Add Payment Card to Existing Customer Vault

The Add Payment Card endpoint allows you to attach a new payment card to an existing customer’s vault. This ensures customers have updated and valid payment methods stored for future transactions.

Key Features:

• Add New Cards: Easily associate additional payment cards with a customer.
• Secure Access: Requires the key-hash in the headers to authenticate the request and ensure data security.
• Default Card Option: If this is the first card added, it will automatically be set as the default payment method unless otherwise specified.

Usage Notes:

• Ensure you validate the card details before making the API request.
• Customers can have multiple cards, and the system will manage them as per your application logic for default or fallback payment methods.

Benefits:

Using this endpoint simplifies customer payment management by enabling you to keep payment details up to date and providing seamless options for recurring or new transactions.
