What is a card issuing API?

A card issuing API allows businesses to create and manage payment cards programmatically. MAGNETPAY's card issuing API lets you provision virtual cards instantly and order physical cards through a unified interface, regardless of the underlying provider. You control spending limits, merchant restrictions, and card lifecycle entirely through API calls.

Which card issuing providers does MAGNETPAY support?

MAGNETPAY integrates with Marqeta, WasabiCard (WSB), Wallester, NetPay247 Cards, PhotonPay Cards, and Fyatu Cards as card issuing providers. Each provider offers different BIN ranges, geographic coverage, and card features. Our abstraction layer lets you switch providers or use multiple simultaneously without changing your integration code.

How do funding pools work for card issuing?

Funding pools are pre-funded balances that back your issued cards. You deposit funds into a pool, and MAGNETPAY automatically distributes balances across providers as cards are loaded. This invisible load-spreading ensures high availability. When a cardholder spends, funds are debited from the pool in real-time.

Can I issue cards in multiple currencies?

Yes. MAGNETPAY supports card issuing in USD, EUR, GBP, and other major currencies depending on the provider and BIN program. Multi-currency cards can hold balances in several currencies simultaneously, with automatic FX conversion at the point of sale when the transaction currency differs from the card currency.

What compliance requirements apply to card issuing?

Card issuing requires KYC verification for cardholders and adherence to card network rules from Visa and Mastercard. MAGNETPAY handles BIN sponsorship and program management compliance. You are responsible for cardholder KYC — our built-in compliance module with Veriff integration can handle this automatically.
