Using Multiple Actions​

Sequential Actions​

    ↓
Action 1: Add to Google Sheets
    ↓
Action 2: Send Slack notification
    ↓
Action 3: Create HubSpot contact

Conditional Paths​

Use Paths for conditional logic:

Trigger: OneTap Webhook
    ↓
Path A: If event = user_registered
    → Action: Welcome email
    ↓
Path B: If event = user_logged_in
    → Action: Update last login

Filtering Events​

Filter by Event Type​

Add a Filter step:

Condition: event (Text) Exactly matches user_registered

This only runs for new registrations, not logins.

Filter by Domain​

Condition: user > email (Text) Contains @company.com

This only runs for specific email domains.

Troubleshooting​

Webhook Not Received​

  1. Verify webhook URL is correct
  2. Check webhook is enabled in OneTap Login
  3. Use "Send Test Webhook" to verify
  4. Check Zapier's task history

Data Not Mapping Correctly​

  1. Review sample data in Zapier
  2. Check field names match
  3. Use Formatter for data transformation
  4. Test with fresh trigger data

Zap Turning Off​

  1. Check for errors in Zap history
  2. Verify connected accounts still valid
  3. Ensure you're within Zapier plan limits
  4. Check OneTap webhook is still enabled

Delayed Processing​

  1. Zapier free tier may have delays
  2. Upgrade for faster processing
  3. Check Zapier system status
