If Else In Dataweave

In this tutorial, we will demonstrate if else conditional expression in dataweave

Input-1

{
    "status": "success",
    "id": 1,
    "employee_name": "Tiger Nixon",
    "employee_salary": 100000,
    "employee_age": 35
}

Input-2

{
    "status": "success",
    "id": 1,
    "employee_name": "Tiger Nixon",
    "employee_salary": 10000,
    "employee_age": 55
}

Input-3

{
    "status": "success",
    "id": 1,
    "employee_name": "Tiger Nixon",
    "employee_salary": 23000,
    "employee_age": 35
}

Input-4

{
    "status": "success",
    "id": 1,
    "employee_name": "Tiger Nixon",
    "employee_salary": 100000,
    "employee_age": 65
}

Now we will write a dataweave expression and manipulate the if the employee is eligible for discount on the basis of Input payload

Create a sample mule application in anypoint studio and configure the listener to test the application

Drag and drop the transform message and write dataweave expression

%dw 2.0
output application/json
---
{
	isEligbleForDiscount: if(payload.employee_salary > 50000  and payload.employee_age <50) false
	else if(payload.employee_salary < 50000  and payload.employee_age >50) true
	else if(payload.employee_salary > 50000  and payload.employee_age >50) false
	else if(payload.employee_salary < 50000  and payload.employee_age <50) true
	else false
}

Deploy the application and test with all the input payload
