I have a HTTP listener that I am sending a JSON post body with. 

```
{
"recipient":"bob@example.com",
"subject":"this is a test subject",
"body":"this is a test body email"
}

```

I am trying to pull those individual parameters out in the next flow, but it errors instead! 

The result I am looking to achieve is "bob@example.com" being taken as an input for the next action 

I've tried things like 

```
"@{triggers().outputs.body.Content.recipient}"

```

and various variations of, but I suspect I'm missing something! 

**edit to add**

I am currently sending the post request via Powershell, though it will ultimately be over c# 

```
$a = @"
{"recipient":"bob@example.com","subject":"this is a test subject","body":"this is a test body email"}
"@

Invoke-WebRequest -Uri     https://httplistenerc743421edf234899a1315aa38c6398bc.azurewebsites.net/listen -Method POST -Body $a

```
