API Post request question

The API instructions from a tool I am trying to use look like this:

curl --location --request POST https://api.writer.com/v1/graphs/question \
--header "Authorization: Bearer <token>" \
--header "Content-Type: application/json" \
--data-raw '{"graph_ids":[{id number}],"subqueries":false,"question":"prompt question here","stream":false}

I have an app id and key name and key which I assume I need to use to get the Bear token?

…and the body of the request is the stuff below the header?

I have tried a few of the standard nodes but can’t get it to work. Does anyone have an example to share to show me what I am doing wrong to get this up?
