It can be started manually for testing or by a PagerDuty resolved-incident webhook. It normalizes the incident payload, retrieves incident details and timeline events, builds a review-ready postmortem draft, creates a Confluence page, notifies the incident owner in Slack, and logs the result to Google Sheets.\n\n### Setup steps\n\n- [ ] Configure the PagerDuty resolved-incident webhook to call the n8n webhook URL.\n- [ ] Add PagerDuty API credentials to the incident details and timeline request nodes.\n- [ ] Update `pagerduty_base_url`, `confluence_base_url`, `confluence_space_key`, and `confluence_parent_page_id` in `Set Config Variables`.\n- [ ] Add Confluence credentials with permission to create pages in the selected space.\n- [ ] Add Slack OAuth credentials with permission to post messages to the review channel.\n- [ ] Optional: add Google Sheets OAuth credentials and set the spreadsheet ID for the postmortem log.\n\n### Customization\n\nAdjust the postmortem structure in `Generate Postmortem Draft`, change the Confluence destination variables, and customize the Slack message or Google Sheets fields to match your incident review process. Keep human review before publishing incident reports."
