# How to Send an Email Notification Using Omnisend - Back In Stock APP

The **Back in Stock** app allows you to automatically notify customers when an out-of-stock product becomes available again. By integrating it with **Omnisend**, you can send branded and automated restock email notifications to your subscribers.
### Prerequisites
Before you begin, make sure:
* The **Back in Stock** app is installed on your Shopify store.
* Your **Omnisend** account is connected to your Shopify store.
* The integration between the Back in Stock app and Omnisend is enabled.

# Steps:

1. **Generate an API Key in Omnisend:** Log in to your **Omnisend** account → Go to **Store Settings** → Click **API Keys** from the left-hand menu → Click **Create API Key** → Enter a name (e.g., **"Back in Stock Integration"**) → Select the required permissions → Click **Create API Key** → Copy the generated API key and save it in a secure location.

|| You can also follow Omnisend's official documentation to generate an API key: [Generate an API Key in Omnisend](https://support.omnisend.com/en/articles/1061890-generate-an-api-key-in-omnisend)


2. **Verify the Omnisend API Key** :Open the **Back in Stock Alerts** app → Navigate to **General Settings** → Select the **Notification** tab → Choose **Omnisend** under **E-mail Integration** → Paste your **Omnisend API Key** into the **Omnisend API Key** field → Click **Verify API Key** → Once the API key is verified successfully, click **Save** to complete the integration.

3. **Verify the Integration and Review the Workflows**:  After clicking **Verify API Key**, the **Back in Stock** app will automatically create two workflows in your **Omnisend** account:
**To view these workflows:**
**Omnisend Dashboard → Automation →** Verify that both workflows (**Back in Stock – Thank You for Subscribing** and **Back in Stock – Available Again**) are created and have the **Enabled** status.
* **Back in Stock – Thank You for Subscribing** – Sends a confirmation email immediately after a customer subscribes to receive back-in-stock notifications.
* **Back in Stock – Available Again** – Sends an email notification to subscribed customers when the product is back in stock.

Once both workflows are **Enabled**, your back-in-stock email notifications are successfully configured and will be sent automatically through **Omnisend**.
