Postman WebApi Help Documentation

Nuget Package

Postman MVC WebApi Help Documentation

Allows developers expose their WebAPI endpoints so they can be imported into postman as a collection. It generates json that conforms to the Postman Collection Format v1.0.0.

Source

It is based on the original answer to a question on Stack Overflow How to generate JSON Postman Collections from a WebApi2 project using WebApi HelpPages that are suitable for import by Robert H. Engelhardt (rheone) and is released under a Creative Commons Attribution-ShareAlike 3.0 Unported licence.

##Getting Started

1. Install the Nuget package

   Install-Package Postman.WebApi.HelpDocumentation

2. Import Api into Postman

   Collections -> Import -> Import from a Url -> Success!

Customization

Sometime one prefers to use a "human friendly" name for the requests. To do so simply edit the PostManController constructor.

public PostmanApiController()
{
  _requestNamingStyle = RequestNamingStyle.Url;
}

There are two options: Url and ActionName (split on Uppercase and drops "Async" keyword.)

Improve Documentation

Enable Xml Comments

1. Project Properties -> Build -> Tick "XML documentation file"
2. Change location to App_Data/XmlDocument.xml
3. Project\Areas\HelpPage\App_Start\HelpPageConfig.cs
   pascalCopy

   config.SetDocumentationProvider(new XmlDocumentationProvider(HttpContext.Current.Server.MapPath("~/App_Data/XmlDocument.xml")));

4. Provide xml comments on controller and actions

Provide Actual Types

If using HttpRequestMessage or HttpResponseMessage the documentation won't provide meaningful examples in either the Help Page or the Postman Help

To cater for this abstration you can configure the WebApi Help with the actual types

Requests

Project\Areas\HelpPage\App_Start\HelpPageConfig.cs

config.SetActualRequestType(typeof(MyType), "MyController", "MyAction");

Responses

Project\Areas\HelpPage\App_Start\HelpPageConfig.cs

config.SetActualResponseType(typeof(MyType), "MyController", "MyAction");

or

Use the ResponseType attribute on the action

[ResponseType(typeof(MyType))]
public HttpResponseMessage Post(HttpRequestMessage request)
{
}

Sample Data

Sometimes the default values for types are not good enough so it is useful to post meaningful sample data.

Project\Areas\HelpPage\App_Start\HelpPageConfig.cs

config.SetSampleObjects(new Dictionary<Type, object>
{
  {
    typeof(Person), new Person
    {
       Id =  1,
       Firstname =  "Abbott",
       Surname =  "Robertson",
    }
  }
});
