Hello Hubspot Community,

We manage to call periodically hubspot api, via a batch, to get the updated or inserted contacts between 2 dates ( in the past ) expressed with timestamp in seconds:

call n°1 at 12:00:31 =\> GTE 12:00:00, LT: 12:00:30  
call n°2 at 12:01:01 =\> GTE 12:00:30, LT: 12:01:00  
…  
and so on

I would like to know if there is a chance that i miss an updated or inserted contact in my different calls to the web service, for example: a contact was updated at 12:00:29 but not returned in call n°1, if yes, what is the best practices and what can you advise me

Hi [@Anis\_Halayem](https://community.hubspot.com/t5/user/viewprofilepage/user-id/189257) ,

I don’t know of any reason why that record would be excluded/missed if it is within your search criteria. Curious to know more about your project.

[@Mike\_Eastwood](https://community.hubspot.com/t5/user/viewprofilepage/user-id/9259) , do you have any thoughts?

Hi [@Anis\_Halayem](https://community.hubspot.com/t5/user/viewprofilepage/user-id/189257)

As far as I know you can NOT search using the API for specific date ranges.

Could you use a [Webhook](https://legacydocs.hubspot.com/docs/methods/webhooks/webhooks-overview), triggered by a Contact Update, to call you system?

Mike

Hello @dennisedson and [@Mike\_Eastwood](https://community.hubspot.com/t5/user/viewprofilepage/user-id/9259) , and thank you for your concern

As a teammate of Anis, I would like to add some context.

We are using HubSpot Company API and calling the /search endpoint with a filter on hs\_lastmodifieddate.

Like this we are able to retrieve the companies updated between a time frame.

Let imagine that a user, on the HubSpot UI update a company at 10:00:29:999 .  
I guess that the process to handle and store this change will probably take more than 1ms, so this company will be “really updated” at 10:00:30:227.  
In this case, which last modified date will be returned? 10:00:29:999 or 10:00:30:227 or something else?

Hi [@Philip\_JCD](https://community.hubspot.com/t5/user/viewprofilepage/user-id/190672)

While I haven’t tried the API Call you are using – in my experience – [all datetime parameters within HubSpot are in UNIX Time in Microseconds](https://legacydocs.hubspot.com/docs/faq/how-should-timestamps-be-formatted-for-hubspots-apis).

So, my assupltion is that if you give a time in Microseconds it should work predictibly.

But – it’s an API so nothing ever works 100% predictably 100% of the time (UNIX or otherwise).

Have fun

Mike
