DeliveryCheckout API

DeliveryCheckout API is an integration service for communication between nShift Checkout and your webshop.

DeliveryCheckout API uses a REST API framework for communication with JSON as data carrier offering a number of functions.

With DeliveryCheckout API you can:

  • Present delivery options in your webshop.

  • Prepare shipments

  • Upload agent lists

The REST API endpoints are only accessible via HTTPS and are located at api.unifaun.com.

Before getting started you need to know your developer ID and create an API key.

Tip

We recommend that you provide Svea with a fallback solution for every checkout session in case Svea doesn't get a response from our API, for example, due to maintenance.

This way you ensure that your customers are always presented with shipping options.
