# Create a task

`POST /v1/tasks`

Creates a new task record. The `$title` and `$status` fields and the `$assignedTo` relationship are required.

If `$createdBy` is omitted it defaults to the authenticated user, or to a workspace admin for workspace-scoped auth. The `$note` relationship is read-only — manage notes via their own relationships.

Supports idempotency via the `Idempotency-Key` header.

Required: `$title` (string) and `$status` (one of `TODO`, `IN_PROGRESS`, `COMPLETE`, `CANCELLED`). Call the <u>[definitions endpoint](/api/resources/task/methods/definitions)</u> to discover the available fields.

  - `relationships` union, required — Relationships to set on the new task.

Call the <u>[definitions endpoint](/api/resources/task/methods/definitions)</u> to list available relationship keys.
