Triggered when a card is blocked, for example because it was reported stolen or flagged for fraud. A blocked card can no longer be used for transactions. Unlike CardFrozen, blocking is a terminal state: a blocked card is not restored to active state.

Payload Fields

Field	Type	Description
`event`	string	Always `CardBlocked`
`card`	object	Card information; `card.status` is `Blocked`
`reason`	string \| null	Why the card was blocked, for example `Fraud`, `Stolen`, `CustomerRequest`, `DontNeed`
`pan`	string \| null	Deprecated: no longer populated, always `null`
`cvv`	string \| null	Deprecated: no longer populated, always `null`

The deprecated pan and cvv fields are no longer populated and are always null; they will be retired after 2026-10-01.
