Hi all — I have code to create a custom object, which works, but I actually already have a custom object in my system called Invoice. I guess what I really want to create is a new instance of a custom object (in this case, I want to create new invoices). Does anyone have any examples of creating instances of custom objects? And perhaps an example of a custom object instance that references another object instance? In my case, my setup is that an Opportunity has many Invoices.
Could this even be done using the REST API? I seem to have been misunderstanding the terminology a bit and confused creating a new custom object type with a new custom object instance.
