Pass response value of one service to other(With Authentication)?

Sorry Marek,still not clear.

Let me elaborate the problem statement.

I need to test 2 services .Pass response of one service to input to other.
Eg:Service1 and Service2

Service1 has 3 parameters & Service 2 has 2 parameters.

Service1:
modulename:Create
name:abc

When i send the request(POST) to Service1,in response i’ll get a auto generated number(Eg:1234),now i want to pass this value(1234) to Service2 has a input value along with other parameters
Service2:
modulename:delete
number:1234

1)If i get a complete working code then it will be helpful.
2)How can we pass dynamic value to HTTP body as a parameter.

Thanks,
Abhi
