I’m using the Object Definition tab/tool in the [developers.hubspot.com](http://developers.hubspot.com) api docs.  
I am using the create new schema section to create my code.  
I’ve completed all sections and there is no section to enter the primary display property. Of course when I call, the error response is invalid primary display property.  
I’m not able to edit it directly in the Request code window either. There I see it set as: “primaryDisplayProperty”: “my\_object\_property”,

Is something wrong with the Object Definition tool?  
Or what do I need to do to get it to give me the option to edit the primary display property?

I have just discovered the ‘See all params’ button.  
That did it!

Solved my own first issue 🙂
