Unregister a credit card

This Tango endpoint allows you to remove a previously registered credit card from your Tango account, ensuring it can no longer be used to fund transactions. This is typically done when a card expires, is replaced, or should no longer have access for funding. Once unregistered, the card cannot be used again unless it is re‑registered. See how you can Register a new credit card with Tango API.

In some rare instances, Tango may choose to unregister credit cards at its own discretion. If this occurs Tango will make a best effort to notify the business contact on the account.
