title: Voucherify Loyalty v2 API
version: 2.0.0
description: >-
Complete OpenAPI specification for the Voucherify Loyalty v2 API.
All endpoints require the LOYALTY_V2 feature flag.
Combined from per-domain specs: programs.yaml, members.yaml,
program-operations.yaml, card-definitions.yaml, earning-rules.yaml,
tier-structures.yaml, benefits.yaml, rewards.yaml, examine.yaml

Loyalty program CRUD, lifecycle management, program-scoped resource
assignments (card definitions, earning rules, rewards, tier structures),
member management (create, list, get, activate, deactivate, delete),
membership retrieval (member + program + cards with tier progress, by
customer ID, customer source ID, or member ID), card operations (points
adjustment, pending points, expiring points, transactions), reward
purchases, and activity history.
- name: Card Definitions
description: >-
CRUD operations, lifecycle management, and activity history for card
definitions. Card definitions describe the configuration for loyalty
cards, including code generation, points expiration, earning/spending
limits, pending points, refunds, and balance settings.
- name: Earning Rules
description: >-
Manage earning rules that define how customers earn points or receive
incentives based on triggers (events, segments, custom events). Includes
CRUD, lifecycle, and activity history.
- name: Tier Structures
description: >-
CRUD operations, lifecycle management, and activity history for tier
structures. Includes nested tier definitions (create, list, update,
delete) within tier structures. Tier structures define the tiering model
for loyalty programs — how members qualify for and move between tiers.
- name: Benefits
description: >-
Manage benefit definitions (fixed points, proportional points, material,
digital). Includes CRUD, lifecycle transitions, and activity history.
- name: Rewards
description: >-
CRUD, lifecycle operations, and activity history for reward definitions.
Rewards can be material (product/SKU) or digital (discount coupons, gift
vouchers).
- name: Examine
description: >-
Evaluation endpoints that estimate earning opportunities and reward
availability for a customer across their loyalty program memberships,
without side effects.
