I searched many threads, but the only solution I found is to add params to all operations.

In my API, I expect a custom header to be always present. It should be passed in all operations. In the spec it is set like this:

...
"parameters": {
      "salesUnitHeader": {
        "name": "SALES-UNIT",
        "in": "header",
        "description": "Sales Unit Header",
        "required": true,
        "schema": {
          "type": "string"
        }
      }

Actually what I want is that the SwaggerUI user sets the sales unit once and then all endpoints use this parameter. However, the only two options I see are, set it per endpoint, but then the user has to set the header again and again or put the header in the authorization which I actually don’t want.

Isn’t there an option to display form input fields in the header for header params and SwaggerUI will use the data for all endpoints?
