Automate postmortem document generation from incident.io incident data via the API

Steps

1. Retrieve a resolved incident with full detail: GET https://api.incident.io/v2/incidents/{id} including the timeline, role assignments, and custom fields
2. Fetch incident updates: GET https://api.incident.io/v2/incident_updates?incident_id={id} to reconstruct the chronological timeline of status changes and communications
3. Fetch action items: GET https://api.incident.io/v2/incident_action_items?incident_id={id} to capture follow-up tasks generated during the incident
4. Assemble a structured postmortem document from the fetched data, populating sections for timeline, impact, root cause, contributing factors, and action items
5. Create a follow-up task in your project management tool (e.g., POST to Jira or Linear API) for each action item, referencing the incident ID for traceability
6. Optionally trigger a postmortem workflow via PATCH to mark the incident as in_post_incident_review status and assign the postmortem owner using role assignments
