  title: LoyaltyLion API
  description: >-
    The LoyaltyLion v2 REST API powers an e-commerce loyalty and rewards program.
    It is split into an Admin API - for moving data in and out of LoyaltyLion, such
    as retrieving customers and transactions, tracking orders, and adjusting points
    - and a Headless API for building custom shopper-facing loyalty experiences in
    web, mobile, and POS applications. Requests authenticate with a Program API key
    passed as a Bearer token in the Authorization header (with scoped access such as
    read_customers), or the deprecated token/secret pair over HTTP Basic auth
    (supported until 2027-01-10). Customers are addressed by the merchant_id you use
    in your own platform. All endpoints share a rate limit of 20 requests per second
    unless otherwise stated. This document grounds the core Customers, Activities,
    Points, Rewards, and Redemptions resources; some verbs are modeled from the
    documented resource index and should be verified against the live reference.
