Conversion Rejection Threshold
What it detects
When a sub ID accumulates a high proportion of rejected conversions — due to duplicate IPs, VPN usage, device fraud, or other active rules — it signals that the source is generating low-quality or fraudulent traffic. The Conversion Rejection Threshold filter blocks further clicks from that sub ID once the rejection rate exceeds your configured limit.
How it works
Integr8 calculates the rejection rate for each sub ID over the lookback window using this formula:
rejection_rate = (total_rejected / total_conversions) * 100When the rejection rate exceeds max_rejection_percentage and the minimum conversion count is met, Integr8 blocks clicks from that sub ID. This prevents additional fraudulent traffic from reaching the advertiser while the source is under review.
Configuration
Navigate to Fraud Prevention > Conversion Fraud > Conversion Rejection Threshold to configure this filter.
| Parameter | Default | Range | Description |
|---|---|---|---|
max_rejection_percentage | 70% | 1–100% | Maximum rejection rate before sub ID is blocked |
min_conversions | 20 | 1–10,000 | Minimum conversions before filter evaluates |
lookback_window | 7 days | 1–30 days | Time window for rejection rate calculation |
What happens when triggered
When the rejection threshold is exceeded:
- Clicks from the offending sub ID are blocked with
fraud_reason: rejection_threshold. - The block applies at the sub ID level — other sub IDs from the same publisher continue to operate normally.
- The block remains in effect until the rejection rate drops below the threshold within a new lookback window, or you manually clear it.
Review blocked sub IDs in Reports > Click Reports filtered by fraud_reason: rejection_threshold.
Setting max_rejection_percentage too low (under 20%) may block legitimate sub IDs during campaign ramp-up when conversion volumes are small. Use min_conversions to prevent premature blocking.
