Hi LukeHagar ,
You can add headers in two ways:
- As a parameter (in: header)
- As a security requirement
If you're looking to have these headers across the entire API, all operations you _might_ want to use security, where you can use the root-level `security: ...` field. See https://swagger.io/docs/specification/authentication/.
For bulk-adding parameters. This is a challenge to other folks too, a proposal was started to help with it called "Overlays" which is a separate document to do bulk modifications to an OpenAPI file, see: https://github.com/OAI/Overlay-Specification. The spec would allow you to say things like: "Add this parameter to every operation".
Related is the idea of "traits" which is a grouping of $refs. This isn't supported by OpenAPI (today) it might be in a later version of the spec.
