How can view the swagger ui for Azure API app

In the configuration of your WebAPI project (SwaggerConfig.cs in the folder App_Start), you have to enable the Swagger UI. It is commented out as default behavior.

Just open the configuration, search for:

                /*                    })                .EnableSwaggerUi(c =>                    {                */

and disable the comments in the lines above and under it

Pedro, above, has provided a perfect answer for enabling SwaggerUi.As for your question regarding the URL "swagger/docs/v1"

This is the default URL used by Swashbuckle to return Swagger 2.0 JSON metadata for the API

The SwaggerConfig.cs file is created when you install the Swashbuckle package in a project. You can find it in the folder "App_Start" . It provides a number of ways to configure Swashbuckle. I haven't checked if you can change that default URL or do URL rerouting for it.

Edited:

The default route templates for the Swagger docs and swagger-ui are "swagger/docs/{apiVersion}" and "swagger/ui/{*assetPath}" respectively. You can change these so long as the provided templates include the relevant route parameters - {apiVersion} and {*assetPath}.For example: the URL to swagger-ui will be myswag/index.

httpConfiguration .EnableSwagger("docs/{apiVersion}/swagger", c => c.SingleApiVersion("v1", "A title for your API"))

.EnableSwaggerUi("myswag/{*assetPath}");

You can read more about it here in the GitHub repo: https://github.com/domaindrivendev/Swashbuckle

If you are creating API using Template Azure API App in visual studio, you just need to un-comment few lines from SwaggerConfig.cs file to activate Swagger for your API application.

1. In your solution look for the file 'SwaggerConfig.cs'

   'VSSolution' > App_Start > SwaggerConfig.cs

2. Look for EnableSwaggerUi and remove comments for below line of code

               /*                })            .EnableSwaggerUi(c =>                {            */

3. That's it, No Other Configuration Required.

   Just run the application :http://localhost:57452/swagger
