The Back In Stock Notifications API allows you to manage customer requests to receive notifications when out-of-stock items become available. 

With this API, you can:
+ Increase sales and customer satisfaction with personalized notifications.
+ Collect insights on requested items that are currently unavailable.
+ Effectively manage inventory and adjust restocking strategy.

Learn more about [notifying customers when products are back in stock](https://support.wix.com/en/article/wix-stores-notifying-customers-when-products-are-back-in-stock).

To use the Back In Stock Notifications API, import { backInStockNotifications } from the ‘wix-ecom-backend’ module:
``` javascript 
import { backInStockNotifications } from `wix-ecom-backend`;
```

## Before you begin
It’s important to note the following points before starting to code:
+ To start collecting back in stock requests, the `collectionStates` must be set to `true`. Use [`startCollectingRequests()`](/back-in-stock-settings/start-collecting-requests) to update collection states, or [update in a site’s dashboard](https://www.wix.com/my-account/site-selector/?buttonText=Go%20to%20Back-in-Stock&title=Select%20a%20Site&autoSelectOnSingleSite=true&actionUrl=https://www.wix.com/dashboard/{{metaSiteId}}/store/back-in-stock).
+ For emails to send with the [`reportItemsBackInStock()`](/back-in-stock-notifications/report-items-back-in-stock) function, automations must be [activated in the site’s dashboard](https://www.wix.com/my-account/site-selector/?buttonText=Go%20to%20Back-in-Stock&title=Select%20a%20Site&autoSelectOnSingleSite=true&actionUrl=https://www.wix.com/dashboard/{{metaSiteId}}/store/back-in-stock) first.
+ [Customize the design of the notification email](https://support.wix.com/en/article/wix-stores-notifying-customers-when-products-are-back-in-stock#customizing-the-notification-email) that will be sent.

## Terminology
+ **Notification request:** The object that is created when a customer wants to be notified when an out-of-stock item becomes available. The back in stock notification request contains information about the item and an email address to contact when it’s back in stock.

## Permissions information
The following functions in Back In Stock Notifications API are restricted and only run if you elevate permissions using the `wix-auth` [`elevate()`](https://www.wix.com/velo/reference/wix-auth/elevate) function:

+ [`deleteBackInStockNotificationRequest()`](/back-in-stock-notifications/delete-back-in-stock-notification-request)
+ [`getBackInStockNotificationRequest()`](/back-in-stock-notifications/get-back-in-stock-notification-request)
+ [`getBackInStockNotificationRequestsCountByCatalogReferences()`](/back-in-stock-notifications/get-back-in-stock-notification-requests-count-by-catalog-references)
+ [`markAsNotificationSent()`](/back-in-stock-notifications/mark-as-notification-sent)
+ [`queryBackInStockNotificationRequests()`](/back-in-stock-notifications/query-back-in-stock-notification-requests)
