Loyalty Interchange Protocol review
A flexible, API-first loyalty stack for teams prepared to self-host and implement it.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Loyalty Interchange Protocol is an Apache-2.0 open-source loyalty platform and vendor-neutral transaction protocol for restaurant, QSR, coffee, convenience, and franchise technology teams. It combines a loyalty engine with transaction and checkout APIs, customer profiles, campaigns, attribution analytics, a guest wallet, restaurant adapters, an Admin dashboard, and developer tooling. It is aimed at technical teams connecting loyalty with ordering, payments, refunds, locations, and existing identity systems.
Its ecosystem is built for integration rather than isolation. The platform includes a Square Orders adapter with webhook signature verification, integrations for Clerk, Auth0, OIDC providers, SQLite, PostgreSQL, and Stripe, plus a TypeScript SDK and generated OpenAPI client. The published capabilities cover member enrollment, balances, ledger history, pre-checkout order evaluation, post-payment accrual, redemption reservation and capture, refund-safe adjustments, imports, segmentation, scheduled campaigns, and attribution. A responsive reference guest wallet uses OIDC Authorization Code and PKCE, while OpenAPI, JSON Schema, and HTTP conformance tests support the portable /lip/v1 contract.
The main trade-off is implementation ownership. Teams can self-host the reference platform with Docker and choose SQLite or PostgreSQL, but they must handle deployment and connect external customer authentication. The local Admin dashboard supports program drafts, publishing, and rollback, giving operators program controls without turning the product into a no-code service. Choose Loyalty Interchange Protocol when extensibility, portability, and control over the loyalty stack matter. Consider an alternative if the priority is a fully managed, no-code restaurant marketing system with minimal engineering involvement.
