ACI REST Programming two Physical domain in one rest POST command

How to put in two Physical domains or several in one POST command , manage to copy and paste from the ACI api toll  tool. Is it regarding the object model or is it even possible to put it in more actions, one is ok and works but when need one more it´s just do one and stops. 

Ex:

will do the fist but not the second .
