Meet Marqeta

Marqeta is a card issuing and payment processing platform for businesses building financial products. Its APIs let teams create physical, virtual, and tokenized cards, manage cardholders, and decide how transactions are authorized. Developers can set rules for spending amounts, merchants, and timing, then receive transaction updates through webhooks.

The platform supports debit, prepaid, and credit programs, with tools for card management, funding, clearing, and reconciliation. Just-in-Time Funding lets prepaid programs fund purchases at authorization instead of setting aside money in advance. Teams can test integrations and simulate transactions in a private sandbox before launch. Common uses include corporate expense cards, supplier payments, and digital banking experiences embedded in an existing app or service.
