Hubspot Webhooks API: Object ID same as contactid?

Hi! After looking through documentation, the Hubspot Webhooks API call seems to return data in the following form.

[{"objectId": [objectId],"propertyName": "lifecyclestage","propertyValue": "subscriber","changeSource": "ACADEMY","eventId": 3816279340,"subscriptionId": 25,"portalId": [portalId],"appId": 1160452,"occurredAt": 1462216307945,"eventType": "contact.propertyChange","attemptNumber": 0},...]

Here, what is the ObjectId? If the returned object is the contact, is the ObjectId the same as the ContactId?

Thank you!

Hello @exuRTC
the objectId in the HubSpot Webhooks API call is the same as the contactId if the returned object is a contact. The objectId is a unique identifier for the object that was created, changed, or deleted. For contacts, the objectId is the contact ID.
