Answer 1

tried submitting as an edit to @ManOVision's answer, but it might be more appropriate to show separately.

In implementing his answer, i found that it does not support binding params that are optional. i've made some updates to support that as shown below.

the error i was receiving when not passing the param was:

{
    "Message": "The request is invalid.",
    "MessageDetail": "The parameters dictionary does not contain an entry for parameter 'skus' of type 'System.String[]' for method 'System.Web.Http.IHttpActionResult Get(System.String[], System.String, System.String, System.String, System.String, Boolean)' in 'eGAPI.Controllers.GiftCardsController'. The dictionary must contain an entry for each parameter, including parameters that have null values."
}

implementation:

[Route("{skus}")]
public IHttpActionResult Get([FromUriCsv] string[] skus = null)

updated code:

public override Task ExecuteBindingAsync(ModelMetadataProvider metadataProvider, HttpActionContext actionContext, CancellationToken cancellationToken)
{
    var paramName = Descriptor.ParameterName;

    try
    {
        if (actionContext.ControllerContext.RouteData.Values.ContainsKey(paramName))
        {
            var rawParamemterValue = actionContext.ControllerContext.RouteData.Values[paramName]?.ToString();

            if (!string.IsNullOrEmpty(rawParamemterValue))
            {
                var rawValues = rawParamemterValue.Split(new[] { ',' }, StringSplitOptions.RemoveEmptyEntries);

                actionContext.ActionArguments[paramName] = JsonConvert.DeserializeObject($"[\"{string.Join("\",\"", rawValues)}\"]", Descriptor.ParameterType);
            }
            else
            {
                actionContext.ActionArguments[paramName] = null;
            }
        }
        else
        {
            actionContext.ActionArguments[paramName] = null;
        }
    }
    catch (Exception)
    {
        actionContext.ActionArguments[paramName] = null;
    }

    return Task.FromResult
