Track subscription payments and revenue attribution by connecting your Paddle account

Step 1: Get Paddle API Credentials

  1. Log in to your Paddle Vendor Dashboard
  2. Go to Developer Tools → Authentication
  3. Copy your Vendor ID
  4. Generate or copy your Vendor Auth Code
  5. Alternatively, create an API Key for more secure access

💡 Tip: API Keys are recommended over Vendor Auth Codes for production environments.

  1. Go to Settings → API Integrations
  2. Select ROI Platforms from the dropdown
  3. Choose Paddle
  4. Enter your Vendor ID
  5. Enter your Vendor Auth Code or API Key

Step 3: Track UTM Parameters

To attribute Paddle transactions to specific email campaigns, use the passthrough parameter:

passthrough: JSON.stringify({ utm_source: 'newsletter', utm_medium: 'email', utm_campaign: 'spring-sale' })

Email Calculator will automatically extract UTM parameters from the passthrough field to attribute sales to campaigns.
