# Building with Syncs

In the Sync model, **Chift builds the integration and triggers the flows**. Rather than calling connector data yourself, you delegate the synchronisation to Chift: we define it with you and run it on an event or a schedule, with no integration code on your side.

New to the terms *connector*, *consumer*, and *connection*? See [How it works](/developer-guides/how-it-works) first.

## How a sync works

A **sync** is a synchronisation between two of Chift's APIs, built and maintained by Chift. It contains one or more **flows**, each triggered by an event or a timer (for example, every night at 4 AM), running a process — such as *get invoices and inject them into accounting* — for every consumer linked to the sync.

During onboarding you can add **mappings**, correspondences your end-user confirms — for example matching tax rates between their POS and their accounting software.

## What stays the same

You still create consumers and connections exactly as in the [Unified API model](/developer-guides/unified-api/overview) — a sync runs on top of those connections. What you don't write is the integration logic that moves the data; Chift owns that.
