Authorizations

Authorization

string

header

required

每个请求都通过 API Key 认证：Authorization: Bearer {API_KEY}。应用接口使用应用 API Key，知识库接口使用知识库 API Key（快速开始）。

API Key 应保存在服务端，切勿嵌入客户端代码。缺失或无效的 Key 会返回 HTTP 401（unauthorized）。

Path Parameters

workflow_run_id

string<uuid>

required

要恢复事件流的工作流运行 ID，来自执行工作流的响应或流式事件。

Query Parameters

user

string

required

终端用户标识，由你的应用定义，需在应用内唯一。必须与发起该运行的 user 一致。参见终端用户身份。

include_state_snapshot

boolean

default:false

为 true 时，从持久化状态快照重放，在流式发送新事件前附带已执行节点的状态摘要。

continue_on_pause

boolean

default:false

设为 true 时，流会在多次 workflow_paused 事件之间保持打开（适用于工作流包含多个连续人工介入节点的场景）。默认在首次暂停时关闭流。

Response

Server-Sent Events 流。流以保活用的 event: ping 帧（不带 data:）开头，之后约每 10 秒到达一次；其余事件以 data: {JSON}\n\n 形式送达。事件载荷结构与原始流式响应一致。

已恢复工作流运行的事件 SSE 流，格式与执行工作流（Workflow 应用）或发送对话消息（Chatflow 应用）相同。当恢复部分运行设置 reasoning_format: separated 的 LLM 节点时，本流还会携带 reasoning_chunk 事件。
