Workflow Helpers Skill

This skill provides advanced workflow manipulation capabilities for n8n.

When to Use

• Getting webhook URLs from workflows
• Duplicating workflows (with credential stripping for sharing)
• Adding nodes to existing workflows
• Creating workflows with specific triggers
• Getting workflow statistics

Core Methods

Get Webhook URL

Extract the webhook URL from a workflow:

const result = await workflowHelper.getWebhookUrl(workflowId)

Result:

interface WebhookUrlResult {
  success: boolean
  url?: string      // Full webhook URL
  path?: string     // Webhook path
  method?: string   // HTTP method (GET, POST, etc.)
  error?: string
}

Example:

const webhook = await workflowHelper.getWebhookUrl('123')

if (webhook.success) {
  console.log(`URL: ${webhook.url}`)
  // https://n8n.example.com/webhook/my-path
  console.log(`Method: ${webhook.method}`)
  // POST
}

Duplicate Workflow

Create a copy of a workflow, optionally stripping credentials:

const result = await workflowHelper.duplicate(
  sourceId,         // Source workflow ID
  newName,          // Name for the copy
  stripCredentials  // Remove credentials (default: true)
)

Result:

interface DuplicateResult {
  success: boolean
  workflowId?: string   // New workflow ID
  name?: string
  error?: string
}

Example:

// Create shareable copy (no credentials)
const copy = await workflowHelper.duplicate('123', 'My Workflow - Copy', true)

if (copy.success) {
  console.log(`Created workflow: ${copy.workflowId}`)
}

// Create working copy (keep credentials)
const workingCopy = await workflowHelper.duplicate('123', 'My Workflow - Dev', false)

Add Node to Workflow

Add a new node to an existing workflow:

const result = await workflowHelper.addNode(workflowId, {
  name: 'My Node',
  type: 'n8n-nodes-base.httpRequest',
  position: [450, 300],
  parameters: {
    url: 'https://api.example.com',
    method: 'GET'
  },
  credentials: {
    httpHeaderAuth: { id: 'cred-id', name: 'My Auth' }
  }
})
