Backfill historical data
Import past events from a CSV or another tool without breaking your reports.
A backfill loads events that happened before you installed Tessera. Done carefully, your charts look like Tessera was there from day one.
Before you start
Export events with their original timestamps
Map old event names to your new naming plan
Run the import against a test workspace first
Run the import
Use the batch endpoint with up to 500 events per request. Set the timestamp property on every event, otherwise Tessera uses the time of import.
