Go to the Publisher listing page, click the Edit icon next to any publisher, navigate to the Leadtype Settings tab, and select the lead type you want to configure.

Scroll down below the Profit Margin and Publisher Payout fields to find the Duplicate Check section. Here you will see five duplicate filter options available.

Check the fields you want to use for duplicate detection:

• Duplicate on Email — blocks leads with the same email address
• Duplicate on Phone — blocks leads with the same phone number
• Duplicate on Universal Lead ID — blocks leads with the same Universal Lead ID
• Duplicate on xxTrustedFormCertUrl — blocks leads with the same Trusted Form certificate URL
• Duplicate on IP Address — blocks leads submitted from the same IP address

For each selected field, enter the number of days the system should check for duplicates. For example:

• Setting Phone for 10 days — blocks any lead with the same phone number submitted within the last 10 days
• Setting xxTrustedFormCertUrl for 50 days — blocks the same Trusted Form certificate URL from being used again within 50 days
• Setting 0 days — means no duplicate check is applied for that field

Once all duplicate check fields and day limits are configured, click Save. The system will now automatically block any duplicate leads based on your selected fields and time period — ensuring only fresh and unique leads are accepted from this publisher.
