https://community.esri.com/t5/arcgis-api-for-python-questions/create-domain-with-python-api-script/m-p/1178271#M7438 <P>My apologies that my question comes with no, I have been asked to transfer data to a feature layer by importing a csv using a python script. I have that working fine but the business has now requested ddl's on the form the csv populates, now so far my attempts were creating the domain on ArcGis online, but when I update the csv data the domain gets deleted, I'm not usually developing ArcGis operability and I'm stumped as to how this really works, any assistence or tutorials will be greatly appreciated.</P> Mon, 30 May 2022 08:40:48 GMT BrianShaw 2022-05-30T08:40:48Z https://community.esri.com/t5/arcgis-api-for-python-questions/create-domain-with-python-api-script/m-p/1178271#M7438 <P>My apologies that my question comes with no, I have been asked to transfer data to a feature layer by importing a csv using a python script.
