Global limits

The global limits constraint sets a maximum total number of redemptions for a promotion across all participants. Once the limit is reached, the promotion is automatically deactivated and no longer appears in any participant's list -- regardless of how much time remains in the validity period.

How it works​

The system maintains a counter of the total number of times the promotion has been successfully redeemed. When the counter reaches the configured limit, the promotion is closed for everyone. This happens automatically, with no manual intervention required.

Setting the global limit to 0 disables the constraint -- the promotion can be redeemed an unlimited number of times until the validity period ends.

When to use it​

Global limits are the primary tool for running quantity-capped campaigns -- promotions tied to a finite budget or a limited stock of rewards.

Common scenarios:

  • Budget-capped campaigns. If you have allocated a specific budget for a promotion (for example, €500 in extra cashback), you can calculate the maximum number of redemptions that budget can absorb and set that as the global limit. The promotion closes automatically when the budget is consumed.
  • First-come, first-served offers. Setting a low global limit creates scarcity, which can drive urgency and early engagement among participants who learn about the promotion.
  • Prize promotions. If the promotional benefit is a voucher or gift with limited availability, the global limit ensures you never commit to more rewards than you have available.

Interaction with other constraints​

Global limits and user limits are independent. Both can be active simultaneously. The promotion closes for a specific participant when they hit their personal user limit, and closes for everyone when the global limit is reached -- whichever comes first.

No reservation mechanism

The global limit is checked and decremented at the moment a transaction is successfully completed. There is no reservation at opt-in time. In high-traffic scenarios with a very low global limit, two participants could opt in simultaneously and both complete transactions before the counter has been updated, resulting in a slight overshoot. For promotions where the limit is in the hundreds or thousands, this is unlikely to be an issue in practice.
