Hi,

I’m using this method https://developers.klaviyo.com/en/v2024-06-15/reference/create_or_update_profile and I’m having a problem when passing null to a field. It does not clear it out as stated in the documentation.

I also tried the latest stable version v2025-01-05, but the results are the same.

Here’s an example of Request and Response.

Request:

{
  "RequestMethod": "POST",
  "RequestUrl": "https://a.klaviyo.com/api/profile-import/",
  "RequestBody": {
    "data": {
      "type": "profile",
      "attributes": { "properties": {}, "organization": null },
      "id": "01JMZ3P5VQQ7778PT1CWMEDB0K"
    }
  }
}

Response:

{
  "ResponseStatusCode": 200,
  "ResponseHeaders": {
  },
  "ResponseBody": {
    "data": {
      "type": "profile",
      "id": "01JMZ3P5VQQ7778PT1CWMEDB0K",
