When we upload approximately 1000 contacts, how long does it take to be served by the HubSpot API?

- Is there an exact time frame which we need to wait before it is served by the HubSpot API?

Thanks

Hi, @howardmarxb.

Apologies for the delayed response.

I would expect the contact records to be available within a couple seconds, however the exact time it takes may be affected by the number of properties being set or updated.

To get a more accurate estimate, you could create a `contact.creation` [webhook subscription](https://developers.hubspot.com/docs/methods/webhooks/webhooks-overview), create one thousand example contacts, and monitor to see when HubSpot’s Webhooks API notifies you of the creation events.
