Orbs contracts can call other orbs contracts as part of the execution logic. We call this action a service call.
To call other contracts from your contrat, you must to import the service library:
import (
    "github.com/orbs-network/orbs-contract-sdk/go/sdk/v1/service"
)
The service library exposes a single function called CallMethod. CallMethod is used to call the external contract, which must be deployed on the same virtual chain of the Orbs blockchain.
CallMethod(serviceName string, methodName string, args ...interface{}) []interface{}
This function received the following arguments:
serviceName - The contract name
methodName - The method to call in that contract
args - The variadic parameter for the method arguments 
The return value contains the array of the result of the function execution.
