How to get api-key security schema working

[ahoehma]

May a stupid question but I can't find a docu or howto or something.

I have already this:

@Configuration
class OpenApiConfiguration {

  @Bean
  OpenAPI customOpenAPI(final CadWebServiceProperties properties) {
    return new OpenAPI()
        .components(
            new Components()
                .addSecuritySchemes("apiKey",
                    new SecurityScheme().type(APIKEY).in(In.HEADER).name(properties.authTokenHeaderName())));
  }

}

I can use the schema in swagger ui:

But then when I send requests ... the header is not in requests. I checked with chrome network console.

Where is the missing magic?

Kind regards
