Is there a way change the Controller's name in the swagger-ui page?
Solution 1
You can use tags for that. By default Swashbuckle adds a tag with the name of the controller to every operation. You can override that with the SwaggerOperationAttribute
. For instance, the next line replaces the default tag, Values, with the tag Test:
public class ValuesController : ApiController
{
[SwaggerOperation(Tags = new[] { "Test" })]
public IHttpActionResult Get()
{
// ...
}
}
The Get
operation will now be put in the group Test
.
If you want the operation to appear in multiple groups you can add more tags. For instance:
[SwaggerOperation(Tags = new[] { "Test", "Release1" })]
will put the Get
operation in the groups Test
and Release1
.
Solution 2
Version 5 of Swashbuckle supports the following option (to be used in the call to AddSwaggerGen()
):
options.TagActionsBy(api => new[] { api.GroupName });
This should be used in combination with the following attribute on your controllers or actions:
[ApiExplorerSettings(GroupName = "...")]
However, by default the group name is used to include the operation in a specific document. So this may lead to unexpected results (depends on your naming of the document in calls to options.SwaggerDoc(name, ...)
).
To make it work you may have to add this:
options.DocInclusionPredicate((name, api) => true);
Here, for every operation, name is the name of a document and the group name is available in api.GroupName
. To include the operation in the document regardless of its group name, simply return true.

I tried using venerik's answer, but it still kept the original controller name in the UI along with the new tag that you specify. I also didn't like that you had to add an attribute to every function, so I came up with a solution where you only have to add an attribute to the controller. There are two steps:
Add DisplayNameAttribute
on the controller:
[DisplayName("Your New Tag")]
public class YourController : ApiController
{
// ...
}
Then in the Swagger configuration, you can override the base functionality using the GroupActionsBy
function to pull the name that you specified in that attribute:
GlobalConfiguration.Configuration
.EnableSwagger(c => {
c.GroupActionsBy(apiDesc => {
var attr = apiDesc
.GetControllerAndActionAttributes<DisplayNameAttribute>()
.FirstOrDefault();
// use controller name if the attribute isn't specified
return attr?.DisplayName ?? apiDesc.ControllerName();
});
})
.EnableSwaggerUi(c => {
// your UI config here
});
ControllerName()
is an extension method defined in the Swagger-Net library. If you aren't using that you can also get the controller name from apiDesc.ActionDescriptor.ControllerDescriptor.ControllerName

By default if I have a controller called ShippingController then the swagger generated UI with name "Shipping"
I was looking to change the name of my controller to something more friendly or in another language. The best I could find was to use a SwaggerOperation attribute to change the name, but this has the limitation that it is a method level attribute and I dont really want to specify the name on every method.
So, I created a convention class to use with controller Route attribute, that we usually use on our controllers and then have the swagger use that to be the name of the controller. Well you know there is a name property on the attribute but the generated swagger doesnt seem to use it.
STEP 1: Create this class:
When the app starts up it will run this and I will be able to look up the Route attribute on my controllers if they have the attribute specified and then use the name property to change the name of the Controller.
using Microsoft.AspNetCore.Mvc;
using Microsoft.AspNetCore.Mvc.ApplicationModels;
namespace RestServices.Configuration.ConfigInstallers.Conventions
{
public class ControllerDocumentationConvention : IControllerModelConvention
{
void IControllerModelConvention.Apply(ControllerModel controller)
{
if (controller == null)
return;
foreach (var attribute in controller.Attributes)
{
if (attribute.GetType() == typeof(RouteAttribute))
{
var routeAttribute = (RouteAttribute)attribute;
if (!string.IsNullOrWhiteSpace(routeAttribute.Name))
controller.ControllerName = routeAttribute.Name;
}
}
}
}
}
STEP 2: Startup.cs:
Modify the StartUp.cs file and in the configure services we need to register our class in the Conventions list. See below:
services.AddControllers(o =>
{
o.Conventions.Add(new ControllerDocumentationConvention());
});
STEP 3: In each controller add name property in Route Attribute:
[ApiController]
[ApiVersion("1.0")]
[ApiExplorerSettings(IgnoreApi = false, GroupName = "v1")]
[Route("api/Envios/{version:apiVersion}", Name = "Envios", Order = 1)]
[Produces("application/json")]
public class ShippingController
Now when I run the app and my swagger is generated you can see the controller name is changed to be the same as the text in the route attributes name property.
Solution 5
Starting with ASP.NET Core 6, you can use the TagsAttribute
either on Controller level:
[Tags("entity")]
[ApiController]
public class DerivedEntitiesController : ControllerBase
{
or on Action level:
[Tags("entity")]
[HttpPut("entity/{key}")]
public IActionResult PutEntity(Guid key, [FromBody] Entity entity)
{
Swagger will group according to the Tags
and respect API Versioning.

XN16 over 1 year
I'm using Swashbuckle to enable the use of swagger and swagger-ui in my WebApi project.
In the following image you can see two of my controllers shown in the swagger-ui page. These are named as they are in the C# code, however I was wondering if there was a way to change what is shown here?
This is mainly because as you can see
ManagementDashboardWidget
is not a user friendly name, so I want to change it to be user friendly.-
Sampada over 7 yearsHave you tried using swagger's @Api as an annotation for your restful service class?
-
XN16 over 7 years@Sampada I am unsure how to access that, could you give me a bit more information please?
-
Sampada over 7 yearsI am sorry @API is available for swagger in Java, not in swashbuckle swagger.

Sn3akyP3t3 over 2 yearsYou may be able to achieve your goal simply by naming the .cs file to match your intentions. For example name your controller code file to GroupNameGoesHereController.cs and in swagger you will see the group named GroupNameGoesHere. Unfortunately, that doesn't support spaces in the name so if you want that your better off going with alternative options.

Larry over 2 yearsRenaming the .cs cannot be applied in my case. For example, I have different controller classes for a same route, because of the DI instanciation which differs a lot.

XN16 over 7 yearsThat's exactly what I wanted... I just never found much documentation on that part. Thanks very much.

jtate over 4 yearsThis works, but it still leaves the controller name as a tag in the UI, but with no actions under it. For example, say I have
ABCController
but I've added[SwaggerOperation(Tags = new[] { "DEF" })]
to all routes, the UI shows "ABC" and "DEF", but there is nothing under "ABC". How do we get rid of "ABC" altogether? -

apiDesc.ControllerName
isn't a method. Maybe I'm using a different version ofSystem.Web.Http

jtate over 4 years@CodyStott
ControllerName()
is an extension method defined in the Swagger-Net library, which is another library very similar to Swashbuckle (which is what I assume you are using). Having said that, you should able to useapiDesc.ActionDescriptor.ControllerDescriptor.ControllerName
to get the controller name. -
Elmar almost 3 yearsThat is very elegant. Great suggestion!
-
Diego B almost 3 yearsTake a look to my answer below. I hope it helps you!
-
oatsoda almost 3 yearsShould probably point out that by setting the
DocInclusionPredicate
totrue
then should you need to include Multiple Documents in the future, then you'd need to find another way. -
Declan McNulty almost 3 yearsWorked a treat!

guppy81 almost 2 yearsGood solution, also usable with NSwag, where
options.TagActionsBy
not available. Little improvement to not missusename
-property from Route-attribute, which seems not being the best matching attribute for me to use for that: I'm using theApiExplorerSettingsAttribute
to set the group name instead and using this attribute in theControllerDocumentationConvention
.
