-## 구현 필요사항
+## 최종 해결 (2025-09-08)
 
-### 1. robeing-gateway/app/main.py 수정
-```python
-@app.post("/slack/interactive")
-async def slack_interactive_proxy(request: Request):
-    # URL encoded payload 파싱
-    form_data = parse_qs((await request.body()).decode())
-    payload = json.loads(form_data.get('payload', [''])[0])
-    team_id = payload.get("team", {}).get("id")
-    
-    # DB에서 토큰 조회
-    # 중요: FastAPI가 헤더를 소문자로 변환하므로 get("x-slack-signature") 사용
-    # headers = {"X-Slack-Signature": get("x-slack-signature"), ...}
-```
+### 1. robeing-gateway/app/main.py:552-587
+- /slack/interactive 엔드포인트 추가
+- request.headers.get("x-slack-signature") - 소문자 필수
+- request.headers.get("x-slack-request-timestamp") - 소문자 필수
+- content=body로 원본 전달
+- X-Slack-Bot-Token 헤더로 토큰 전달
