Managed cards

Managed card balance adjustment

Sent when a card's balance is adjusted outside the normal authorization and settlement flow — most often when the remaining balance of a lost or stolen card is moved onto its replacement.

Changes

Webhooks have no change history: a webhook is keyed by its event name rather than a path and method, so no recorded change can name it.
