How to setup postMessage

I am working with an embedded Metabase report. What I'm looking to do is make the iFrame the full height of the report. I have found the documentation about this which suggests using postMessage to send a “frame” message from Metabase to your app. The problem I'm having is that I cannot find where to setup the postMessage within Metabase. Any help would be greatly appreciated.

Hi @bkelley-idearoom
There's nothing to setup, the postMessage is already active, when using FullApp embedding, which is available for Pro/Enterprise plans:

If you are using Signed Embedding, then there's separate functionality for that:

Thank you for the reply! Turns out we were using signed embedding and the iFrame Resizer worked great!
