I am creating case record through api record1: { “title” : “case1”, “customerid_contact@odata.bind” : “/contacts(guid)” } record2: { “title” : “case2”, “customerid_account@odata.bind” : “/accounts(guid)” } above two records were successfully created through postman. My question is, while doing programmatically, how we can ensure that we are mapping the customerid with contact or account ?
