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.

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.

4. Customize the Email Templates : After the workflows are created, you can customize the Back in Stock email templates according to your store's branding and messaging.

You can also personalize your emails using the placeholders below. Omnisend will automatically replace these placeholders with the customer's information, product details, and your store information when the email is sent.

Available Placeholders:

• [[event.customer_name]] – Customer's name
• [[event.customer_email]] – Customer's email address
• [[event.product_title]] – Product title
• [[event.product_name]] – Product name
• [[event.product_url]] – Product URL
• [[event.product_image]] – Product image
• [[event.store_name]] – Store name
• [[event.store_email]] – Store email address

These placeholders allow you to create personalized subscription confirmation and back-in-stock notification emails for your customers.
