Header parameters missing from OpenAPI definitions

# Header Parameters Missing from OpenAPI Definitions Every day, API developers waste hours hunting through incomplete documentation, only to discover their header parameters—critical authentication tokens, language preferences, version specifications—are invisible to anyone consuming their API. The frustration cuts deeper when you realize your meticulously built endpoint works perfectly in production, but your OpenAPI spec is a lie: it tells developers there's nothing in the headers when there absolutely is. As one developer put it, "I have an endpoint parameter that I am parsing from language header. Problem is that it does not show up on OpenAPI/Swagger as a header parameter field"—a simple request that shouldn't require detective work. Teams resort to band-aid solutions like hand-written docs or Slack messages explaining what the schema forgot to mention, but these workarounds die the moment someone onboards, gets promoted, or leaves the company. The result is a cascade of integration failures, support tickets, and the slow corrosion of trust between API providers and the developers depending on them.
