Data Pull using filterGroups

I am trying to pull contacts using filterGroups but the request is not pull any data. I know that there have been updates since the last modified date that I am using. Here are the details of the request.

https://api.hubapi.com/crm/v3/objects/contacts/search
Body of request:

{
 "filterGroups": [
 {
 "filters": [
 {
 "propertyName": "hs_lastmodifieddate",
 "operator": "GTE",
 "value": "1720280649000"
 }
 ]
 }
 ],
 "properties": [
 "jobtitle",
 "firstname",
 "lastname"
 ]
 }
}

Question #1: I have tried both hs_lastmodifieddate and lastmodifieddate, and neither of them give me any data. I know there are contacts that have been updated since this date. What’s the secret?
Question #2: Once I do get this to work would a new created contact come back in this data pull?

Hi @SFriesen

Confirming that I get results from the api call when using “lastmodifieddate”.

Just in case you did not notice, it should be a POST method instead of GET

To answer question #2, I created a new contact and tested the api call again, the new contact came back as part of the results.
