Is it possible to connect to Finmatics via REST API?

Yes, Finmatics provides a REST API.

APIs, or application program interfaces, allow the functions of one computer program to be used by another. They are a means by which two different programs can communicate. REST APIs can be used by IT for software integration and automation purposes.

The Finmatics API documentation can be found here (user: demo | PW: demodemo).

To request an API user, please contact your Finmatics sales representative.
