Hello everyone! I'm really struggling to find a way to set the value of a custom segment field on a record using Netsuite's REST API. My request is coming back as successful but the field stays empty... I've been trying a bunch of things including

{"cseg_cust_segment_id": VALUE_ID}

and

{"cseg_cust_segment": {"id": VALUE_ID}}

but nothing seems to work. If someone could point me in the right direction that would be greatly appreciated 🙂

• Could you confirm if you are able to set the field from NetSuite's User Interface? • Did you try to set it using Administrator Role from Rest API?

I can confirm I'm able to set it from the GUI. I'll try to play around with the permissions and let you know, thanks !
