Medusa V2 Store API Reference

This API reference includes Medusa's Store APIs, which are REST APIs exposed by the Medusa application. They are used to create a storefront for your commerce store, such as a webshop or a commerce mobile app.

All API Routes are prefixed with /store. So, during development, the API Routes will be available under the path http://localhost:9000/store. For production, replace http://localhost:9000 with your Medusa application URL.

Authentication

There are two ways to send authenticated requests to the Medusa application: Using a JWT token or using a Cookie Session ID.

Bearer Authorization with JWT Tokens

Use a JWT token in a request's bearer authorization header to send authenticated requests. Authentication state is managed by the client, which is ideal for Jamstack applications and mobile applications.

How to Obtain the JWT Token

JWT tokens are obtained by sending a request to the authentication route passing it the customer's email and password in the request body.

For example:

Code
1curl -X POST '{backend_url}/auth/customer/emailpass' \2-H 'Content-Type: application/json' \3--data-raw '{4  "email": "user@example.com",5  "password": "supersecret"6}'

If authenticated successfully, an object is returned in the response with the property token being the JWT token.

How to Use the JWT Token

Pass the JWT token in the authorization bearer header:

Terminal
❯Authorization: Bearer {jwt_token}

Cookie Session ID

When you authenticate a customer and create a cookie session ID for them, the cookie session ID is passed automatically when sending the request from the browser, or with tools like Postman.

How to Obtain the Cookie Session

To obtain a cookie session ID, you must have a JWT token for bearer authentication.

Then, send a request to the session authentication API route. To view the cookie session ID, pass the -v option to the curl command:

Code
1curl -v -X POST '{backend_url}/auth/session' \2--header 'Authorization: Bearer {jwt_token}'

The headers will be logged in the terminal as well as the response. You should find in the headers a Cookie header similar to this:

Terminal
❯Set-Cookie: connect.sid=s%3A2Bu8BkaP9JUfHu9rG59G16Ma0QZf6Gj1.WT549XqX37PN8n0OecqnMCq798eLjZC5IT7yiDCBHPM;

How to Use the Cookie Session ID in cURL

Copy the value after connect.sid (without the ; at the end) and pass it as a cookie in subsequent requests as the following:

Code
1curl '{backend_url}/store/products' \2-H 'Cookie: connect.sid={sid}'

Where {sid} is the value of connect.sid that you copied.

Including Credentials in the Fetch API

If you're sending requests using JavaScript's Fetch API, you must pass the credentials option with the value include to all the requests you're sending. For example:

Code
1fetch(`<BACKEND_URL>/store/products`, {2  credentials: "include",3})

Publishable API Key

You must pass a publishable API key in the header of your requests to the store API routes.

Publishable API Keys sets the scope of your request to one or more sales channels. This ensures you only retrieve products available in the publishable API key's sales channels, retrieve correct inventory details, and associate placed orders with the specified sales channel.

How to Create a Publishable API Key

Create a publishable API key either using the admin REST APIs, or using the Medusa Admin.

How to Use a Publishable API Key

You pass the publishable API key in the header x-publishable-api-key in all your requests to the store APIs.

For example:

Code
1curl 'http://localhost:9000/store/products' \2-H 'x-publishable-api-key: {your_publishable_api_key}'

Where {your_publishable_api_key} is the token of the publishable API key.

HTTP Compression

If you've enabled HTTP Compression in your Medusa configurations, and you want to disable it for some requests, you can pass the x-no-compression header in your requests:

Terminal
❯x-no-compression: true

Select Fields and Relations

Many API Routes accept a fields query that allows you to select which fields and relations should be returned in a record. Fields and relations are separated by a comma ,.

For example:

Code
curl 'localhost:9000/store/products?fields=title,handle'

This returns only the title and handle fields of a product.

Fields Operator

By default, only the selected fields and relations are returned in the response.

Before every field or relation, you can pass one of the following operators to change the default behavior:

• +: Add the field to the fields returned by default. For example, +title returns the title field along with the fields returned by default.
• -: Remove the field from the fields returned by default. For example, -title removes the title field from the fields returned by default.

Select Relations

To select a relation, pass to fields the relation name prefixed by *. For example:

Code
curl 'localhost:9000/store/products?fields=*variants'

This returns the variants of each product.

Select Fields in a Relation

The * prefix selects all fields of the relation's data model.

To select a specific field, pass a .<field> suffix instead of the * prefix. For example, variants.title.

To specify multiple fields, pass each of the fields with the <relation>.<field> format, separated by a comma.

For example:

Code
curl 'localhost:9000/store/products?fields=variants.title,variants.sku'

This returns the variants of each product, but the variants only have their id, title, and sku fields. The id is always included.

Query Parameter Types

This section covers how to pass some common data types as query parameters. This is useful if you're sending requests to the API Routes and not using our JS Client. For example, when using cURL or Postman.

Strings

You can pass a string value in the form of <parameter_name>=<value>.

For example:

Code
curl "http://localhost:9000/store/products?title=Shirt"

If the string has any characters other than letters and numbers, you must encode them.

For example, if the string has spaces, you can encode the space with + or %20:

Code
curl "http://localhost:9000/store/products?title=Blue%20Shirt"

You can use tools like this one to learn how a value can be encoded.

Integers

You can pass an integer value in the form of <parameter_name>=<value>.

For example:

Code
curl "http://localhost:9000/store/products?offset=1"

Boolean

You can pass a boolean value in the form of <parameter_name>=<value>.

For example:

Code
curl "http://localhost:9000/store/products?is_giftcard=true"

Date and DateTime

You can pass a date value in the form <parameter_name>=<value>. The date must be in the format YYYY-MM-DD.

For example:

Code
curl -g "http://localhost:9000/store/products?created_at[$lt]=2023-02-17"

You can also pass the time using the format YYYY-MM-DDTHH:MM:SSZ. Please note that the T and Z here are fixed.

For example:

Code
curl -g "http://localhost:9000/store/products?created_at[$lt]=2023-02-17T07:22:30Z"

Array

Each array value must be passed as a separate query parameter in the form <parameter_name>[]=<value>. You can also specify the index of each parameter in the brackets <parameter_name>[0]=<value>.

For example:

Code
curl -g "http://localhost:9000/store/products?sales_channel_id[]=sc_01GPGVB42PZ7N3YQEP2WDM7PC7&sales_channel_id[]=sc_234PGVB42PZ7N3YQEP2WDM7PC7"

Note that the -g parameter passed to curl disables errors being thrown for using the brackets. Read more here.

Object

Object parameters must be passed as separate query parameters in the form <parameter_name>[<key>]=<value>.

For example:

Code
curl -g "http://localhost:9000/store/products?created_at[$lt]=2023-02-17&created_at[$gt]=2022-09-17"

Pagination

Query Parameters

In listing API Routes, such as list products, you can control the pagination using the query parameters limit and offset.

limit is used to specify the maximum number of items to be returned in the response. offset is used to specify how many items to skip before returning the resulting records.

Use the offset query parameter to change between pages. For example, if the limit is 50, at page 1 the offset should be 0; at page 2 the offset should be 50, and so on.

For example:

Code
curl "http://localhost:9000/store/products?limit=5"

Response Fields

In the response of listing API Routes, aside from the records retrieved, there are three pagination-related fields returned:

• limit: the maximum number of items that can be returned in the response.
• offset: the number of items that were skipped before the records in the result.
• count: the total number of available items of this data model. It can be used to determine how many pages are there.

For example, if the count is 100 and the limit is 50, divide the count by the limit to get the number of pages: 100/50 = 2 pages.

Sort Order

The order field (available on API Routes that support pagination) allows you to sort the retrieved items by a field of that item.

For example, pass the query parameter order=created_at to sort products by their created_at field:

Code
curl "http://localhost:9000/store/products?order=created_at"

By default, the sort direction is ascending. To change it to descending, pass a dash (-) before the field name.

For example:

Code
curl "http://localhost:9000/store/products?order=-created_at"

This sorts the products by their created_at field in the descending order.
