Use this API to enable or disable specific features on an existing card. Pass the cardId as a path parameter to identify the card, then specify which features to toggle in the request body.

The following card features can be controlled individually:

• Online Payments — allow or block card usage for internet-based transactions
• POS Payments — enable or disable in-store point-of-sale payments
• Contactless Payments — turn tap-to-pay functionality on or off
• ATM Withdrawals — permit or restrict cash withdrawals at ATMs
• International Payments — allow or block transactions made outside the home country

Note: The card must be activated before its features can be toggled. Attempting to update an inactive card will result in a 403 error.

A successful response confirms that the specified card features have been updated.
