# Create a HumanTask

`POST /v1/human_tasks`

Creates a HumanTask in the Organization's existing staff task queue. Look up assignable StaffMembers with `GET /v1/staff_members`.

**Required API scopes:** `human_tasks.create`

## Parameters

- `Idempotency-Key` (header, `string`) (required) - Client-generated idempotency key. Required for every POST/PATCH write. Replay of the same key with the same body returns the stored response with an `Idempotency-Replayed: true` header. Same key + different body returns `422 idempotency_key_reused`. A duplicate that arrives while the first request is still in flight returns `409 idempotency_conflict` with `Retry-After: 1`.

## Request body (`application/json`)

- `object`
  - `assignees` (`array`) - The people to assign to the HumanTask. Each object requires `assignee_type` and `assignee_id`. Currently only `staff_member` is supported.
    - `items` (`object`)
      - `assignee_id` (`string`) - format: `uuid`; The identifier of the assignee. For `staff_member`, use an identifier from `GET /v1/staff_members`.
      - `assignee_type` (`string`) - enum: `staff_member`; The type of assignee. Currently only `staff_member` is supported.
  - `content` (`string`) - The description of the work to complete.
  - `due_date` (`string`) - format: `date`; The date by which staff should complete the HumanTask.
  - `is_remindable` (`boolean`) - Whether Carebit can send reminders when the HumanTask becomes due.
  - `is_urgent` (`boolean`) - Whether the HumanTask should be marked as urgent.
  - `patient_id` (`string | null`) - format: `uuid`; The optional Patient associated with the HumanTask.

### Example

```json
{
  "assignees": [
    {
      "assignee_id": "00000000-0000-4000-8000-000000000021",
