# Create Task

`POST /createTask`

| Field | Type | Required | Notes |
|---|---|---|---|
| `clientKey` | string | yes | API key in the body |
| `task` | object | yes | Task parameters |
| `task.type` | string | yes | Case-sensitive type string |
| `callbackUrl` | string | no | Public HTTP(S) URL only. At-least-once delivery; dedupe with `Idempotency-Key` or `X-Captcha-Callback-Id`. |

`status` is `processing`, `ready`, or `failure`. Akamai v1 multi-round `/submit` is **not** a general API — see [AntiAkamaiSensorTask](/docs/task-types/anti-akamai-sensor).
