Explore Finxact’s Open Core API

Finxact is the first core banking provider to join the Open API Initiative and build upon The OpenAPI Specification, formerly known as the Swagger Specification.

We welcome Banks and Partners who want to create, scale, modernize, and monetize their existing and new banking solutions with open access to the most modern, and transparent core banking service available.
