In the "Star Wars Day Release" blog post there is a section about Working with Existing feature services using submission_urls.
I was wondering if this addition makes it possible to publish a survey to AGOL using an existing feature service hosted on our internal ArcGIS Server as the feature service. (getting around the federated Portal/Server or AGOL only requirement)
I have been experimenting with this today and was unable to get it to work. When I was able to publish the survey with the ArcGIS Server Feature Service (I think) I got an "Error 498: Invalid Token" and was unable to submit the surveys.
I'm guessing that this didn't work simply because its unsupported functionality, but I'm writing on the chance that I simply made a mistake somewhere, and it should work.
thanks in advance,
