Create a prepaid card

Creates a new prepaid card for a specified wallet and program.

Authentication: x-api-key header required

Required Role: DEVELOPER, PRODUCTION

Important:

• For API key authentication: The wallet_id is determined by the API key itself (if the key is bound to a wallet)
• You cannot create cards for a wallet different from the one bound to your API key
• The vendor_id is automatically retrieved from the issuing_programs table based on program_id
• The program must have a configured vendor_id (not NULL or empty)
• The vendor_id will be passed to the external API automatically
