# ChannelEngine

> ChannelEngine is a marketplace integration and multichannel e-commerce platform (Leiden, Netherlands; backed by General Catalyst) that lets brands and retailers connect their ERP, PIM, WMS, or webstore once and sell across 1,300+ marketplaces and channels. It exposes three REST APIs — Merchant, Channel, and Channel Management — with API-key auth, JSON envelopes, page-based pagination, header-based rate limiting, and webhooks.
