Preview creative after Slack approval
When a linked creative receives its approval reaction, render the URL as an image so the approved version is easy to review.
Trigger

Action
HTML to Image
Tool to convert base64-encoded html to an image. use when you need to render raw html or a url into png, jpeg, or webp after content load.
Why this helps
The final approved link can be buried in feedback, making it hard to identify which version is ready for a visual check.
- Connects a visible approval signal to a visual preview.
- Makes the approved URL easier to identify and inspect.
- Cuts down on manual screenshot capture.
Setup
Build it in a few focused steps.
- 1Connect Slack and Cloudlayer to Notis once in the portal.
- 2Create the automation from the portal or ask Notis conversationally.
- 3Write one instruction asking Notis to render the public creative URL as an image when the selected approval reaction is added.
- 4Select the Slack message reaction added trigger and the channel for run reports.
- 5Test with one real creative link and the team's approval reaction.
Questions about this workflow
Does the reaction itself identify the URL?
The message should include the URL to render, and the instruction should specify the approval reaction.
Can Cloudlayer preview an internal page?
The linked page needs to be reachable by Cloudlayer for rendering.
