Hello,
Thanks for the reply! I'm a little bit confused with #3 and 4.
The Input for my Compose action is the Body from the email.
Should the URI for the HTTP request be the Compose Output (as shown in the screenshot)?
The download URLs in the email are all different each time, but they all start with "https://42y7l4ikac.execute-api.us-east-1.amazonaws.com/default/download"
