you can use the HTTP node to post to a slack webhook. steps:
1. in slack go to api.slack.com/apps and create an app
2. add an "incoming webhook" and pick the channel
3. copy the webhook URL
4. in your workflow add an HTTP node after your condition (where you check for high priority)
5. set it to POST to the webhook URL with a JSON body like: {"text": "New high-priority submission from [name]"}
takes about 5 minutes to set up. the slack app creation is the only slightly annoying part but you only do it once
awesome this is exactly what i needed. way simpler than i expected. going to set this up today
protip: you can make the slack messages much richer by using blocks instead of plain text. slack has a block kit builder (app.slack.com/block-kit-builder) where you can design messages with buttons, sections, images etc. just paste the block JSON into the HTTP node body
we use this to send formatted cards with the submission details, a link to the record, and approve/reject buttons
the block kit approach is great. we also include the form submission data in the slack message so the team can see what came in without leaving slack. saves a ton of context switching
