Approval rules are policy gates configured on your campaigns. When a rule fires on a referral, the reward is held and the referral surfaces in either [Pending Rewards](/knowledge-v2/customers/pending-rewards) or [Fraud Review](/knowledge-v2/customers/fraud-review), depending on the rule's category. Each rule maps to one of five **categories**, colour-coded in the **Reason** column on Pending Rewards. ## Categories | Category | Colour | When it fires | Where it shows | | --------------- | -------- | --------------------------------------------------------------------------------------------------------------------------- | --------------- | | **Fraud score** | Red | Customer fraud score crossed the configured threshold. | Fraud Review | | **Limits** | Amber | A volume or velocity cap fired (referrals or referees per period, value caps, rapid referrals). | Fraud Review | | **Eligibility** | Sky blue | An eligibility rule fired (referrer must be a customer, blocked customer, blocked referrer, email-pattern, referring-site). | Fraud Review | | **Reward** | Violet | The reward itself is configured to require approval or has a delay window. | Pending Rewards | | **Other** | Grey | Reason couldn't be categorised. Open the customer profile to investigate. | Either | ## Rule Catalogue ### Fraud score | Rule | What it checks | | ------------------------------ | ----------------------------------------------------------------- | | Referrer fraud-score threshold | The referrer's fraud score is above your campaign threshold. | | Referee fraud-score threshold | The referee's fraud score is above your campaign threshold. | | Action fraud-score threshold | The Incentive-For-Action (IFA) fraud score crossed its threshold. | ### Limits | Rule | What it checks | | --------------------------------------- | ----------------------------------------------------------------------------- | | Daily referral cap (per referrer) | Referrer has made more referrals than allowed in 24 hours. | | Monthly referral cap (per referrer) | … in a month. | | Yearly referral cap (per referrer) | … in a year. | | Daily new-referee cap (per referrer) | Referrer has brought in more referees than allowed in 24 hours. | | Monthly new-referee cap (per referrer) | … in a month. | | Yearly new-referee cap (per referrer) | … in a year. | | Yearly reward-value cap (GBP) | Total reward value to this referrer this year has crossed your GBP cap. | | Yearly reward-value cap (EUR) | … EUR cap. | | Yearly reward-value cap (USD) | … USD cap. | | Burst referrals from same referrer + IP | This referrer sent multiple referrals from the same IP within a short window. | | Burst referrals across this brand | Multiple rapid referrals were sent across your account. | | Burst referrals from one IP | A single IP sent multiple referrals rapidly, regardless of referrer. | ### Eligibility | Rule | What it checks | | ------------------------------------- | ----------------------------------------------------------------------------------------------------- | | Referrer must be an existing customer | Referrer must be an existing paying customer. | | Referrer email allow / block list | Referrer email matches a configured pattern (allow / deny). | | Referee landing-site allow list | The site the referee arrived from doesn't match the allowlist. | | Customer block list | The customer (referrer or referee) is [blocked](/knowledge-v2/customers/common-tasks/block-customer). | | Referrer block list | The referrer is blocked. | ### Reward | Rule | What it does | | ------------------------ | -------------------------------------------------------------------------------------------------- | | Reward requires approval | Reward is configured to need manual approval. | | Reward has delay period | Reward has a configured delay before auto-approval. The pending row shows when it'll auto-approve. | ## Cross-Rule Behaviour Some rules overlap with fraud signals (for example, blocked-customer eligibility rules also count as a "Known bad" fraud bucket). Where this happens, the **Assessment** cell on [Fraud Review](/knowledge-v2/customers/fraud-review) shows the bucket headline; the **Reason** cell on [Pending Rewards](/knowledge-v2/customers/pending-rewards) shows the rule category. ## Where to Change a Rule Approval rules are configured per campaign. From [Top approval rules](/knowledge-v2/customers/fraud-review#top-approval-rules) on Fraud Review, click the rule headline to jump to the underlying campaign settings. ## See Also The queue where Reward-category rules surface.
