FAQs

Does Qolo offer an API for card issuing?

Yes. Qolo is an API-first platform. Card issuing, ledger management, virtual account configuration, and multi-rail payment orchestration are all accessible through API integration. Developers get one contract and one unified dashboard for the full payments stack. Qolo eliminates the need to integrate multiple payment vendors separately.

How quickly can we launch with Qolo?

Qolo is built to reduce time to value compared with legacy infrastructure and fragmented vendor models. Because the platform brings ledgering, cards, money movement, and controls together under simpleone APIs, customers can avoid the complexity of stitching together multiple providers before launch. Exact timelines depend on program scope, integration depth, and compliance requirements, but Qolo’s positioning is clear: launch modern payment capabilities faster without taking on a multi-year infrastructure project.

Does Qolo offer a sandbox and developer documentation?

Yes. Qolo offers a sandbox environment and developer documentation so teams can evaluate the platform and start building faster. The developer experience is built around a single API that supports virtual accounts, card issuing, money movement, programmable ledger logic, and risk controls. For technical buyers, that means less guesswork during evaluation and a clearer path from testing to production implementation.

Does Qolo support migration for existing programs?

Yes. Qolo supports program migration for customers moving off legacy processors or BaaS middleware providers. The migration process is structured to minimize disruption to existing cardholders and program operations. Qolo’s team works with customers to map existing program configurations, cardholder data, and balance structures to the Qolo platform before any cutover occurs. For platforms that have experienced BaaS failures or are proactively de-risking their infrastructure, Qolo has experience handling the technical and operational complexity of a live program transition.
