You can download a machine-readable interface documentation file in the OpenAPI V3 format directly from the page.

After downloading the file, you can generate code that interfaces directly with our system, according to the programming language you use. For example, you can search the web for “OpenAPI client generator PHP” or “OpenAPI client generator .NET.” You will find several tools that can be used to generate client-side integration code.
For example, to prepare a client in C#, you can use:
NSwagStudio · RicoSuter/NSwag Wiki · GitHub

You can import the file into Postman to perform tests. Select API and import the machine-readable documentation file.
