Bulk Uploading PDFs to ArcGIS Online

[AmandaEggert]

I am uploading a LOT of pdf's to my ArcGIS Online Content for attachment to a shapefile that will eventually be uploaded as well.  However, I have not found a way to upload them all at once.  Is there a way to do so?  Going one-by-one is going to take weeks at this rate.

HI Amanda,

Are you trying to upload pdfs to your content or as attachments to features in a feature service?

I'm uploading to my content currently.  I'm going to link them in a shapefile, then upload the shapefile.
