Notifications alert you when workflows complete, fail, or detect data changes. You can receive them via email, webhooks, or WebSockets. The SDK handles channel management automatically.
For event types and channel details, see Notifications.

​
Quick Start

import { KadoaClient } from "@kadoa/node-sdk";

const client = new KadoaClient({ apiKey: "your-api-key" });

await client.notification.setupForWorkflow({
  workflowId: "your-workflow-id",
  events: ["workflow_data_change"],
  channels: {
    WEBHOOK: {
      name: "my-webhook",
      webhookUrl: "https://your-server.com/webhook",
      httpMethod: "POST",
    },
  },
});
The SDK reuses existing channels with the same name. Running setup multiple times won’t create duplicates.

​
Channel Types

​
Email

// Use account email
await client.notification.setupForWorkflow({
  workflowId: workflowId,
  events: ["workflow_finished", "workflow_failed"],
  channels: { EMAIL: true },
});

// Or specify recipients
await client.notification.setupForWorkflow({
  workflowId: workflowId,
  events: ["workflow_finished"],
  channels: {
    EMAIL: {
      name: "team-notifications",
      recipients: ["team@example.com"],
    },
  },
});

​
Slack

await client.notification.setupForWorkflow({
  workflowId: workflowId,
  events: ["workflow_failed"],
  channels: {
    SLACK: {
      name: "team-notifications",
      slackChannelId: "C1234567890",
      slackChannelName: "alerts",
      webhookUrl: "https://hooks.slack.com/services/YOUR/WEBHOOK",
    },
  },
});

​
Webhook

await client.notification.setupForWorkflow({
  workflowId: workflowId,
  events: ["workflow_data_change", "workflow_finished"],
  channels: {
    WEBHOOK: {
      name: "api-integration",
      webhookUrl: "https://api.example.com/webhooks/kadoa",
      httpMethod: "POST",
    },
  },
});

​
WebSocket

Receive events in real-time 
const client = new KadoaClient({ apiKey });
const realtime = await client.connectRealtime();

// Subscribe to all events
realtime.onEvent((event) => {
  console.log("Event received:", event.eventType, event.message);
});

// Filter events by type
realtime.onEvent((event) => {
  if (event.eventType === "workflow_finished") {
    console.log("Workflow completed:", event.message);
  }
});

// Handle errors
realtime.onError((error) => {
  console.error("WebSocket error:", error);
});

realtime.close();

​
Subscribe to All Events

await client.notification.setupForWorkflow({
  workflowId: workflowId,
  events: "all",
  channels: { EMAIL: true },
});

​
Reusing Channels

Reference existing channels by ID 
// List channels
const channels = await client.notification.channels.listChannels({});
const webhookChannel = channels.find(c => c.name === "my-webhook");

await client.notification.setupForWorkflow({
  workflowId: newWorkflowId,
  events: ["workflow_data_change"],
  channels: {
    WEBHOOK: { channelId: webhookChannel.id },
  },
});

​
Setup Notifications via API

​
Step 1: Create Notification Channels

First, create the channels you want to use for notifications. See Emails, Webhooks and WebSockets for channel creation examples.

​
Step 2: Subscribe to Events

Subscribe to events by sending a POST request to /v5/notifications/settings.

​
Workspace-Level Subscription

Apply notifications to all workflows: 
// POST /v5/notifications/settings
{
  "eventType": "workflow_finished",
  "eventConfiguration": {},
  "enabled": true,
  "channelIds": ["<channel-id>"]
}

​
Workflow-Level Subscription

Apply notifications to a specific workflow: 
// POST /v5/notifications/settings
{
  "workflowId": "<your-workflow-id>",
  "eventType": "workflow_data_change",
  "eventConfiguration": {},
  "enabled": true,
  "channelIds": ["<channel-id>"]
}

​
Step 3: Update Existing Settings

To add more channels to existing settings, use a PUT request: 
// PUT /v5/notifications/settings/<settings-id>
{
  "channelIds": ["existing-channel-id", "new-channel-id"]
}
For payload formats, see Emails, Webhooks, and WebSockets.
