If this parameter is present, the API takes into account URIs that are specified inside the request. You can use this parameter for both the entities URI and for the attributes URI.

Example 1. Entities URIs in the Request

If this option is present for an entity URI, the API finds this entity and overrides it with attributes in the request. It can be used for inserting new attributes with new/existing crosswalks to entities. If this type of entity doesn't exist, the API returns the EXPLICIT_URI_OF_NON_EXISTING_OBJECT_DEFINED(242) error.

Insert New Attribute With preserverURIs by the Entity URI

POST {tenantUrl}/entities?options=preserveURIs
  
[
  {
    "uri": "entities/0001L5U",
    "type": "configuration/entityTypes/HCP",
    "attributes": {
      "LastName": [
        {
          "value": "LastName 1"
        }
      ]
    },
    "crosswalks": [
      {
        "type": "configuration/sources/FB",
        "value": "entity2"
      }
    ]
  }
]

In this case, the match entity is found by the URI, and the new attribute is inserted into it.

Example 2. Attributes URIs in the Request

URIs of attribute values can be changed during overwrite operation (of an attribute has more than one value and at least one of values were changed). As you can see in the partialOverride option example, the URI of the value of the FirstName attribute was changed after overwrite.

If the preserveURIs option is present for simple or nested attributes, URIs of attribute values for which they were specified in the request JSON will not be changed. This option does not work with reference attributes.

Overwrite With preserveURIs Option for Attributes

POST {tenantUrl}/entities?options=preserveURIs
  
[
  {
    "type": "configuration/entityTypes/HCP",
    "attributes": {
      "FirstName": [
        {
          "value": "Value1New",
          "uri": "entities/0001L5U/attributes/FirstName/1n5QlE"
        }
      ]
    },
    "crosswalks": [
      {
        "type": "configuration/sources/FB",
        "value": "entity1"
      }
    ]
  }
]

In this case, the match entity is found by the crosswalk, and the URI of the attribute value has not changed.
