Lightspeed Commerce Inc. · Ecommerce & storefront platforms
The Ecwid App Market is the developer distribution channel for Ecwid by Lightspeed — an ecommerce platform whose core value proposition is embedding a store into any existing website or selling across channels. Developers build public apps that connect via OAuth 2.0 and can render UI inside the merchant's Ecwid control panel or integrate purely as backend connectors and widgets. The REST API is the primary surface, capped at 600 requests/minute per token, with private single-store apps able to use secret API tokens and public apps required to use OAuth plus webhooks for events.
Getting listed is free but contractual: developers sign a partner agreement and pass a review that typically takes 1–2 business days; apps wiring in unauthorized payment processors, or whose main purpose is advertising, are rejected. On monetization, Ecwid acts as merchant of record through its billing — collecting subscription or usage revenue and paying developers 80% of net app revenue on a quarterly cycle. Choose Ecwid to reach embedded and omnichannel SMB sellers across the Lightspeed ecosystem with a straightforward OAuth + REST model.
Ecwid review is a manual, contact-the-team process: after building you request submission, fill in the app details page, and the team reviews before publishing to all merchants.
