This guide assumes you've established a Craft site and you're setting up a new store for the first time.
Start by creating an account (opens new window) via Snipcart. Copy your API keys from Account → API Keys in Snipcart to Settings → Snipcart on your Craft site.
Everything here is off by default, but you can configure a number of options that don't require any extra code unless you'd prefer your own markup, field types, and integrations.
Order Comments and gift notes are explained more in their own section, and while email notifications are ready to go you can learn more about using your own templates for them in Custom Email Notifications.
There's nothing to set here, but this part is important: use this URL to link Snipcart and Craft with webhooks.
Caching is enabled and somewhat conservative to balance timeliness and speed, but here you can adjust that and optionally turn on webhook logging that could help with troubleshooting.
If you've set up a ShipStation account and want the Snipcart plugin to get live rates or forward orders, this is where you'll need to add your credentials along with a Ship From address.
See the Shipments page for more about how ShipStation integration works.
