OpenAPI 3 Custom type in Authorization header

Question

I am looking for the proper way to specify an Authorization header with a custom type like ApiKey in openAPI 3.

The custom Authorization header should look like

Answer 1

I think I have found a way that seems acceptable - although not perfect. Would like to see something better in the future...

It seems that there is no other way than to add the custom type to the value (aided by a description like below).

components:
  securitySchemes:
      ApiKey:
         type: apiKey
         name: Authorization
         in: header
         description: 'Prefix the value with \"ApiKey\" to indicate the custom authorization type' 
security:
   - ApiKey: []

This does at least produce the correct header in curl (if applied correctly).
