ShipEngine

ShipEngine connects your carrier accounts (USPS/Stamps.com, UPS, FedEx, DHL Express) to Cartly. Shoppers see live rates at checkout; you rate-shop and buy a shipping label with a tracking number and printable PDF straight from the order page.

## Setup

1. In ShipEngine (app.shipengine.com) connect your carriers and copy your API key (Settings -> API Management).

2. In Cartly, open Settings -> Integrations -> ShipEngine, paste the key, choose your region (US/EU), pick which carriers to quote, and set your ship-from address.

3. Test Connection to activate.
