Programmatically update hosted feature layer in AGOL

JoeSaltenberger — Thu, 10 Oct 2019 16:48:34 GMT

I am wondering what are the options for updating a hosted feature layer in AGOL. For context, I will be hosting point layer with about 500 features that will be updated nightly from a scheduled task. The initial publishing of the layer does not need to be programmatic, but the nightly update does.

I have been looking into using the REST API update/delete/create endpoints for doing these nightly updates.

My question is, are there any other options for performing these updates outside the REST API? I see there is also a Python API and Native SDKs. Are those libraries using the REST API under the hood?

Thanks.

Hi Joe Saltenberger‌

The ArcGIS API for Python does use the REST API under the hood. This blog goes into that in a little more depth: ArcGIS API for Python Core Concepts Part 1: Python, APIs, and REST

There are some good resources on using the Python API to accomplish the workflow here:

Hope this helps,

The following code works for me in order to update hosted feature layer (i.e., overwrite the data):

from arcgis.gis import GIS
source = GIS("http://yourorganization.maps.arcgis.com", "username", "password", verify_cert=False)
csv = source.content.get('a4e4587122354eb2847d461263e3ccb7')
csv.update({}, r'C:\TEMP\data.csv')
csv.publish(overwrite=True)‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

Hi william,

I am trying to use your code to update a hosted line feature layer but I keep getting some error. I have used the same code mentioned above changing the URL, username, password, item ID, and csv file reference path. I have added a screenshot of the error message. Could you please help me to find my mistake? I want to update a hosted feature layer with a csv file.
