Forgot Password with asp.net identity

In my MVC and web API projects I'm using ASP.NET Identity for the Login.

This is my Forgot Password function on the AccountController:

[HttpPost]
[AllowAnonymous]
[Route("ForgotPassword")]
public async Task<IHttpActionResult> ForgotPassword(ForgotPasswordViewModel model) 
{
    if (ModelState.IsValid) 
    {
        var user = await UserManager.FindByNameAsync(model.Email);

        if (user == null || !(await UserManager.IsEmailConfirmedAsync(user.Id))) 
            return Ok();

        try 
        {
            var code = await UserManager.GeneratePasswordResetTokenAsync(user.Id);
            
            var callbackUrl = new Uri(@ "http://MyProject/ResetPassword?userid=" + user.Id + "&code=" + code);

            string subject = "Reset Password";
            string body = "Please reset your password by clicking <a href=\"" + callbackUrl + "\">here</a>";
            SendEmail(user.Email, callbackUrl, subject, body);
        } 
        catch (Exception ex) 
            throw new Exception(ex.ToString());

        return Ok();
    }

    // If we got this far, something failed, redisplay form
    return BadRequest(ModelState);
}

I'm getting the confirmation email, I am successfully redirected to the Reset Password View but then I'm not sure how to proceed.

How do I reset a password with the following parameters: NewPssword, ConfirmPassword and Code?

I tried to call the SetPassword method but got a 401 error.

self.resetPassword = function () {
    var data = {
        Email: self.loginUserName(),
        NewPassword: self.registerPassword(),
        ConfirmPassword: self.registerPassword2()
    }
    $.ajax({
        type: 'POST',
        url: '../API/Account/SetPassword',
        contentType: 'application/json; charset=utf-8',
        data: JSON.stringify(data),
        complete: showError
    });
}

And the setPassword function:

// POST api/Account/SetPassword
[Route("SetPassword")]
public async Task<IHttpActionResult> SetPassword(SetPasswordBindingModel model) 
{
    if (!ModelState.IsValid) 
        return BadRequest(ModelState);

    IdentityResult result = await UserManager.AddPasswordAsync(User.Identity.GetUserId(), model.NewPassword);

    if (!result.Succeeded) 
        return GetErrorResult(result);

    return Ok();
}

Currently the process is a s follow:

1. user clicks on "Forgot Password" link.
2. He is redirected to the Forgot Password View that has one field: Email.
3. The user provides his email address and submit the form.
4. the request is being sent to the Forgot Password function.
5. An email with a unique code is being sent to the client.

Till here I wrote the code and got it to work but I'm not sure how to implement the next steps:

6. The user is redirected the the Reset Password View that has 3 fields: Email, New Password and Confirm Password.
7. The user submits the form, a request is being sent to the SetPassword function (?) with the unique code and the user's password is being reset successfully.

Thanks in advance.

Sounds like your SetPassword api should call

var user = await UserManager.FindByNameAsync(model.Email);
if (user != null)
{
    var result = await UserManager.ResetPasswordAsync(user.Id, model.Code, model.NewPassword);
    if (result.Succeeded)
    {
          //handle success
    }
}
//handle invalid
