A Card Product is the template that defines everything about the cards you issue: the card scheme (Visa or Mastercard), enabled features, spend limits, and merchant category controls. Every card issued via the API is created from a product — the product ID determines what the card can and cannot do. Think of a product as your program blueprint. You configure it once, and every card issued under it inherits its rules.

​
Issuing Cards from a Product

Once a product is active, pass its productId when creating cards via the API: 
POST /api/v3.20/cards
{
  "cardholderId": "chl_...",
  "productId":    "prd_..."
}
The productId is shown on the product detail page in the portal and returned by the List Products endpoint.

​
Program Balance

All cards across all products draw from a single USD program balance pool. Fund it via USDT deposits — see Billing & Funding.
Cards cannot be issued or funded if the program balance is insufficient. Monitor the balance via the dashboard widget or subscribe to the ACCOUNT_LOW_BALANCE webhook event.
