Yes — if a reviewer changes a screening status via the dashboard or the API, and the new status is different from the prior status, a SCREENING: STATUS_UPDATED webhook will fire.
If your webhook endpoint returns a non-200 response or doesn't respond within 10 seconds, Plaid automatically retries delivery for up to 24 hours using exponential backoff — Monitor webhooks are not treated any differently from other Plaid webhooks (see Webhook retries). Plaid does not, however, offer a way to replay webhooks on demand, so if your endpoint is unavailable for longer than this retry window, those events will be lost and your team will need to reconcile missed updates by polling the API.
📌 Note: If your webhook endpoint was down or rejecting events for a period of time, use the /watchlist_screening/individual/list and /watchlist_screening/individual/history/list endpoints to reconstruct the current state of your screenings.
