How to write parameter name with space in it? Custom Integromat apps

Question

Api sends me a response with "Joined at" parameter, and I cant do anything with it because of the space " ", but that paramter is vital for one trigger in my Integromat app.

"trigger": {
    "id": "{{item.id}}",
    "date": "{{item.attributes.Joined at}}",
    "type": "date",
    "order": "desc"
}

Response example

Answer 1

You can use backticks to retrieve collection properties, as explained in the docs.
The expression will look like this: "date": "{{item.attributes.`Joined at`}}"
