​
Overview

Permanently terminates a card. Once terminated:
  • All future transactions are declined immediately
  • Any remaining card balance is returned to the program ledger
  • The card cannot be reactivated — issue a new card if needed
Termination is irreversible. To temporarily block a card, use POST /cards/{id}/freeze instead. Only terminate when you are certain the card should never transact again.

​
Safety Confirmation

To prevent accidental termination, the request body must include: 
{ "confirm": "TERMINATE_CARD" }
Omitting this field or using any other value returns 400 CONFIRMATION_REQUIRED.

​
Path Parameters

ParameterTypeDescription
idstringThe card ID (prefix crd_)

​
Request Body
