Hi, I hope this finds you well.  
I'm GETTING an Access Token by calling a RestAPI through an HTTP request, then I'm extracting that Access Token to a msg.payload, I'd like to know how I can pass that Bearer Token to a Function Node.  
See below screenshot.

You can concatenate strings and variables using The `+` operator  
e.g.

```auto
{
    "Content-Type": "application/json",
    "authorization": "Bearer " + msg.payload
}

```
