Realizo la configuración en el postman y se conecta bien

Pero cuando lo valido en REST Debugger me sale error, no se que me falta configurar, o bueno no se como agregar el json porque va sin name

La verdad no se como configurar el Json para que me funcione.
No se cual sea el equivalente del Body/raw en el debugger
