Alert Transaction Linked Event

The Alert Transaction Linked webhook is available exclusively for Chargeflow Alerts customers. It notifies your system in real time whenever Chargeflow successfully matches a pre-chargeback alert to a transaction in your payment processor. When this occurs, the webhook sends an HTTP POST request to your configured endpoint containing the alert ID and the matched transaction ID.

Merchants can use this webhook to:

  • Trigger workflows that depend on having transaction-level data (e.g., adding customer tags, cancelling subscriptions, etc.).
  • Ingest alert-transaction data into internal systems for logging, monitoring, or case management.

The webhook payload includes the alert ID, the matched transaction ID, and basic metadata about the alert. For full alert details — which may evolve over time (e.g., outcome) — you can call the Get Alert by ID endpoint.
