I have json data something like this:

{

    "id": "saldfjsaf9s7dflksdf435345h",

    "description": "Hello World",

    "image": "<BYTE STREAM CONTAINING IMAGE>"

}

I send this data in the body of a post request to a webhook.

What I would like to do is:

1. Send an email. I want to extract the values of “id” and “description” to be part of a message in the mail body
2. Extract the content of the “image” value and save it to a file

My questions are:

1. Should I use a “catch hook” or a “catch raw hook” webhook?
2. How do I reference the individual sub elements in the JSON data object from the webhook in the email body?
3. What action would you suggest to extract the content of the “image” sub element and save that to a file?

If someone could tell me if this is possible and guide me in the right direction, it will be highly appreciated, thanks ;-)
