# Scrum backlogs

**Scope:** `task` | **Auth:** `X-Api-Key`

| Method | Path | Bitrix24 method | Body |
|---|---|---|---|
| POST | `/v1/scrum/backlogs` | `tasks.api.scrum.backlog.add` | `{ "groupId": 7, "createdBy": 3 }`; `groupId` is required |
| PATCH | `/v1/scrum/backlogs/:id` | `tasks.api.scrum.backlog.update` | Any of `groupId`, `createdBy`, `modifiedBy` |
| DELETE | `/v1/scrum/backlogs/:id` | `tasks.api.scrum.backlog.delete` | None |

`:id` is the backlog ID, not the group ID. Fields are passed to Bitrix24 as `fields`; its result is returned in `data` without reshaping. Create and update return a backlog object; delete returns the controller result. Changing the group or deleting a backlog can affect task placement; Bitrix24 decides its restrictions and refusals.
