# Gelato Sync > Gelato Sync is a free app for OpoShop stores. A merchant connects their own Gelato account, picks products they already designed in Gelato, and adds them to their OpoShop store with a price. The design stays in Gelato. Each paid order for one of those products is listed in Gelato Sync. Sending those orders to Gelato automatically, and bringing the tracking number back to OpoShop, is still being tested and is not switched on yet. This app is made for OpoShop. Merchants install it from the OpoShop App Store and use it inside their store admin. ## Pages - What it does: https://gelatosync.com/ - Privacy: https://app.gelatosync.com/privacy - Terms: https://app.gelatosync.com/terms - What's new: https://app.gelatosync.com/api/release-notes - Support: brandon@tryfound.io ## Machine interfaces - API contract (OpenAPI): https://app.gelatosync.com/openapi.json - API docs (Swagger): https://app.gelatosync.com/docs - Fuller LLM context: https://app.gelatosync.com/llms-full.txt The API is used by the app itself, with a session created when a merchant opens Gelato Sync from OpoShop.
