A daily schedule reads your channel, lists every upload, and pulls each video's current title, description, tags, privacy status, and category.\n2. Each field is compared against the snapshot saved on the previous run, and every difference is collected as an old value to new value pair.\n3. Changed fields are appended to a Change Log tab, then the current values overwrite the Snapshot tab so the next run compares against today.\n4. Slack receives a summary of what changed, and stays quiet when nothing changed unless you turn on alwaysNotify.\n\n### Setup steps\n- [ ] Connect a YouTube (Google) OAuth2 credential on the three YouTube nodes.\n- [ ] Enter your channel ID in `Set Audit Options`.\n- [ ] Connect your Google Sheets credential and select your audit spreadsheet in all four Google Sheets nodes.\n- [ ] Add a tab named `Snapshot` and a tab named `Change Log` in that spreadsheet.\n- [ ] Connect your Slack credential and pick the alert channel in `Post Summary to Slack`.\n\n### Customization\nChange the schedule interval, add or remove tracked fields in `Diff Metadata Fields`, or set `alwaysNotify` to true to also post when nothing changed."
