Source capping settings allow you to manage how much traffic - such as Impressions, Ad Requests, and Ad Opportunities - a specific supply source receives.
Timezone Notice: All daily limits are calculated based on the EST (GMT-5) timezone.
Ad Requests per second and Automatic Caps
The Ad Requests per second limit controls the number of ad requests sent to a source per second.
Whenever you set an Ad Requests per second value, the system automatically calculates and applies both the Hourly and Daily Ad Request Caps. This ensures your sources are always protected from oversupply.
Example:
If Ad Requests per second = 1,000
Hourly Cap = 3,600,000 requests
Daily Cap = 86,400,000 requests
These caps are recalculated automatically each time you update your Ad Requests per second cap. While they are not visible in the UI yet, they are applied in the background to safeguard traffic flow and keep source delivery balanced.
IMPORTANT: Aligning Ad Requests per second and Daily/Hourly Limits
If you use both Ad Requests per second and Daily or Hourly limits, please make sure they are aligned. If your Daily/Hourly cap is higher than the cap calculated from Ad Requests per second, the system will apply both limits, and filtering will start once either one is reached.
Example:
If Ad Requests per second = 1,000
Hourly Cap = 360,000 requests
Daily Cap = 8,640,000 requests
But if your Hourly Limit = 500,000 ad requests, the system will still enforce the backend Hourly Cap of 360,000 requests first.
Volume Limits
You can set limits for the following metrics:
- Ad Requests
- Ad Opportunities
- Impressions
Each of these can be capped on:
- An hourly basis
- A daily basis (defined as a rolling 24-hour period)
