Shipping Architecture Overview

This document gives an overview of the shipping architecture and its four most important components.

Introduction

In Medusa, the Shipping architecture relies on 4 components: Fulfillment ProviderShipping ProfilesShipping Options, and Shipping Methods.

The distinction between the four is important. It has been carefully planned and put together to support all the different ecommerce use cases and shipping providers that can be integrated.

It’s also constructed to support multiple regions, provide different shipment configurations and options for different product types, provide promotional shipments for your customers, and much more.

Summary

  • Fulfillment Provider: Fulfillment providers are plugins or Services used to ship the products to your customers, whether physically or virtually. An example of a fulfillment provider would be FedEx.
  • Shipping Profiles: created by the admin. They are used to group products that should be shipped in a different manner than the default. Shipping profiles can have multiple shipping options.
  • Shipping Options: created by the admin and belong to a shipping profile. They are specific to certain regions and can have cart conditions. They use an underlying fulfillment provider. Once a customer checks out, they can choose the shipping option that’s available and most relevant to them.
  • Shipping Method: created when the customer chooses a shipping option on checkout. The shipping method is basically a copy of the shipping option, but with values specific to the customer and the cart it’s associated with. When the order is placed, the shipping method will then be associated with the order and fulfilled based on the integration with the fulfillment provider.

Shipping Architecture

Fulfillment Provider

A Fulfillment Provider in Medusa is a method to handle shipping products in selected regions. It is not associated with a cart, customer, or order in particular.

It provides the necessary implementation to create Fulfillments for orders and ship items to customers. They can also be used for order returns and swaps.

Fulfillment Providers can be integrated with third-party services that handle the actual shipment of products. An example of a Fulfillment Provider is FedEx.

Fulfillment Providers can also be related to a custom way of handling fulfillment operations. An example of that is Medusa’s manual fulfillment provider plugin which provides a minimal implementation of a fulfillment provider and allows store operators to manually handle order fulfillments.

How Fulfillment Provider is Created

A Fulfillment Provider is essentially a Medusa Service with a unique identifier, and it extends the Copy to Clipboard provided by the Copy to Clipboard package. It can be created as part of a plugin, or it can be created just as a Service file in your Medusa server.

As a developer, you will mainly work with the Fulfillment Provider when integrating a fulfillment method in Medusa.

When you run your Medusa server, the Fulfillment Provider will be registered on your server if it hasn’t been already.

Once the Fulfillment Provider is added to the server, the store operator will be able to associate on the Medusa Admin the Fulfillment Provider with shipping options.

FulfillmentProvider Entity Overview

The Copy to Clipboard entity only has 2 attributes: Copy to Clipboard to indicate if the fulfillment provider is installed and its value is a boolean; and Copy to Clipboard which is the unique identifier that you define in the Fulfillment Provider Service.

Shipping Profile

Shipping profiles are the highest in the hierarchy in the shipping architecture.

Shipping profiles are created by the admin. The admin can specify the name of the shipping profile which will be a name that the customer can see.

A shipping profile is not associated with any fulfillment providers. It has multiple shipping options that can be associated with different providers.

Purpose of Shipping Profile

Shipping profiles are used to group products that can be shipped in the same manner.

The default shipping profile is one that groups all of your store’s products. You also get a shipping profile that’s specific to gift cards. This is because, generally speaking, all products would be delivered similarly, whereas gift cards would be delivered in different behavior.

Although this might be the general case, there are still some use cases where you will have a set of products that should be shipped differently than others.

For example, shipping heavy items might be more expensive than others, which would enforce different price rates. In that case, you can create a new shipping profile that groups together heavy products. This would allow you to give these products more suitable price rates when creating their shipping options.

ShippingProfile Entity Overview

The Copy to Clipboard entity can have a set of Copy to Clipboard instances. These would be the products the shipping profile is providing shipping options for.

The Copy to Clipboard has a Copy to Clipboard attribute that can be Copy to Clipboard, Copy to Clipboard, or Copy to Clipboard.

The Copy to Clipboard entity also has an array of Copy to Clipboard instances.

Shipping Option

After the admin adds a shipping profile, they can add shipping options that belong to that shipping profile from the admin dashboard.

Shipping options have a set of conditions like the region they’re available in or cart-specific conditions. For example, if your company operates in the United States as well as Germany, you might use a different shipping option for each of the two countries.

Among the configurations that the admin has to set when creating a shipping option is specifying the fulfillment provider it uses. This means that when you create a plugin for a fulfillment provider, that provider needs to be chosen as the fulfillment provider of a shipping option to be used in the store.

Shipping options are only shown to a customer during checkout if their cart satisfies the option’s conditions. Also, as they belong to a shipping profile, they’re only shown when products that belong to the same shipping profile are in the cart.

Purpose of Shipping Option

The first purpose that a shipping option has is showing the customer during checkout what shipping options are available for them.

Then, once the customer chooses a shipping option, that shipping option is used to create a shipping method with details specific to the customer and their cart. Then, the shipping method is associated with the cart, and the shipping option remains untouched.

Think of a shipping option as a template defined by the admin that indicates what data and values the shipping method should have when it’s chosen by the customer during checkout.

ShippingOption Entity Overview

The Copy to Clipboard entity belongs to the Copy to Clipboard entity.

The Copy to Clipboard entity also belongs to a Copy to Clipboard. This can be either a custom third-party provider or one of Medusa’s default fulfillment providers.

It has the Copy to Clipboard attribute to indicate whether the shipping option’s rate is Copy to Clipboard by the provider or a fixed Copy to Clipboard price. It also has the Copy to Clipboard attribute to set an amount for the shipping option if the Copy to Clipboard is Copy to Clipboard.

Copy to Clipboard also belongs to a Copy to Clipboard, which resembles one or more countries. This defines where the shipping option is available.

Copy to Clipboard has a set of Copy to Clipboard instances. The Copy to Clipboard entity allows defining cart rules which determine whether the shipping option will be available or not for a customer during checkout. For example, you can set a minimum subtotal amount for a shipping option to be available for a customer’s cart.

The Copy to Clipboard attribute is used to indicate whether the shipping option is used for shipping orders or returning orders. Shipping options can only be used for one or the other.

The Copy to Clipboard attribute is used to specify any data necessary for fulfilling the shipment based on the underlying fulfillment provider. When you integrate a fulfillment provider, you can check in that provider’s documentation for any data necessary when creating a new shipment.

The Copy to Clipboard attribute does not have any specific format. It’s up to you to choose whatever data is included here.

Shipping Method

Unlike the previous two components, a shipping method is not created by the admin. It’s created when a Copy to Clipboard request is sent to Copy to Clipboard after the customer chooses a shipping option.

The shipping method will be created based on the chosen shipping option and it’ll be associated with the customer’s cart. Then, when the order is placed, the shipping method is associated with the order.

A shipping method can be fulfilled automatically or manually through the admin dashboard. This is based on the fulfillment provider associated with the shipping option the shipping method is based on.

Shipping Method Purpose

It’s important to understand the distinction between shipping methods and shipping options. Shipping options are templates created by the admin to indicate what shipping options should be shown to a customer. This provides customization capabilities in a store, as an admin is free to specify configurations for that option such as what fulfillment provider it uses or what are its rates.

When handling the order and fulfilling it, you, as a developer, will be mostly interacting with the shipping method.

This separation allows for developers to implement the custom integration with third-party fulfillment providers as necessary while also ensuring that the admin has full control of their store.

ShippingMethod Entity Overview

A lot of the shipping method’s attributes are similar to the shipping option’s attribute.

The Copy to Clipboard entity belongs to a Copy to Clipboard.

Similar to the Copy to Clipboard attribute explained for the Copy to Clipboard entity, a Copy to Clipboard has a similar Copy to Clipboard attribute that includes all the data to be sent to the fulfillment provider when fulfilling the order.

The Copy to Clipboard belongs to a Copy to Clipboard. This is the cart the customer is checking out with.

The Copy to Clipboard also belongs to the Copy to Clipboard entity. This association is accomplished when the order is placed.

The Copy to Clipboard instance holds a Copy to Clipboard attribute, which will either be the flat rate price or the calculated price.
