API Key Header not sent from SwaggerUI to API

[Montago]

I've added the SecurityDefinition as well as SecurityRequirements as described here : https://stackoverflow.com/questions/57227912/swaggerui-not-adding-apikey-to-header-with-swashbuckle-5-x

services.AddSwaggerGen(c =>
			{
				c.AddSecurityDefinition("Api Key in Header", new OpenApiSecurityScheme()
				{
					Name = "x-api-key",
					In = ParameterLocation.Header,
					Type = SecuritySchemeType.ApiKey,
					Description = "Authorization by x-api-key inside request's header",
				});

				var key = new OpenApiSecurityScheme()
				{
					Reference = new OpenApiReference
					{
						Type = ReferenceType.SecurityScheme,
						Id = "x-api-key"
					},
					In = ParameterLocation.Header,
					Type = SecuritySchemeType.ApiKey
				};
				
				var requirement = new OpenApiSecurityRequirement
				{
				   { key, new List<string>() }
				};

				c.AddSecurityRequirement(requirement);
			});

which result in the Authorize option pops up in UI:

However The API Key isn't sent from SwaggerUI to the Endpoint:

The header is missing

This is also the case if i inspect the Request.Headers object in the backend.

Am i missing something ?

Hi @Montago

here is working configuration ( I tested it using it DotSwashbuckle but it should work in Swashbuckle too ):

  c.AddSecurityDefinition("ApiKeyHeader", new OpenApiSecurityScheme()
  {
      Name = "x-api-key",
      In = ParameterLocation.Header,
      Type = SecuritySchemeType.ApiKey,
      Description = "Authorization by x-api-key inside request's header",
  });
  c.AddSecurityRequirement(new OpenApiSecurityRequirement{
      {
          new OpenApiSecurityScheme
          {
              Reference = new OpenApiReference { Type = ReferenceType.SecurityScheme, Id = "ApiKeyHeader" }
          },
          new string[] {}
      }
  });

The security definition needs to be associated with the security requirement
