🚀 Getting started

Install the app from the landing page, authorize with OAuth, and the two actions will appear in your workflow builder automatically.

⚡ Run Custom Code

Execute JavaScript code inside your HubSpot workflows. Map contact properties as input variables and return values for downstream branches.

Input fields

  • Input variables (JSON) — A JSON object mapping variable names to HubSpot property tokens: {"email": "{{ contact.email }}"}. These become available as event.inputFields inside your code.
  • JavaScript Code — Define exports.main exactly like HubSpot's native Custom Code action. Access variables via event.inputFields and return outputs via callback.

Example

// Input variables (JSON): { "email": "{{ contact.email }}", "name": "{{ contact.firstname }}" } // JavaScript Code: exports.main = async (event, callback) => { const email = event.inputFields['email'] || ''; const domain = email.split('@')[1] || ''; const isPremium = String(domain === 'corp.com'); callback({ outputFields: { out1: domain, out2: isPremium } }); };

Available modules

Your code can require() the following modules:

  • axios — HTTP requests
  • crypto, url, querystring, util, path, buffer — Node.js built-ins

Outputs

Up to 10 outputs (out1…out10) plus an error field (empty string on success). Use them in workflow branches.

Limits

Limit Value
Timeout 15 seconds
Memory 128 MB
Max output size 65,000 characters
Allowed modules axios + Node.js built-ins (no fs, child_process, net)

🔗 Send Webhook

Send HTTP requests to any URL from your workflows. Perfect for integrating with Zapier, Make, n8n, or any API.

Input fields

  • URL — The endpoint to send the request to.
  • Method — HTTP method (GET, POST, PUT, PATCH, DELETE).
  • Headers (JSON) — Optional HTTP headers as a JSON object.
  • Body — Request body (for POST/PUT/PATCH). Supports HubSpot property tokens.

Example

// URL: https://hooks.zapier.com/hooks/catch/123456/abc123 // Method: POST // Headers: { "Content-Type": "application/json" } // Body: { "email": "{{ contact.email }}", "name": "{{ contact.firstname }}" }

Outputs

  • statusCode — HTTP response status code
  • responseBody — Response body as string
  • error — Error message (empty on success)

🔀 Using outputs in branches

Method 1 — Direct branch: Use "One action output (value equals)" right after the action.
[Run Custom Code] → output: isPremium = "true" ↓ [Branch: isPremium] ├── "true" → [Send VIP email] └── "false" → [Send standard email]
Method 2 — Property + If/Then: Save the output to a contact property first, then use it in an If/Then branch for complex AND/OR logic.
[Run Custom Code] → output: domain = "corp.com" ↓ [Set property: company_domain = domain] ↓ [If/Then: company_domain contains "corp.com" AND score > 80]
