CRM import contacts via API with state "DONE" does not create contacts

Hi!
I ran into a problem with a bulk import of the following:

By using POST https://api.hubapi.com/crm/v3/imports I make imports with CSV files with contacts.
Right after checking :

“state”: “DONE” using GET endpoint I pull these contacts from HubSpot and contacts is NOT there in this moment, when import are done.
But, I can get it after little delay after all it.
How should I be sure when the contacts appear?
Thanks

I would look at the import errors endpoint to confirm that there were no issues.

https://api.hubapi.com/crm/v3/imports/importId/errors?hapikey=YOUR_HUBSPOT_API_KEY

I would anticipate a slight lag in data as the assets are built out and distributed.
