondenceLanguage": "EN",
     "IsMale" : true,
     "to_BusinessPartnerAddress": [
       {
         "Country": "DE",
         "StreetName": "Dietmar-Hopp-Allee 16",
         "PostalCode": "69190",
         "CityName": "Walldorf",
         "to_AddressUsage": [
           {
             "AddressUsage": "XXDEFAULT"
           }
         ]
       }
     ],
     "to_BusinessPartnerTax": [
       {
         "BPTaxType": "DE0",
         "BPTaxNumber": "DE012345678"
       }
     ],
     "to_BusinessPartnerRole": {
       "results": [
         {
           "BusinessPartnerRole": "FLCU01"
         }
       ]
     }
   }
   
   		

2. In the response, find BusinessPartner, and copy the value (the Business Partner id).
3.  Call the GET/business-partners/{id}?expand=to_Customer endpoint, using the BusinessPartner value from the previous step as the id.
4. In the response, find Customer (nested in to_Customer), and copy the value (the Customer id).
5. Call the GET/customer/{id} endpoint, using the Customer value from the previous step as the id.
6. Use PATCH/customers/{id} to add details to the customer.

In GET/business-partners/{id} and GET/customers/{id} requests, you can include an expand query parameter to get more information about certain nested objects. For example, when you make a GET/business-partners/{id}, the response includes the following object which you can expand to view more.

 
  "to_Customer": {
    "__deferred": {
      "uri": "http://107.23.145.245:50000/sap/opu/odata/sap/API_BUSINESS_PARTNER/A_BusinessPartner('122')/to_Customer"
    }
  }

Expand a Single Object

To expand the nested object, add the expand query parameter: GET/business-partners/{id}/expand=to_Customer. 

The response includes the expanded object:

 
  "to_Customer": {
    "NielsenRegion": "",
    "CreationDate": "1529020800000",
    "IndustryCode2": "",
    "CreatedByUser": "RAMANA",
    "Customer": "57",
    "IndustryCode1": "",
    "to_CustomerCompany": {
      "__deferred": {
        "uri": "http://107.23.145.245:50000/sap/opu/odata/sap/API_BUSINESS_PARTNER/A_Customer('57')/to_CustomerCompany"
      }
    }

Expand a Sub-object

Notice that the to_Customer includes the to_CustomerCompany that can also be expanded. You can expand sub-objects with a request like GET/business-partners/{id}/expand=to_Customer/to_CustomerCompany.

Expand Multiple Objects

Expand multiple objects by including a comma-separated list in the query parameter. Do not add spaces between commas. For example, GET/business-partners/{id}/expand=to_Customer,to_Supplier.
