Steps
Create an API User in Ungerboeck's API User window and note its credentials, used to sign the JWT
Import the PostmanJwt collection from github.com/UngerboeckAPI/PostmanJwt to see a working JWT-generation request, setting the API User's variables in your Postman environment
Alternatively use the JavascriptJwtExample repo for a basic JWT-generating JS call against the GET Account endpoint, or CORSJavascriptExample if calling the API from a browser
Clone the versioned example repo matching your Ungerboeck release (e.g. UngerboeckAPI/262 for release 26.2) for a C# solution that generates the JWT and calls the API end-to-end
Use the generated JWT as your bearer credential on subsequent Open API requests
Known gotchas
Example/SDK repos are versioned per Ungerboeck release (243, 244, 251...262); using an example built for a different release than your instance can hit removed or changed endpoints
Browser-based calls need CORS explicitly enabled per the CORSJavascriptExample instructions — a plain fetch/XHR from a webpage is blocked otherwise
JWTs are generated from API User credentials, not your personal login — treat the API User's credentials as the real secret, not just the resulting JWT
