Code snippet to extract pdf meta data - SOLVED

I’m not a coder and wondered if someone might help me with a snippet of code to extract the ‘clientID’ from the meta: object as shown.

An hour ago I didn’t know what a webhook was and having jumped that hurdle I now find myself having to learn node.js to be able to use the data I’ve successfully got into pipedream.

It’s a little too much for one day. Hopefully I have explained this clearly - probably don’t have the exact language available to me to explain what I want.

Thanks in advance for any help kindly offered.
