Cards

Get a card

Changed on

Retrieve a card by its system-generated id. To display the card's full PAN, CVV, and expiry to the cardholder, request a reveal with POST /cards/{id}/reveal — the card resource itself never carries the reveal URL.

Response

Successful operation

idstring required

System-generated unique card identifier

customerIdstring required

The id of the Customer who holds this card.

platformCardIdstring

Platform-specific card identifier generated by the server.

status'PENDING_KYC' | 'PROCESSING' | 'ACTIVE' | 'FROZEN' | 'CLOSED' required

Lifecycle status of a card.

StatusDescription
PENDING_KYCThe cardholder has not yet completed KYC. Cards in this status cannot transact.
PROCESSINGThe card has been requested and is being provisioned with the issuer.
ACTIVEThe card is live and can authorize transactions.
FROZENThe card is temporarily disabled by the platform. New authorizations are declined with cardDeclinedReason: CARD_NOT_ACTIVE. Existing settlements and refunds continue to reconcile.
CLOSEDThe card is permanently closed. Terminal, irreversible status.
statusReason'ISSUER_REJECTED' | 'CLOSED_BY_PLATFORM' | 'CLOSED_BY_GRID'

Reason a card reached a terminal or non-active status. Present on CLOSED cards, and on cards that fail provisioning before reaching ACTIVE.

ReasonDescription
ISSUER_REJECTEDThe card issuer rejected provisioning during PROCESSING.
CLOSED_BY_PLATFORMThe card was closed via PATCH /cards/{id} (status: CLOSED) by the platform.
CLOSED_BY_GRIDThe card was closed by Grid (e.g. compliance or risk action).
brand'VISA' | 'MASTERCARD'

Card network brand. Read-only — determined by Grid when the card is provisioned with the issuer.

form'VIRTUAL' required

Physical form factor of the card. Only VIRTUAL is supported in v1; PHYSICAL will be added in a later release.

last4string

Last four digits of the card PAN.

expMonthinteger

Card expiration month (1–12).

expYearinteger

Card expiration year (four digits).

fundingSourcestring required

Internal account id that funds this card.

maxSpendPerTransactioninteger nullable required

The largest amount this card can authorize on a single transaction, in the smallest unit of its currency (cents for USD). An authorization for exactly the limit is allowed. A later clearing can still settle above it — a restaurant tip, for example — so this caps the authorization, not the final settled amount. null means the card sets no limit of its own. If your platform config also sets cardConfigs.maxSpendPerTransaction (the platform-level limit), the lower of the two applies and this value stays as you set it.

maxSpendPerDayinteger nullable required

Card-specific cap on cumulative new spend during one UTC calendar day, in the smallest unit of the card's currency. The window resets at 00:00 UTC. Null means the card has no card-specific daily cap. When the platform config also supplies cardConfigs.maxSpendPerDay, Grid enforces the lower of the two values without replacing this configured value. Refunds, reversals, and authorization expiries do not restore capacity during the day. Spend exactly equal to the effective limit is allowed.

maxTransactionsPerDayinteger nullable required

Card-specific cap on the number of transactions the card may authorize during one UTC calendar day. The window resets at 00:00 UTC. Null means the card has no card-specific daily transaction cap. When the platform config also supplies cardConfigs.maxTransactionsPerDay, Grid enforces the lower of the two values without replacing this configured value. Each approved authorization counts once for the day it was authorized; refunds, reversals, and authorization expiries do not restore capacity during the day. A transaction that brings the day's count exactly to the effective limit is allowed.

currencystring

Currency the card transacts in, fixed at issuance by its card program. USDB-funded cards transact in USD, with funding converted at 1 USDB = 1 USD. Spending limits use the smallest unit of the card's currency (USD cents for USDB-funded cards). Changing the funding source does not change the card's currency or spending-limit units.

processorRefstring

Opaque processor-side reference for the card (e.g. the Lithic card token). Useful for cross-referencing in the processor's dashboards; not used for any Grid request routing.

issuerRefstring

Opaque identifier for the card on the issuer of record (e.g. the Lead Bank account/card identifier). Useful for cross-referencing in issuer dashboards; not used for any Grid request routing.

createdAtstring date-time required

Creation timestamp

updatedAtstring date-time required

Last update timestamp
