Unique Project Identifier

Protect your surveys from ghost completes and redirect manipulation.

Unique Project Identifier adds an additional layer of redirect security by attaching a unique identifier to your project's complete URL. This ensures only participants completing the correct survey path can be marked as complete, helping to eliminate survey jumpers and fraudulent redirects.

Key Benefits

• Redirect Security: Prevents ghost completes and URL tampering

• End-to-End Control: Verifies completion authenticity between dtect and the survey

• Easy Monitoring: Track redirect failures in real time on the Progress tab

How It Works

Unlike other security checks, UPI is evaluated after survey completion, when participants are redirected from the survey platform back to dtect.

If the participant returns with a missing or incorrect Unique Project Identifier, dtect will security terminate the participant and redirect them to the supplier's Security Terminate URL.

✅ Valid UPI → participant is processed normally
❌ Missing or incorrect UPI → participant is terminated as a security terminate

Complete URL Format

When UPI is enabled, your complete redirect will include a upi parameter:

🔗 Without UPI:
https://participation.dtect.io/redirect?status=complete&id={dtect.id}

🔐 With UPI:
https://participation.dtect.io/redirect?status=complete&id={dtect.id}&upi={unique_id}

Enabling Uniquer Project Identifier

Uniquer Project Identifier must be enabled during project creation. This setting cannot be changed once a project is live.

When enabled, the dtect portal will visually indicate Uniquer Project Identifier activation:

📍Project with UPI enabled:

📍Project without UPI:

Monitoring Redirect Security

Unique Project Identifier-related failures are visible in real time on the Progress tab, making it easy to monitor potential redirect fraud.

For detailed insights, export your project data. Look for these fields:

• dtect Status Description: Incorrect Unique Project Identifier

• dtect Status: complete

• survey Status: security_terminate

Best Practices

• Enable Unique Project Identifier by default but especially for high-value studies or when working with multiple suppliers

• Confirm the correct redirect URL format is implemented in your survey tool

• Monitor Progress tab for trends in failed Unique Project Identifiers to identify redirect tampering or incorrect setup
