Contact Deletion through REST API - POST error

Question

I am using the below code to delete contacts. I am getting a HTTP post error. Not able to find any obvious error. Would appreciate any insight from the community.

This is the error message I am getting:

"message":"An error occurred when attempting to evaluate a HTTPPost function call. See inner exception for details.","description":"ExactTarget.OMM.FunctionExecutionException: An error occurred when attempting to evaluate a HTTPPost function call. See inner exception for details.\r\n Error Code: OMM_FUNC_EXEC_ERROR\r\n - from Jint --> \r\n\r\n --- inner exception 1---\r\n\r\nSystem.Net.WebException: The remote server returned an error: (596). - from System\r\n\r\n\r\n\r\n"}

This is my code:

var url = "https://mysfmc-6384.rest.marketingcloudapis.com";
          url += "/v1/contacts/actions/delete?type=listReference";
          var DE_KEY="my_de_key";
          var headerNames = ["Authorization"];
          var headerValues = ["Bearer " + accessToken];
          var contentType = "application/json";
          var payload = '{';
          payload += ' "deleteOperationType": "ContactAndAttributes",';
          payload += ' "targetList": {';
          payload += '   "listType": {';
          payload += '     "listTypeID": 3';
          payload += '   },';
          payload += '   "listKey": "' + DE_KEY  + '"';
          payload += ' },';
          payload += ' "deleteListWhenCompleted": false,';
          payload += ' "deleteListContentsWhenCompleted": true';
          payload += '}';
          Platform.Response.Write(payload);
         result = HTTP.Post(url, contentType, payload, headerNames, headerValues);
          result = Stringify(result).replace(/[\n\r]/g, '');
          Platform.Response.Write(result);
          Platform.Response.Write("Test");

Looks like you do not have the correct url.

Try:

/contacts/v1/contacts/actions/delete?type=listReference

Instead of:

/v1/contacts/actions/delete?type=listReference
