+## Все эндпоинты имперсонации
+
+| Метод | Путь | Описание |
+|-------|------|----------|
+| `POST` | `/api/v1/impersonation/start` | Начать имперсонацию |
+| `POST` | `/api/v1/impersonation/end` | Завершить имперсонацию |
+| `POST` | `/api/v1/impersonation/extend` | Продлить сессию имперсонации |
+| `GET` | `/api/v1/impersonation/status` | Статус текущей имперсонации |
+| `GET` | `/api/v1/impersonation/history` | История своих имперсонаций |
+| `GET` | `/api/v1/impersonation/history/all` | История имперсонаций всех админов |
+
+## Формат ImpersonationStartRequest
+
+```json
+{
+  "type": "user",
+  "entity_id": "UUID контакта (contactId из userInfo)",
+  "reason": "описание причины"
+}
+```
+
+- `entity_id` — **UUID таргета** (кого имперсонируем), не свой
+- `type` — всегда `"user"`
+
+## curl-команды
+
+### Начать имперсонацию
+
+```bash
+curl --http2 -X POST \
+  -H "Authorization: Bearer $TOKEN" \
+  -H "Content-Type: application/json" \
+  -H "Accept: application/json" \
+  "https://auth-api.ngcloud.ru/api/v1/impersonation/start" \
+  -d '{"type":"user","entity_id":"UUID_таргета","reason":"тест"}'
+```
+
+### Статус
+
+```bash
+curl --http2 \
+  -H "Authorization: Bearer $TOKEN" \
+  -H "Accept: application/json" \
+  "https://auth-api.ngcloud.ru/api/v1/impersonation/status"
+```
+
+### История
+
+```bash
+curl --http2 \
+  -H "Authorization: Bearer $TOKEN" \
+  -H "Accept: application/json" \
+  "https://auth-api.ngcloud.ru/api/v1/impersonation/history"
+```
+
+### Продлить
+
+```bash
+curl --http2 -X POST \
+  -H "Authorization: Bearer $TOKEN" \
+  -H "Accept: application/json" \
+  "https://auth-api.ngcloud.ru/api/v1/impersonation/extend"
+```
+
+### Завершить
+
+```bash
+curl --http2 -X POST \
+  -H "Authorization: Bearer $TOKEN" \
+  -H "Accept: application/json" \
+  "https://auth-api.ngcloud.ru/api/v1/impersonation/end"
+```
+
+## Примечания
+
+- Требуется роль IAM-админа или право на объект `impersonation`
+- `--http2` обязателен для обхода ddos-guard
+- Стенды: `auth-api.ngcloud.ru` (prod), `auth-api-test.ngcloud.ru` (test), `auth-api-dev.ngcloud.ru` (dev)
