Recently Modified contacts API not returning correct data


Hi ,
A field is modified on all contacts in Hubspot using some workflow. So we need to access all the modified contacts of hubspot.
We are using the following hubspot API.
GET /contacts/v1/lists/recently_updated/contacts/recent

We are passing the vidoffset and timeoffset with each API call and fetching 10 records at a time in one API call.

However , we noticed that the API is not returning contacts after few calls.
Could you please check and let us know the reason for the same.

Please note :We do not wish to use the API for getting all contacts.We would like to use the API for recently modified contacts only and this should return all the contacts in batches as all contacts have been modifiedat a time in HUbspot.
