Get card details
Returns the current status and details of card orders. If card_id is provided, returns a single card, looked up across U.S. non-reloadable, international non-reloadable, and reloadable cards. If omitted, returns all cards of the given card_type for the authenticated user; card_type defaults to Non-Reloadable U.S. when omitted, so existing callers see unchanged behavior. Pass card_type=Non-Reloadable International to list international cards, or card_type=Reloadable to list reloadable cards.
For U.S. non-reloadable cards, details take ~7-10 seconds to become available after ordering; poll every 2-3 seconds until status is "ready", then read card_details. For international non-reloadable cards, the order is queued until an admin fulfills it (typically within 24 hours), after which card_details is populated.
For international cards, the card_id returned by /order-intl-card is a queue id. After admin fulfillment, the issuer's transaction id becomes the new card_id and the original queue id is preserved on the card as queued_order_card_id. You can keep polling /get-card-data?card_id=<original-queue-id> and it will resolve to the fulfilled card.
Reloadable cards are a separate product, set up by the account holder in the Laso dashboard rather than ordered through this API. They are reusable (a multi_use card stays open across charges until its limit is spent) and can be topped up, unlike the single-load non-reloadable cards. Listing them returns balance, spend_limit, last4, expiry, and reusable. If the wallet has no card issuer account linked, the list is empty and a note explains how the holder sets one up.
Reading a reloadable card's number and CVV is gated by the card issuer, and which gate applies depends on who issued it. Request the card by card_id; the response carries exactly one of three fields. card_details is the normal result for a card created through /create-reloadable-card, which Laso issues on the holder's behalf and can read for them directly — no approval step is involved. details_approval with status: "pending" and an approval_id appears only for a card the holder created in a DIFFERENT app: the issuer has emailed them an approve/deny link, and once they approve you retry as GET /get-card-data?card_id=<CARD_ID>&approval_id=<APPROVAL_ID> to receive card_details. details_error means the issuer could not return the number; retry shortly, and if it persists the holder can read the card in the dashboard. Spend the card by entering its number, expiry, and CVV at the merchant's checkout. billing_address is null on these cards and always will be — the issuer holds no billing address for a card. If a merchant requires one, use the address the account holder gave at identity verification (ask them; do not guess), since these cards are AVS-checked against it and a mismatch is the most common decline on a card that has funds. A card with reusable: true stays open after an approved charge and can be spent again up to its remaining balance; a charge larger than the balance is declined in full, as there are no partial approvals.
Requires a Bearer token from /auth or /get-card.

Query parameters
The card ID returned from /get-card or /order-intl-card, or a reloadable card's id from card_type=Reloadable. Looked up across all three card types. If omitted, returns all cards of card_type.
When listing all cards (no card_id), filters by card type. Defaults to Non-Reloadable U.S. if omitted (preserves existing client behavior). Pass Non-Reloadable International to list international cards, or Reloadable to list reloadable cards.
Reloadable cards only, and only for a card the account holder created in a DIFFERENT app: pass the approval_id from a prior details_approval response once they have approved it. Cards created through /create-reloadable-card are Laso-issued and never require this.
Response
Card status and details. Returns a single CardData object when card_id is provided, or { "cards": CardData[] } when omitted.
