Is it possible to toggle on/off the "Export Data - Allow others to export to different formats" option for a hosted feature layer from the ArcGIS API for Python?
Hi David,
Yes, you can do this with the following:

The service previously only had 'Query' capabilities. The above code will now enable 'Extract' which will allow others to export the data.
@JakeSkinner - Yeah, I often put my IDE into debug mode to view the properties of something. When it's an object with properties, that's usually all I need (in this case it's a free-form dict, so not helpful). Or if I can, I use AGOL Assistant on an item with the properties I want to emulate (in this case, you have to guess that extract means export). Or I use Google and find other users wandering around in the dark helping each other. But none of those would be necessary if there were even a base level of documentation! Can you tag some people at Esri or forward a link to this thread to show them how frustrating this can be? The screenshot I posted above perfectly illustrates how much documentation is missing.
@davedoesgis I'm having trouble locating the documentation as well. One way is to print the properties of a feature layer collection. A good example of this can be found here:
https://developers.arcgis.com/python/guide/updating-feature-layer-properties/
@JakeSkinner - Where can I find documentation on these options? If I go to the documentation for FeatureLayerCollectionManager, that has the update_definition method, which says it's just like the 'properties' property, but that documentation is missing.
I'd love to know more about this specifically, but in general, I often find myself in cases like this where I'm passing in JSON or a dict and it's real guesswork as to what all the options are. After hitting a dead end on the documentation, I end up googling for an answer, which leads me here to GeoNet or to the samples. Sometimes, these solve the problem, but not always, so I'm wondering if there's a better way. thanks.
I'd assume you follow Jake's example above, but just set it to "Query".
Hello!
What would be the way to add/publish a feature layer without the export capabilities?
Thanks,
Marcelo
That's great, thanks Jake Skinner
