Has Anyone Used Fusion to Convert a Proof's Custom Email Message into the First Proof Comment?

Hi everyone,

I'm exploring a Fusion use case and would love to hear if anyone has tackled something similar.

When creating a proof, users often enter important instructions in Email Notification → Add Custom Message. The challenge is that once the proof is created, those instructions aren't easily accessible within the proof itself.

Ideally, we'd like to build a Fusion scenario that:

1. Detects a newly created proof.
2. Retrieves the custom email message.
3. Automatically posts that message as the first comment in the proof.

This would preserve review intent and project-specific instructions directly within the proof, even if the original email is deleted or lost.

My main question:

Does the Workfront Proof API expose the value entered in Email Notification → Add Custom Message → Message?

If so, has anyone successfully used Fusion to retrieve that value and create a proof comment from it? I'd also be interested in hearing what modules, API calls, or overall framework you used.

Any insights or examples would be greatly appreciated. Thanks!
