Hey@peterchai89,You can definitely update custom properties using the new APIs. The problem you’re running into here is how you’re structuring your API request payload. You need properties to be nested under attributes for this to work properly. Here’s an updated payload example:{ "data": {  "type": "profile",  "attributes": {   "email": "ptctech@gmail.com",   "phone_number":"+61431111232",   "first_name": "Peter123",   "last_name": "Chai",   "properties": {    "membership": "GOLD"  }  }    }}There’s also an API endpoint you can use to create or update a profile in a single request here, if that’s desired:https://developers.klaviyo.com/en/reference/create_or_update_profile
