Short answer
HubSpot's v1 lists migration guide: to retrieve recently updated records, filter by lastmodifieddate with the search API instead of the v1 recent endpoints. Search returns at most 10,000 results per query, so sync in time windows.
1. The request
POST /crm/v3/objects/contacts/search
{ "filterGroups": [ { "filters": [ { "propertyName": "lastmodifieddate", "operator": "GTE", "value": "2026-10-01T00:00:00Z" } ] } ],
"sorts": [ { "propertyName": "lastmodifieddate", "direction": "DESCENDING" } ] }2. Limits
