}Cards
Trigger a card data refresh
Requests an updated balance for a card.
For U.S. non-reloadable cards (default), the card is re-scraped from the issuer via a retrieval queue and processed asynchronously. Rate limited per card to one request every 5 minutes, and to at most 12 refreshes in any rolling 24-hour period.
For international non-reloadable cards, a balance update request is recorded; an admin will manually update the balance within 24 hours. While a balance update is already pending for a card, additional requests for that card return 409.
Requires a Bearer token from /auth or /get-card.
