API testing - POST request with JSON Body parametrization

Hi All,
I need help to automate the Request body of an API POST method. I am having trouble with passing variables to the request body.

/* Request Body looks like this:*/


“customerName” : “string”,
“customerAddress1” : “string”,
“customerAddress2” : “string”

My script looks like this:

// enrollmentAPI_submitenrollment from object Repository

def request = ((findTestObject(‘enrollmentAPI_submitenrollment’)) as RequestObject)

/* Capturing data from Excel sheet rows (i have a loop to increment the rows in excel but thts not relevent to the issue so not providing tht info*/

def Name= findTestData(“ExcelData-1”).getValue(“ColumnName”,1)
def Address1= findTestData(“ExcelData-1”).getValue(“ColumnAddress1”,1)
def Address2= findTestData(“ExcelData-1”).getValue(“ColumnAddress2”,1)

def CustName= “customerName: ${Name}”
def CustAdd1= “customerAddress1: ${Address1}”
def CustAdd2= “customerAddress2: ${Address2}”

String body = “{${-> CustName},${-> CustAdd1},${-> CustAdd2}}”


But this returns a body that looks like :

{ customerName : ${Name}, customerAddress1 : ${Address1}, customerAddress2 :${Address2}}

However when i submit the request like this:

request.setBodyContent(new HttpTextBodyContent(body, ‘UTF-8’, ‘application/json’))

im receiving a 400 error saying tis a bad request.

im trying to achieve a post request body like this:

{ “customerName” : “${Name}”," customerAddress1" : “${Address1}”, “customerAddress2” :“${Address2}”}

How can i get this? how can i parametrize just the names in the body to do the automation?

Plz advise


I defined the variables in the below fashion and it helped me to get the body in JSON format.

def CustName= ““customerName”: “${Name}””
def CustAdd1= “\“customerAddress1”: “${Address1}””
def CustAdd2= ““customerAddress2”: “${Address2}\””

everything else stayed the same.
