# Backfill up to a Year of Historical Data from API Connectors

For supported API connectors, ingest up to one year of continuous historical data per request without managing repeated 30-day retrievals. Automated backfill manages data chunking and provider rate limits in the background, helping prepare data for year-over-year analysis and machine learning models. Available date ranges vary by provider.

**How:** In Marketing Intelligence, on the Data Management tab, locate the data pipeline row. From the dropdown menu, click **Reprocess**, and then select the date range.
