Easy to use

Our REST API uses JSON based resource-oriented URLs. It’s predictable and comes with Swagger based API documentation for ease of integration. As well as a full sandbox environment for testing.



All our services are built API-first, so there’s nothing you can’t access. Start using accounts within seconds. Use rules to automate complex flows. Receive webhook payment notifications.



Our API was purpose-built from ground up. It’s secured with TLS 1.2 and SHA-1 HMAC. And regularly enhanced with new payment features, while remaining backwardly compatible.

What our API integrated customers say

"Modulr’s API is a scalable, automated way of paying people, which allows us to be cost efficient, otherwise we’d need a much larger finance team. We didn’t want to employ a team of three to five people to do this."

"Quite simply, Modulr offered a great solution for our business needs. Where we were faced with complexity, which would have slowed development, Modulr has brought us simplicity, clarity, speed to market and great service"
