I'm trying to use the REST API in HCM to create an benefits element entry (specifically a 401k contribution). I'm testing this out in postman from the documentation here: REST API for Oracle HCM Cloud - Create an element entry . However, I'm still getting errors. The API tells me it needs a "RelationshipId", though doesn't accept this value in the body, and also doesn't let me set PayrollRelationshipNumber. Has anyone successfully loaded element entries into HCM with the API?
