Suppose application A calls application B:

1. Is this how it is written in A? ：  
var request = webOS.service.request(‘luna://com.webos.applicationManager’, {  
method: ‘launch’,  
parameters: {  
id: ‘com.domain.app2’,  
params: {  
customParam1: ‘param1’,  
customParam2: ‘param2’,  
},  
},  
onSuccess: function (inResponse) {  
console.log(‘The app is launched’);  
// To-Do something

2. How to receive the parameters of A in B?
