FISPAY API

Placeholder

This site shows the documentation pipeline. The message catalog is a placeholder until the real one lands.

The FISPAY API is how a sale system, such as a cash register, talks to a FISPAY payment terminal. Both sides exchange JSON messages; each message names its operation in a common header.

The specification lives in Git. This website, the PDF and the tests are all built from the same commit, so they always agree. The footer shows the specification version and that commit.
