# 16.0: Http Methods

## Add `IHttpActionResult` for all CRUD Endpoints

1. Open **ElevenNote.WebAPI -> Controllers -> NoteController**
2. Rename the `Get()` method to `GetAll()` to distinguish getting all the notes from getting just one note.
3. See below for stubbing out the other `IHttpActionResults` for `Get`, `Post`, `Put`, and `Delete`
4. `CTRL .` To bring in the using statement for the models. If you are using your own application, be sure to use the appropriate models from the .Models project, not the .Data assembly.

```csharp
    namespace ElevenNote.WebAPI.Controllers
    {
        [Authorize]
        public class NoteController : ApiController
        {
            public IHttpActionResult GetAll()
            {
                NoteService noteService = CreateNoteService();
                var notes = noteService.GetNotes();
                return Ok(notes);
            }

            public IHttpActionResult Get(int id)
            {
                return Ok();
            }

            public IHttpActionResult Post(NoteCreate note)
            {
                return Ok();
            }

            public IHttpActionResult Put(NoteEdit note)
            {
                return Ok();
            }

            public IHttpActionResult Delete(int id)
            {
                return Ok();
            }

            private NoteService CreateNoteService()
            {
                var userId = Guid.Parse(User.Identity.GetUserId());
                var noteService = new NoteService(userId);
                return noteService;
            }
        }
    }
```

## Get Method

Finish out the `Get(int id)` method:

```csharp
public IHttpActionResult Get(int id)
{
    NoteService noteService = CreateNoteService();
    var note = noteService.GetNoteById(id);
    return Ok(note);
}
```

## Post Method

Finish out the `Post(NoteCreate note)` method:

```csharp
public IHttpActionResult Post(NoteCreate note)
{
    if (!ModelState.IsValid)
        return BadRequest(ModelState);

    var service = CreateNoteService();

    if (!service.CreateNote(note))
        return InternalServerError();

    return Ok();
}
```

## Put Method

Finish out the `Put(NoteEdit note)` Method:

```csharp
public IHttpActionResult Put(NoteEdit note)
{
    if (!ModelState.IsValid)
        return BadRequest(ModelState);

    var service = CreateNoteService();

    if (!service.UpdateNote(note))
        return InternalServerError();

    return Ok();
}
```

## Delete Method

Finish out the `Delete(int id)` method:

```csharp
public IHttpActionResult Delete(int id)
{
    var service = CreateNoteService();

    if (!service.DeleteNote(id))
        return InternalServerError();

    return Ok();
}
```

# Agent Instructions: Querying This Documentation

If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter:

```
GET https://eleven-fifty-academy.gitbook.io/dotnet-201-elevennote/elevennote-api-parts-13-19/part-16-http-methods/16.0-httpmethods.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
