REST to Create Ticket and Users from Customer List

Greetings,
I can populate my Users from my customer list through the REST Interface.

I have some custom fields like IDNumber and others…

I’ve tried like that:

CF.{IDNumber} = 999888
and
CF- IDNumber = 999888
And
CF-‘IDNumber’ = 999888

The user was created! But were not filled. I have the same problem to create
ticket by REST.

Thanks for All.
Marcelo Calado.
