Hi,

I want to get Webhooks from my Cisco Webex Teams Account without exposing my Node Red installation.

Therefore I registered to node-red-contrib-webhookrelay and I am already receiving messages.

```auto
{"id":"Y2lzY29zcGFyazovL3VzL1dFQkhPT0svMGY1MDBmNTEtMjE5Ni00MWEwLTk0MDUtMmIyNTJkMGIxOGRk","name":"NODE-RED:7a067edd.a87e3","targetUrl":"https://my.webhookrelay.com/v1/webhooks/xyz","resource":"messages","event":"created","orgId":"xyz","createdBy":"xyz","appId":"xyz","ownedBy":"creator","status":"active","created":"2020-02-02T12:32:42.365Z","actorId":"xyz","data":{"id":"this-id-i-want-to-extract","roomId":"xyz","roomType":"group","personId":"Y...

```

I need the second ID, the ID with the value "this-id-i-want-to-extract" as payload.

It looks like that body is a JSON string. Have you tried a change node to move the `msg.payload.body` to `msg.payload`, followed by a JSON node? Afterwards, you put in a debug node again to see how the object is formatted, considering it is a valid json to start with. ~~Looking at the output it could also be that it outputs several JSON objects one after another, but I can't say that for sure from this limited screenshot.~~ Start there, I'd say.  
Okay, I spoke too soon, you have the object mostly included in your post. It's a single JSON object, as text. So after the JSON node you can access the value you need as `msg.payload.data.id`.
