Oracle API Platform Cloud Service - Groovy Script to Check Payload and SOAP Header

Steps to Get Payload Data: 

def apiRequestBody = context.ApiRequest.getBody().asString()

def soapEnv = new XmlSlurper().parseText(apiRequestBody)

def clientSystem = soapEnv['Header']['XXHeader']['XXSystem'].toString()

if ( clientSystem != 'SNV-Vijaya' )

{

  throw new oracle.apiplatform.policies.sdk.exceptions.PolicyProcessingException('Forbidden', 403, 'Access Denied')

}

def sourceEnv = soapEnv['Header']['XXHeader']['XXEnvironment'].toString()

def corrId = soapEnv['Header']['XXHeader']['XXId'].toString()

Set Custom Header Values: 

context.ServiceRequest.setHeader("x-intg-source-system", clientSystem )

context.ServiceRequest.setHeader("x-intg-source-env", sourceEnv)

context.ServiceRequest.setHeader("x-intg-corrid", corrId)
