```auto
msg.payload= {
    "body": {
        "roomId": "Y2lzY29zcGFyazovL3VzL1JPT00vMmEzYzRjMDAtNTliOC0xMWU5LWEzZjktNGRjNmI1MmU3MTE3", "text": Network Device Details: '\n' Device 1: Host Name- "+host0+" , Management IP- "+host0IP+" , Reachability Status- "+host0S+"
    }

if you are posting code it is far easier to read if you format it, please follow the advice in this post: [How to share code or flow json](https://discourse.nodered.org/t/how-to-share-code-or-flow-json/506?u=ukmoose)

The following is incorrect. Look at the quotes...

```auto
"text": Network Device Details: '\n' Device 1: Host Name- "+host0+" , Management IP- "+host0IP+" , Reachability Status- "+host0S+"

```

compared to...

```auto
"text": "Network Device Details: '\n' Device 1: Host Name- "+host0+" , Management IP- "+host0IP+" , Reachability Status- "+host0S+"

```

assuming host0 host 0IP and host0S are variables?

yes they are variables,

```auto
var host0 = msg.payload.response[0].hostname;
var host0IP = msg.payload.response[0].managementIpAddress;
var host0S = msg.payload.response[0].reachabilityStatus;

```
