If you want to return a response which needs to be constructed through a complex logic, say lots of response headers, etc, you can abstract all those logic into an action result class implementing IHttpActionResult and use it in multiple action methods to return response.
What is the difference between ActionResult and IHttpActionResult?
IHttpActionResult is for ASP.NET Web Api, while IActionResult is for ASP.NET Core. There’s no such thing as “Web Api” in ASP.NET Core. It’s all just “Core”. However, some people still refer to creating an ASP.NET Core API as a “Web Api”, which adds to the confusion.
How do I convert IHttpActionResult to HttpResponseMessage?
A New Way to Send Response Using IHttpActionResult

What is HttpResponseMessage?
A HttpResponseMessage allows us to work with the HTTP protocol (for example, with the headers property) and unifies our return type. In simple words an HttpResponseMessage is a way of returning a message/data from your action.
What is IHttpActionResult?
IHttpActionResult contains a single method, ExecuteAsync, which asynchronously creates an HttpResponseMessage instance. If a controller action returns an IHttpActionResult, Web API calls the ExecuteAsync method to create an HttpResponseMessage. Then it converts the HttpResponseMessage into an HTTP response message.
Is IHttpActionResult asynchronous?
Your action may return an IHttpActionResult which performs the action asynchronously when the framework calls its ExecuteAsync . But if you must first make some other async calls before creating and returning the result, then you’re forced to change the signature to async Task . That’s all it is.
How do I respond to IHttpActionResult?
Convert directly to an HTTP response message. Call ExecuteAsync to create an HttpResponseMessage, then convert to an HTTP response message. Other type Write the serialized return value into the response body; return 200 (OK). The IHttpActionResult interface was introduced in Web API 2.
What does IHttpActionResult return?
IHttpActionResult ultimately returns HttpResponseMessage by providing the customization and reusability features to the developer. IHttpActionResult contains ExecuteAsync method to create an instance of HttpResponseMessage asynchronously.
What is IHttpActionResult in Web API?
The IHttpActionResult interface was introduced in Web API 2. Essentially, it defines an HttpResponseMessage factory. Here are some advantages of using the IHttpActionResult interface: Simplifies unit testing your controllers. Moves common logic for creating HTTP responses into separate classes.
What namespace is IHttpActionResult in?
System.Web.Http namespace
The IHttpActionResult interface is contained in the System. Web. Http namespace and creates an instance of HttpResponseMessage asynchronously. The IHttpActionResult comprises a collection of custom in-built responses that include: Ok, BadRequest, Exception, Conflict, Redirect, NotFound, and Unauthorized.

What is ihttpactionresult in web API?

What are the advantages of using ihttpactionresult in Salesforce?
By using the IHttpActionResult we are only concentrating on the data to be send not on the status code. So here the code will be cleaner and very easy to maintain. Unit testing of the implemented controller method will be easier. Uses async and await by default.
How do I return an ihttpactionresult asynchronously?
Your action may return an IHttpActionResult which performs the action asynchronously when the framework calls its ExecuteAsync. But if you must first make some other async calls before creating and returning the result, then you’re forced to change the signature to async Task .
