Can I backfill missing historical data?

Yes.

Yes. For cloud-API providers, missing past data can be retroactively pulled using the historical data request endpoints (e.g. /v2/daily, /v2/activity) with the date range and to_webhook=true to replay it into your destination.

Gaps are usually caused by:

• Temporary webhook-delivery interruptions on the platform or provider side.

• Providers occasionally never sending a webhook for an event.

Report multi-day gaps so a backfill can be run for affected users.
