Each step defines key and optional settings that specify how a rule works and its scope. ### Details (required) This step defines the rule's identification and lifecycle management. * **Name**: The unique name of the earning rule, used for management and reporting. * Earning rule type: Defines what customers need to do to earn points. There are four main earning rule types: * Order has been paid * Custom event * Entered segment * Tier events * **Time frame** (optional): Defines the period when the rule is active and customers can earn points through this rule. * **Inheritance**: If a time frame is not defined, the rule inherits the settings from the parent loyalty campaign. * **Time frame options**: * Start date and time * End date and time (expiration) * Valid in this timeframe only (recurring) * Valid on particular days only ### Points (required) This step defines the reward value, timing, and expiration rules for the points earned. * **Point value**: Determines how many loyalty points the customer will receive. * It can be a **fixed** value (for example, 50 points) or a **dynamic value** calculated using the **points formula builder**. * It can be a **proportional** value (for example, 10 points for every \$10 spent) that scales with a selected condition. **Proportional** values are unavailable in **Tier events** rules. * **Pending points**: You can set a delay time before customers can actually use the earned points. * You can set a specific pending period in days. * Points are added to the customer's account immediately but remain in a pending state. Once the set number of days has passed, the points are automatically made available to the customer. * **Expiration rules**: Configuration defining when the points acquired through this specific earning rule will expire. If an earning rule doesn't have its own expiration rule, the campaign-level point expiration will be used instead. ### Validation rules (optional) [Validation rules](/optimize/validation-rules-reference) are additional conditions that the customer needs to meet to gain points with the earning rule. Validation rules in earning rules Validation rules can additionally define the following conditions: * Cart structure and volume, like minimum order value. * Customer data, like only for customers in a given country * Qualified customer segments, like only for the "Premium customers" segment ### Metadata (optional) The **Metadata** step allows you to attach custom attributes to the earning rule by defining key/value pairs. Use metadata for internal tracking, organization, or in more advanced logic. ## Earning rules by types Learn how points are calculated and awarded for each rule type, focusing on **proportional earning** and required **metadata schema**. Earning rules based on metadata must have a **Number** type and be defined in the **Metadata Schema**. ### Order has been paid **Order has been paid** rule adds points to the customer's loyalty card when a new order changes its status to **PAID**. There are two earning methods for the **Order has been paid** earning rule. * **Fixed**: Awards a fixed number of points for paying for an order. * **Proportional**, awards a defined number of points (*X*) for every predefined value (*Y*) in the selected metric, like amount spent. The following **Proportional** methods are available: * **Pre-discount order amount**: Awards X points for every \$Y spent, excluding discounts (order total amount counted *before* discounts were applied). * **Total order amount**: Awards X points for every \$Y spent including discounts (order total amount counted *after* discounts were applied). * **Pre-discount amount spent on items**: Awards X points for every \$Y spent on specific items or collections, excluding discounts. * **Amount spent on items**: Awards X points for every \$Y spent on specific items or collections, including discounts. * **Quantity of items in the cart**: Awards X points for every Y items, excluding free items. * **Order metadata**: Awards X points proportionally to the value of a metadata attribute defined in the **Order** schema. * **Customer metadata**: Awards X points proportionally to the value of a metadata attribute defined in the **Customer** schema. When selecting multiple products or collections for proportional earning, if the same item belongs to multiple selected collections, points will be calculated based on eligible items only once. ### Custom event Prerequisite A custom event must be first defined in **Project Settings** > **Event Schema**. Sending custom events to Voucherify requires developer implementation and use of the [POST Track custom event](/api-reference/events/track-custom-event) endpoint. Custom events are actions taken by your customers that are tracked in your application or website and passed to Voucherify using the API. When a custom event earning rule is used with a **Validation rule**, the moment the event is received, Voucherify checks if the customer linked to the event matches the conditions defined in the **Validation rule**, like segment rules, customer metadata, or custom event metadata. There are two earning methods for **Custom event** earning rule: * **Fixed**: Awards a fixed number of points when the **Custom event** occurs. * **Proportional**: Awards a defined number of points (*X*) for every predefined value (*Y*) in the selected metric. The following **Proportional** methods are available: * **Customer metadata**: Value comes from a metadata attribute defined in the **Customer schema**. * **Custom event metadata**: Value comes from a metadata attribute defined as a property of the chosen event in the **Event schema**. ### Entered segment Segments group customers based on defined filter criteria. The **Entered segment** earning rule awards points only when the customer meets all segment conditions. The **Entered segment** earning rule adds points to the customers who enter the selected segment when the earning rule is active. Customers who have already entered the segment won't receive points. There are two earning methods for the **Entered segment** earning rule: * **Fixed**: Awards a fixed number of points when the customer enters the segment. * **Proportional**: Awards a defined number of points (*X*) for every predefined value (*Y*) in the **Customer** metadata. ### Tier events Prerequisite The **Tier events** earning rule uses the loyalty tiers created in the **Tiers (optional)** step in the loyalty campaign builder. **Loyalty tiers** are different membership levels in a loyalty program, defined by a minimum and, optionally, maximum point range. Points are added when a specific tier-related change occurs, provided that all related conditions are met. There are the following **Tier events**: * **Joined tier structure**: Customer earns points when they join the tier structure for the first time. * **Left tier structure**: Customer earns points when they leave the tier structure. * **Tier upgraded**: Customer earns points when they reach a higher loyalty tier. * **Tier downgraded**: Customer earns points when they fall to a lower loyalty tier. * **Tier prolonged**: Customer earns points when their current tier level is extended. By default, the **Tier events** apply to **Any** loyalty tier. Optionally, you can define a **Specific tier** that will trigger the **Tier event**. There are two earning methods for the **Tier events** earning rule: * **Fixed**: Awards a fixed number of points when the tier event occurs. * **Proportional**: Awards a defined number of points (*X*) for every predefined value (*Y*) in the **Customer** metadata.
