What is Contro CaaS?

Contro’s Card-as-a-Service (CaaS) platform lets partners issue and manage branded payment cards through a single API. You handle the user experience — we handle card issuance, compliance, and processing.

​
Key concepts

Partners

Your organization. Each partner gets API keys, a prefunded balance, and access to card programs.

Cardholders

End users who receive cards. You create cardholders, submit them for KYC, and manage their lifecycle.

Card Programs

Card configurations (brand, currency, region) available to your account. Browse programs and issue cards from them.

Cards

Virtual or physical cards issued to cardholders. Cards can be activated, frozen, unfrozen, or cancelled.
