As an AI screening provider or assessment platform, you typically only need current and up-to-date candidate applications, not historical data that accumulates in ATS systems over time. Kombo’s upstream filtering feature allows you to significantly reduce sync times and data processing overhead by filtering candidates and applications to only those updated within a specific timeframe. This solution is a “best effort” solution. We do not guarantee that all data will match the filters exactly. Not all integrations support the nessesary filtering granularity. If you are building workflows on your side that rely on specific filters, please filter on our API or during processing in your system as well.

​
Performance benefits

Upstream filtering provides substantial performance improvements:
  • Faster sync times: Dramatically reduce the time needed to synchronize data from large ATS systems
  • Reduced data volume: Process only relevant, recent applications instead of entire historical datasets
  • Improved reliability: Smaller datasets reduce the likelihood of sync timeouts and failures
This is especially valuable when working with enterprise customers whose ATS systems may contain thousands of historical applications that are irrelevant for current assessment workflows.

​
Filtering options

You can configure upstream filtering using two approaches:

​
Cutoff date

Set a specific date after which candidates and applications should be synchronized. Only records updated after this date will be included in syncs. Use case: You want to start fresh from a specific point in time, ignoring all historical data before a certain date.

​
Rolling duration

Specify a number of days to look back from the current date. Only candidates and applications updated within this rolling window will be synchronized. Use case: You want to maintain a consistent window of recent data (e.g., always sync applications with activities from the last 90 days).

​
Configuration

Upstream filtering configuration Navigate to your integration settings and configure the sync mode to “Sync all candidates” with upstream filtering enabled.
Upstream filtering is not compatible with the Sync created candidates only sync mode.

Implementation considerations

When using upstream filtering:
  • Only filtered data: We apply the filters while syncing data from the ATS. If you modify the filter, previously synced data outside the filter window will get deleted from our system after 14 days.
  • Filter changes: Adjusting filter parameters may cause some applications to fall outside the sync scope.
  • Integration compatibility: Most ATS integrations support upstream filtering, though the exact implementation may vary
  • Webhook compatibility: Upstream filters only apply to get recently changed data, so anything that would trigger a webhook on the ATS, will usually bring back the candidate and application to be synced as well.
