# n8n 集成

> 通过 n8n-nodes-chainstream 社区节点，将 ChainStream 连接到 n8n 工作流自动化。

`n8n-nodes-chainstream` 是一个社区节点，可将 ChainStream 的链上数据直接引入 [n8n](https://n8n.io) 工作流自动化。查询代币元数据、监控交易、跟踪钱包活动——无需编写代码。

<Info>
  **包名：** `n8n-nodes-chainstream` v0.0.92 | **已发布版本：** 63 | 已在 [n8n Creator Portal](https://n8n.io) 上架
</Info>

## 安装

1. 打开你的 n8n 实例。
2. 前往 **Settings > Community Nodes**。
3. 点击 **Install** 并输入：

```
n8n-nodes-chainstream
```

4. 确认安装，如有提示则重启 n8n。

## 认证

该节点通过 ChainStream Dashboard 签发的 API 凭证进行认证。

1. 在 ChainStream Dashboard 中，导航至 **Settings > API Keys**。
2. 创建新的密钥对。你将获得：
   * **API Client ID**
   * **API Client Secret**
3. 在 n8n 中，前往 **Credentials > New Credential > ChainStream API**。
4. 输入 Client ID 和 Client Secret，然后保存。

```json theme={null}
{
  "credentials": {
    "chainstreamApi": {
      "clientId": "cs_live_xxxxxxxxxxxxxxxx",
      "clientSecret": "your_client_secret_here"
    }
  }
}
```
