Pull ticket and 1 custom field response?

Good afternoon,

I am trying to make an API Call that will give me an answer on a ticket number, but only return 1 of the custom fields as a result.

I know I can run;

Zendesk - Individual Ticket Get
https://domain.zendesk.com/api/v2/tickets/32099.json 

This will pull the ticket number 32099 and all it's details. Though I wanted to only get the custom field of 360000081815 in my system.

I can call it by itself, https://domain.zendesk.com/api/v2/ticket_fields/360000081815.json, but of course that just tells me the type of field it is.

I was hoping I could combine both API's to pull a repose of Ticket 32099 and just get back that custom field? 

Part of the issue is that when I pull just that ticket, all of the custom fields come in under a custom_field and hard to seperate it from the 49 ID's that come back.

Thanks.
