That's cool! I've thought about doing this with organization webhooks. I assume your code is pulling on a timer or something similar?
Yah the Zapier thing used webhooks from GHA and events from Amplify but it was a pain to integrate & maintain. Fooboard polls the GHA & Amplify logs and pattern matches, so you can create whatever statuses the logs will support and no need to touch your workflows.
So yes polling but it's pretty smart about timing so it's responsive without burning your request quota.
