  title: Sift Chargeback Label And Rescore
  summary: Record a chargeback, label the user as fraudulent, and force a fresh score.
  description: >-
    The fraud-feedback loop that keeps Sift's models sharp. When a chargeback
    arrives the workflow records a $chargeback event, applies a fraudulent label
    to the user as a payment-abuse training signal, forces a fresh Sift Score
    computation so downstream systems see the updated risk immediately, and reads
    the recomputed score back. The Labels API is deprecated in favor of Decisions
    for new integrations but remains supported for backfill, which is the
    historical-bookkeeping purpose modeled here. Every request is inlined.
