本页将介绍使用 Devin API 的常见端到端工作流程。每个流程都包含完整的 API 调用顺序及代码示例。有关各个端点的详细信息，请参阅相关的 API 参考页面。

​
设置

在运行任何示例之前，请先设置以下环境变量： 
# 必填：你的服务用户 API key（以 cog_ 开头）
export DEVIN_API_KEY="cog_your_key_here"

# 必填：你的组织 ID（在 Settings > Service Users 中查找）
export DEVIN_ORG_ID="your_org_id"

​
快速开始：从 API key 到首次会话

最常见的工作流程——完成身份验证、查看你的账户，并创建你的第一个会话。

​
步骤 1：验证你的凭据

此步骤使用企业作用域端点。组织作用域的服务用户可以跳到步骤 3——你已经从 Settings 页面知道了你的 org ID。
curl "https://api.devin.ai/v3/enterprise/self" \
  -H "Authorization: Bearer $DEVIN_API_KEY"
响应： 
{
  "user_id": "svc_abc123",
  "email": "my-service-user@devin.ai",
  "name": "CI Bot"
}

​
步骤 2：列出你的组织

企业版服务用户可以列出所有组织： 
curl "https://api.devin.ai/v3/enterprise/organizations" \
  -H "Authorization: Bearer $DEVIN_API_KEY"
组织作用域的服务用户已经知道其 org ID（可在创建该密钥的 Settings > Service Users 页面上找到）。

​
步骤 3：创建会话

curl -X POST "https://api.devin.ai/v3/organizations/$DEVIN_ORG_ID/sessions" \
  -H "Authorization: Bearer $DEVIN_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"prompt": "Create a Python script that analyzes CSV data"}'
响应： 
{
  "session_id": "devin-abc123",
  "url": "https://app.devin.ai/sessions/devin-abc123",
  "status": "running"
}

​
步骤 4：轮询获取事件

通过轮询消息来监控会话： 
curl "https://api.devin.ai/v3/organizations/$DEVIN_ORG_ID/sessions/devin-abc123/messages" \
  -H "Authorization: Bearer $DEVIN_API_KEY"

​
完整的 Python 示例

import os
import time
import requests

API_KEY = os.environ["DEVIN_API_KEY"]
ORG_ID = os.environ["DEVIN_ORG_ID"]
BASE = "https://api.devin.ai/v3"
HEADERS = {"Authorization": f"Bearer {API_KEY}"}

# 1. 验证凭据
me = requests.get(f"{BASE}/enterprise/self", headers=HEADERS)
me.raise_for_status()
print(f"Authenticated as: {me.json()['name']}")

# 2. 创建 session
session = requests.post(
    f"{BASE}/organizations/{ORG_ID}/sessions",
    headers={**HEADERS, "Content-Type": "application/json"},
    json={"prompt": "Create a Python script that analyzes CSV data"}
).json()
print(f"Session: {session['url']}")

# 3. 轮询直至完成
while True:
    status = requests.get(
        f"{BASE}/organizations/{ORG_ID}/sessions/{session['session_id']}",
        headers=HEADERS
    ).json()["status"]
    print(f"Status: {status}")
    if status in ("exit", "error", "suspended"):
        break
    time.sleep(10)

​
下载会话附件

获取会话生成的文件 (日志、截图、生成的代码等) 。

​
步骤 1：获取会话

curl "https://api.devin.ai/v3/organizations/$DEVIN_ORG_ID/sessions/$SESSION_ID" \
  -H "Authorization: Bearer $DEVIN_API_KEY"

​
步骤 2：列出附件

curl "https://api.devin.ai/v3/organizations/$DEVIN_ORG_ID/sessions/$SESSION_ID/attachments" \
  -H "Authorization: Bearer $DEVIN_API_KEY"
响应： 
{
  "items": [
    {
      "attachment_id": "att_123",
      "name": "output.py",
      "url": "https://..."
    }
  ]
}

​
步骤 3：下载

使用附件响应返回的 url 可直接下载文件。

​
完整的 Python 示例

import os
import requests

API_KEY = os.environ["DEVIN_API_KEY"]
ORG_ID = os.environ["DEVIN_ORG_ID"]
SESSION_ID = os.environ["SESSION_ID"]
BASE = "https://api.devin.ai/v3"
HEADERS = {"Authorization": f"Bearer {API_KEY}"}

# List attachments
attachments = requests.get(
    f"{BASE}/organizations/{ORG_ID}/sessions/{SESSION_ID}/attachments",
    headers=HEADERS
).json()["items"]

# Download each attachment
for att in attachments:
    print(f"Downloading {att['name']}...")
    content = requests.get(att["url"]).content
    with open(att["name"], "wb") as f:
        f.write(content)
    print(f"  Saved {att['name']} ({len(content)} bytes)")

​
Knowledge 和 playbook 管理

管理 Devin 在多个会话中使用的上下文和指示。

​

​
完整的 Python 示例

import os
import requests

API_KEY = os.environ["DEVIN_API_KEY"]

}

# 创建 Knowledge 笔记
note = requests.post(
    f"{BASE}/organizations/{ORG_ID}/knowledge/notes",
    headers=HEADERS,
    json={
        "name": "Coding standards",
        "trigger": "When writing code in any repository",
        "body": "Use TypeScript strict mode. Follow existing code style."

​
设置自动化会话计划

创建按计划重复运行的会话。

​
创建计划

curl -X POST "https://api.devin.ai/v3/organizations/$DEVIN_ORG_ID/schedules" \
  -H "Authorization: Bearer $DEVIN_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "prompt": "Run the test suite and report any failures",
    "cron_schedule": "0 9 * * 1-5",
    "timezone": "America/New_York"
  }'
这会创建一个计划，于美国东部时间每个工作日上午 9 点运行。

​
列出计划

curl "https://api.devin.ai/v3/organizations/$DEVIN_ORG_ID/schedules" \
  -H "Authorization: Bearer $DEVIN_API_KEY"

​
更新计划

curl -X PATCH "https://api.devin.ai/v3/organizations/$DEVIN_ORG_ID/schedules/$SCHEDULE_ID" \
  -H "Authorization: Bearer $DEVIN_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "cron_schedule": "0 8 * * 1-5",
    "is_enabled": true
  }'

​
删除计划

curl -X DELETE "https://api.devin.ai/v3/organizations/$DEVIN_ORG_ID/schedules/$SCHEDULE_ID" \
  -H "Authorization: Bearer $DEVIN_API_KEY"

​
完整的 Python 示例

import os
import requests

API_KEY = os.environ["DEVIN_API_KEY"]
ORG_ID = os.environ["DEVIN_ORG_ID"]
BASE = "https://api.devin.ai/v3"
HEADERS = {
    "Authorization": f"Bearer {API_KEY}",
    "Content-Type": "application/json"
}

# 创建每日健康检查计划
schedule = requests.post(
    f"{BASE}/organizations/{ORG_ID}/schedules",
    headers=HEADERS,
    json={
        "prompt": "Run the test suite and report any failures",
        "cron_schedule": "0 9 * * 1-5",
        "timezone": "America/New_York"
    }
).json()
print(f"Created schedule: {schedule['schedule_id']}")

# 列出所有计划
schedules = requests.get(
    f"{BASE}/organizations/{ORG_ID}/schedules",
    headers={"Authorization": f"Bearer {API_KEY}"}
).json()["items"]

for s in schedules:
    status = "enabled" if s.get("is_enabled") else "disabled"
    print(f"  {s['schedule_id']}: {s['cron_schedule']} ({status})")

​
错误处理

以上所有示例在生产环境中都应包含错误处理。下面提供一种可复用的写法： 
import requests

def api_request(method, url, headers, **kwargs):
    """发起带有标准错误处理的 API 请求。"""
    response = requests.request(method, url, headers=headers, **kwargs)
    try:
        response.raise_for_status()
        return response.json()
    except requests.exceptions.HTTPError as e:
        status = e.response.status_code
        if status == 401:
            raise Exception("Invalid or expired API key")
        elif status == 403:
            raise Exception("Service user lacks required permission")
        elif status == 404:
            raise Exception("Resource not found")
        elif status == 429:
            raise Exception("Rate limit exceeded — wait and retry")
        else:
            raise Exception(f"API error {status}: {e.response.text}")
