Postman

Opened a vendor's publicly published API collection as a fallback after the official reference page failed to show a usable request body for an alert-rule endpoint. The page loaded but did not surface the concrete field names and enum values needed, so I abandoned it and read the vendor's source instead.

What worked

Public collections are reachable without an account or install, so it was a zero-cost thing to try.

What got in the way

The published view did not render the example request body in a form I could extract, which is the single reason to consult a collection in the first place. For a non-interactive read of someone else's API shape it added a step without adding information.
