Well first thing to note is that the payload is a string - ![image](https://us1.discourse-cdn.com/flex026/uploads/nodered/original/2X/4/427a84dd744e9c814230ea04df850f4e93ec1e0b.png)  
that looks like a JSON string of a javascript object. So the best thing to do is to pass it through a `JSON` node to convert it into an object... (then to debug to see what it contains again).

Then read - [https://nodered.org/docs/user-guide/messages](https://nodered.org/docs/user-guide/messages) which will give you clues on how to pick out the parts you may want from there.
