Webhooks not receiving

[Integry]

Update webhooks are not firing, I performed a bulk update on a list, updated the city, it was updated but I only received webhooks for only a few of the contacts. I repeated this operation twice, 10 and 15 webhooks were missed respectively.

Hub id: 4865758

App ID: 192434

webhooks that i received:{"id":227741,"event":"contact_updated","date":"2020-06-01T11:45:14.499Z","ts":1591011915,"content":[{"email":"role_3@hs.co","list":{},"attributes":{"LASTNAME":"","FIRSTNAME":"role-3","COUNTRY":"England","COMPANY":"ABC"}}]}

emails for which no webhooks were received: blankenship~annie@canva.co, role_5@hs.co

Hey @Integry ,

I'm not seeing contact records with those emails in the HubSpot account 4865758. Have they been deleted or had their email changed? Additionally, the example body you've included doesn't quite look like what I would expect a HubSpot Webhook to look like: I'd expect something like this:

[
  {
    "eventId": "100",
    "subscriptionId": 170129,
    "portalId": 5731501,
    "occurredAt": 1593027832948,
    "subscriptionType": "contact.propertyChange",
    "attemptNumber": 0,
    "objectId": 123,
    "changeSource": "CRM",
    "propertyName": "city",
    "propertyValue": "sample-value"
  }
]

Can you link to the specific contact records in question?
