The Timeline schema lists all the JSON fields and objects required to create a Timeline or a Timeline template using the Create timeline API.

All column, dropzone, and filter fields must be ECS fields.

This screenshot maps the Timeline UI components to their JSON objects:

Title (title)
Description (description)
Global notes (globalNotes)
Time filter (dateRange)
Dropzone (each clause is contained in its own dataProviders object)
KQL bar mode (kqlMode)
KQL bar query (kqlQuery)
Event types included in Timeline results (eventType)
Additional filters (filters)
Column headers (columns)
Event-specific notes (eventNotes)
