“Our developers really like the platform, and the reason for that is that the documentation is really well-written. The APIs are very well designed, so it’s easy to understand. It’s built on cutting-edge technology, like SOAP messages, JSON, REST, and this is something that a top modern company like Klarna expects from our partners.”

Use a private sandbox to test and simulate transactions
Sign up and kick off your private sandbox in just three clicks. Create your card product, accounts, and cardholders, and start simulating transactions. Leverage developer guides and tutorials to get started fast. Leverage software development kits (SDK)s to integrate with your application.
Design a highly configurable payment solution
Use open APIs to customize your card experience, authorization controls, spend limits, accepted merchants and countries, time and frequency of use, and more. Take advantage of program constructs already approved by Visa and Mastercard to rapidly launch your program and deliver cards to cardholders in no time.
Gain full visibility into your card activities
Implement webhooks to send real-time notifications to an endpoint hosted on your environment. Receive and process events relating to cards, users, digital wallets, transactions, cases, and chargebacks. Marqeta uses Hash-based Message Authentication Code (HMAC) to secure the exchange.
