Looking at the customer XML, i can see the 'addressbook' object. Anyone know where i'd see the script that creates the output of this? There's a couple custom fields we added that aren't showing within this and i just wanted to see how easy it'd be to add them in.

you dont have any control of the xml, its just an xml representation of the customer that netsuite can generate

Ok - so if the xml is a representation of the customer, I can see the custom fields within the customer object on the UI, but not in the xml

you are probably more interested in https://system.netsuite.com/app/common/address/address.nl?id=18915&xml=T

how do i access that in NetSuite?

edit button on the addressbook sublist, which should match the url i gave

So, you can see here that the custom fields are present in the UI - shipping email and external ID

what does the xml look like?

ah, they show in the xml of the address specifically

im not sure what kind of weird integration tool you are using that uses this information, but ive only seen the xml from the xml parameter used in the ui

this is just in NetSuite

that should be suitetalk soap based
