I have created (yet another) Postman collection for the IDN API. Now that PATs are available for authentication, the process is much more straightforward then it was before. No more "full authentication required" or wrangling of URLs and cookies. The one time setup consists solely of creating a PAT in the IDN UI and adding it to Postman. That's it.
With the first API call, the PAT is used to generate an access token which is then used for subsequent API calls. The access token will eventually expire but Postman monitors that condition and will generate a new token as needed.
Feel free to give it a try and let me know of any comments.
