# How to Manage Customer Groups

In this document, you’ll learn how to use the customer groups admin APIs to manage customer groups and their associated customers and price lists.

## Overview

Using the Admin API you can manage customer groups by creating, retrieving, updating, and deleting them. You can also manage the customers in a customer group.

Using the PriceList API you can specify among the conditions the customer groups that the prices will apply to.

This guide covers how to use these APIs to perform these tasks.

---

## Prerequisites

### Medusa Components

It is assumed that you already have a Medusa server installed and set up. If not, you can follow our [quickstart guide](../../quickstart/quick-start.mdx) to get started.

### JS Client

This guide includes code snippets to send requests to your Medusa server using Medusa’s JS Client, JavaScript’s Fetch API, or cURL.

If you follow the JS Client code blocks, it’s assumed you already have [Medusa’s JS Client](../../js-client/overview.md) installed and have [created an instance of the client](../../js-client/overview.md#configuration).

### Authenticated Admin User

You must be an authenticated admin user before following along with the steps in the tutorial.

You can learn more about [authenticating as an admin user in the API reference](https://docs.medusajs.com/api/admin/#section/Authentication).

## Create Customer Groups

You can create a customer group by sending a request to the Create Customer Group endpoint:

<Tabs groupId="request-type" wrapperClassName="code-tabs">
<TabItem value="client" label="Medusa JS Client" default>

```jsx
medusa.admin.customerGroups.create({
  name: "VIP",
})
.then(({ customer_group }) => {
  console.log(customer_group.id)
})
```

</TabItem>
<TabItem value="fetch" label="Fetch API">

```jsx
fetch(`<SERVER_URL>/admin/customer-groups`, {
  method: "POST",
  credentials: "include",
  headers: {
    "Content-Type": "application/json",
  },
  body: JSON.stringify({
    name: "VIP",
  }),
})
.then((response) => response.json())
.then(({ customer_group }) => {
  console.log(customer_group.id)
})
```

</TabItem>
<TabItem value="curl" label="cURL">

```bash
curl -L -X POST '<SERVER_URL>/admin/customer-groups' \
-H 'Authorization: Bearer <API_TOKEN>' \
-H 'Content-Type: application/json' \
--data-raw '{
    "name": "VIP"
}'
```

</TabItem>
</Tabs>

This request requires the `name` parameter and optionally accepts the `metadata` object parameter to be passed in the body. It returns the created customer group.

---

## List Customer Groups

You can get a list of all customer groups by sending a request to the List Customer Groups endpoint:

<Tabs groupId="request-type" wrapperClassName="code-tabs">
<TabItem value="client" label="Medusa JS Client" default>

```jsx
medusa.admin.customerGroups.list()
.then(({ customer_groups, limit, offset, count }) => {
  console.log(customer_groups.length)
})
```

</TabItem>
<TabItem value="fetch" label="Fetch API">

```jsx
fetch(`<SERVER_URL>/admin/customer-groups`, {
  credentials: "include",
})
.then((response) => response.json())
.then(({ customer_groups, limit, offset, count }) => {
  console.log(customer_groups.length)
})
```

</TabItem>
<TabItem value="curl" label="cURL">

```bash
curl -L -X GET '<SERVER_URL>/admin/customer-groups' \
-H 'Authorization: Bearer <API_TOKEN>'
```

</TabItem>
</Tabs>

This request returns an array of customer groups, as well as pagination fields.

You can also pass filters and other selection query parameters to the request. Check out the [API reference](https://docs.medusajs.com/api/admin/#tag/Customer-Group/operation/GetCustomerGroups) for more details on available query parameters.

## Use Customer Groups as Conditions in a Price List

When you create or update a price list, you can specify one or more customer groups as conditions for the price list. You can learn how to do that in the [PriceList API documentation](../backend/price-lists/use-api.mdx).
