Javascript API: Adding a shapefile with more than 1000 points

[CoreySchafer]

I am able to add shapefiles with less than 1000 points by using the ArcGIS Portal REST API as shown in this example:
Add shapefile | ArcGIS API for JavaScript

However, there is a 1000 point maxRecordCount through their service. I have tried setting the maxRecordCount in the publishParameters without any luck. I also thought it may be possible to publish our own service with a raised maxRecordCount, but I am not very experienced in publishing custom scripts and did not know whether there was a toolbox that already provided this functionality.

So my question is, is there a way to use the ArcGIS Portal REST API to return more than 1000 records? If not, what would be the best approach to solve this problem?

Thank you!

you should be able to edit the service to update the service maxrecordcount. But I've never had a problem publisihing it with the desired number; Typically I set it at 5000.
