For more detailed and up-to-date info - [Ignition 8.3 Early Access] Ignition 8.3 API Usage Guide (via Postman)

Collection and environment configs for the new 8.3 API routes can be imported in Postman for testing.

1. Import Collection config file in Postman.
2. Batch import environment configs.
3. On the 8.3 Collection parent level, navigate to Collection variables.
   • Set the desired target gateway address as necessary (default is http://localhost:8088).
     • Generate an API token on the test gateway and update the api_token variable
       • Note that the data/config/EXTERNAL/ignition/api-token directory location is preferred over data/config/CORE/ignition/api-token to better persist the token as the latter may be modified/cleared often by gwbk restores and/or manual intervention.
