# Migrate to read\_locations scope

This guide describes how to migrate your app with `read_inventory` scope to access Location GraphQL fields, which became [a requirement in API version 2024-07](https://shopify.dev/changelog/the-location-object-requires-read_locations-scope).

***

## Requirements

* You've built an [inventory management](https://shopify.dev/docs/apps/build/orders-fulfillment/inventory-management-apps) app that accesses location data.
* Your app currently has the `read_inventory` or `write_inventory` scope.
* Your app queries Location GraphQL fields.

Note

As of GraphQL API version `2024-07`, the [Location](https://shopify.dev/docs/api/storefront/latest/objects/Location) fields require the `read_locations` scope. Apps without this scope will receive access denied errors when querying location data.

***

## Step 1: Determine if your app needs migration

Your app needs migration if:

* Your app queries Location GraphQL fields
* Your app has `read_inventory` or `write_inventory` scope but lacks `read_locations`
* You're receiving access denied errors when querying location data

***

## Step 2: Update your app's permissions

Note

Tip: If you [configure your app using Shopify CLI](https://shopify.dev/docs/apps/build/cli-for-apps/app-configuration), then your app will automatically use [Shopify managed installation](https://shopify.dev/docs/apps/build/authentication-authorization/app-installation). You can skip this step.

When you've determined that your app needs `read_locations` scope, you can update your app for [new installations](#new-installations) and [existing installations](#existing-installations).

### New installations

For new installations, include the `read_locations` scope in the permissions that your app requests as part of [authorization code grant](https://shopify.dev/docs/apps/build/authentication-authorization/access-tokens/authorization-code-grant).

### Existing installations

For existing installations of your app, you can use the `request_granular_access_scopes` REST endpoint to request the `read_locations` scope based on the inventory access scopes your app is already granted. You should make a request to the `request_granular_access_scopes` REST endpoint for each shop where your app is installed.

* If your app has the `read_inventory` or `write_inventory` access scope, then it can request the `read_locations` access scope.

The following example request adds the `read_locations` scope to an existing installation of an inventory management app that has `read_inventory` scope.

## POST https://{shop}.myshopify.com/api/{api\_version}/graphql.json

## REST body

```json
{
  "requested_scopes": [
    "read_locations"
  ]
}
```

## JSON response

```json
HTTP/1.1 200 OK
{
  "access_scopes": [
    {
      "handle": "read_inventory"
    },
    {
      "handle": "read_locations"
    }
  ]
}
```

The following example request demonstrates an error returned if an app does not have the `read_inventory` or `write_inventory` access scope but requests the `read_locations` access scope.

## POST https://{shop}.myshopify.com/api/{api\_version}/graphql.json

## REST body

```json
{
  "requested_scopes": [
    "read_locations"
  ]
}
```

## JSON response

```json
HTTP/1.1 422 Unprocessable Entity
{
  "errors": {
    "requested_scopes": "Missing required scopes: \"read_locations\" requires \"read_inventory\" or \"write_inventory\"."
  }
}
```

***

## Step 3: Verify your migration

After implementing scope expansion, you can verify that your app can now access location data by making a GraphQL query to fetch locations:

```graphql
query getLocations {
  locations(first: 10) {
    edges {
      node {
        id
        name
      }
    }
  }
}
```

If your scope expansion was successful, this query will return location data. If you encounter any errors, ensure that:

1. The scope expansion request was successful
2. The access token you're using for the GraphQL request is the updated token
3. Your app has properly handled any authorization errors
