# Processing Rest2Soap Response with JsonSlurper When Identity Data Service Returns Empty Response

> Processing JSON response from REST service and converting to SOAP format, managing error cases

## Groovy Script

```groovy theme={null}
import groovy.json.JsonOutput

def parser = new groovy.json.JsonSlurper()
def jsonResp = parser.parseText(responseBodyTextToClient)

String adBilgisi = jsonResp.BilesikKutukBilgileri.TCVatandasiKisiKutukleri.KisiBilgisi.TemelBilgisi.Ad
String soyadBilgisi = jsonResp.BilesikKutukBilgileri.TCVatandasiKisiKutukleri.KisiBilgisi.TemelBilgisi.Soyad

if (adBilgisi == null || adBilgisi.isEmpty()) {
    statusCodeToClient = 503
    def pretty = JsonOutput.prettyPrint(JsonOutput.toJson([
        ad: "",
        soyad: ""
    ]))
    responseBodyTextToClient = pretty
} else {
    def pretty = JsonOutput.prettyPrint(JsonOutput.toJson([
        ad: adBilgisi,
        soyad: soyadBilgisi
    ]))
    responseBodyTextToClient = pretty
}
```

## Explanation

This script performs the following operations:

1. **Parsing JSON Response**: Parses the JSON response coming from REST service using `JsonSlurper`.
2. **Data Extraction**: Extracts name and surname information from JSON structure.
3. **Control and Conversion**:
   * If name information is empty or null, returns an empty JSON response with HTTP 503 status code.
   * If name information exists, returns a JSON response containing only name and surname information.

## Usage Scenario

This script processes the response from identity verification service:

* Returns error code in case of empty response
* Filters and returns only necessary fields in case of valid response

<Note>
  This script should be run on the response line (Response Policy) because it uses the `responseBodyTextToClient` variable.
