Fill in the blank: To manage rate limits, ___ retrieve only certain contacts as changes happen in HubSpot.

In the HubSpot Data Integration certification, active lists are identified as an effective tool for managing rate limits because they allow an integration to filter and isolate specific segments of data that meet changing criteria, rather than requesting the entire database. By using active lists to define the subset of contacts that need to be synced—such as those whose lifecycle stage was updated in the last 24 hours—developers can significantly reduce the number of API calls required to keep external systems updated. This targeted approach prevents the integration from exhausting HubSpot's burst or daily API rate limits, which often happens when performing broad, unfiltered "GET all" requests to identify incremental changes.
