Connect Paddle to Email Calculator
Track subscription payments and revenue attribution by connecting your Paddle account
Step 1: Get Paddle API Credentials
- Log in to your Paddle Vendor Dashboard
- Go to Developer Tools → Authentication
- Copy your Vendor ID
- Generate or copy your Vendor Auth Code
- Alternatively, create an API Key for more secure access
💡 Tip: API Keys are recommended over Vendor Auth Codes for production environments.
Step 2: Add Paddle Integration in Email Calculator
- Go to Settings → API Integrations
- Select ROI Platforms from the dropdown
- Choose Paddle
- Enter your Vendor ID

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.
