IntegrationID not zCRM Contacts ID

IntegrationID not zCRM Contacts ID

Hi, 
I have a field of type integration which is linked to contacts in my zoho crm account.
I can add new entries using the contacts ID from Zoho CRM, however getRecord API provides afterwords a different ID for the field integration

Add a record:
  2. {
  3.     "data": [
  4.         {
  5.             "Integration": "296786000000255011"
  6.         }
  7.     ]
  8. }
getRecord:
  1. {
        "code": 3000,
        "data": {
            "Integration": {
                "display_value": "XXXXXXXXX",
                "ID": "88718000000006007"
            },
            "ID": "88718000000008031",
        }
    }
So how the hell am I able to use the ID that is provided from getRecord to find the contact in Zoho CRM???
