Question

How do you delete data from a particular Entity using the API? 

Answer

You can use the API to delete data in two different ways:

• Delete in bulk using the BulkOperation task
• Delete a single record by performing the operation UpdateAttribute, DeleteAttribute
  
  For example:

POST {TenantURL}/entities/_update

{
  "objects": {
    "list": [
      "entities/1Kxxxx"
    ]
  },
  "actions": [
    {
      "operationParameters": {
        "attributeURI": "configuration/entityTypes/HCP/attributes/FirstName",
        "sourceTypes": [
          "Reltio",
          "AHA",
          "AMS"
        ]
      },
      "operation": "DeleteAttribute"
    }
  ]
}

Note: All values from SourceTypes will be removed.
