Moves money between the account and the card:
  • action: "LOAD" — fund the card from the account.
  • action: "UNLOAD" — move card funds back to the account.
The response includes the card’s availableBalance after the operation and a transactionId for tracking.
Only available on programs whose card provider keeps a separate card balance. On other programs the card spends directly from the account and this endpoint returns an unsupported-provider error.
