How to Use Sales Channels in Storefronts

In this document, you’ll learn how to use sales channels in your storefront.

Overview

In your storefront, you can filter products by sales channels. You can also associate carts with a sales channel.

This guide explains how to perform these operations using the Storefront APIs.

Alternative Approach: Publishable API keys

This guide covers how to pass the sales channel ID into different requests to retrieve or process data associated with the sales channel.

An alternative approach is to use Publishable API keys. You can learn how to use them in the following documents:


Prerequisites

Medusa Components

It's assumed that you already have a Medusa backend installed and set up. If not, you can follow our quickstart guide to get started.

It is also assumed you already have a storefront set up. It can be a custom storefront or one of Medusa’s storefronts. If you don’t have a storefront set up, you can install the Next.js starter storefront.

JS Client

This guide includes code snippets to send requests to your Medusa backend using Medusa’s JS Client, among other methods.

If you follow the JS Client code blocks, it’s assumed you already have Medusa’s JS Client installed and have created an instance of the client.

Medusa React

This guide also includes code snippets to send requests to your Medusa backend using Medusa React, among other methods.

If you follow the Medusa React code blocks, it's assumed you already have Medusa React installed and have used MedusaProvider higher in your component tree.

For requests that use the cart, it's also assumed you already have used CartProvider higher in your component tree.


Filter Products by Sales Channel

To filter products by a specific sales channel, pass the sales_channel_id query parameter to the List Products endpoint:

medusa.products.list({
sales_channel_id: [
salesChannelId,
],
})
.then(({ products, limit, offset, count }) => {
console.log(products.length)
})

The sales_channel_id query parameter is an array of sales channel IDs. You can pass more than one sales channel.

The request returns an array of products. These are the products that are available in the sales channel.


Associate a Cart with a Sales Channel

When Creating a Cart

To associate a sales channel with a cart while creating it, you can pass the sales_channel_id request body parameter with the ID of the sales channel:

medusa.carts.create({
sales_channel_id: salesChannelId,
})
.then(({ cart }) => {
console.log(cart.id)
})

The request returns the created cart.

Updating an Existing Cart

You can update the sales channel of an existing cart by passing the sales_channel_id request body parameter with the ID of the sales channel:

medusa.carts.update(cartId, {
sales_channel_id: salesChannelId,
})
.then(({ cart }) => {
console.log(cart.id)
})

The request returns the updated cart.
