Append Data to Feature Service - ArcREST-3.0.1

[ErnestoCarreras3]

I am trying to use the script tool available with the ArcREST-3.0.1 package but not sure why is not working as I expected (the package has been successfully installed already). As far as I understood, it should append new data to an existing feature service. I have already a service published in my organization account. The data that I want to append has the same database structure along with some attachments. After providing username/password, organization URL, FS Item ID, layer name and source table (the new data I want to include to the existing FS), the tools seems to execute without any issues. Once I check the service, the data is not there. Anything I am missing here?

Thanks in advanced.

I believe the hosted feature layer needs to be editable...you can do that via the item details page in AGOL.  I also believe there is an toggle edit button if you are running the ArcREST script as a tool.
