  title: LoyaltyLion Activities Redemptions 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.
