How to Track Out-of-Stock Product Views & Notify Users via Infobip

Start a Business

Topic summary

A Shopify store owner seeks to implement a system that tracks when customers view out-of-stock products and allows them to opt in for restock notifications via phone or email through Infobip integration.

Specific Requirements:

  • Track users viewing out-of-stock items
  • Collect and store customer contact details (phone/email)
  • Trigger automated notifications through Infobip when products are restocked
  • Utilize Shopify’s native webhooks or APIs if possible

Response Provided:
A community member suggests using third-party “Back in Stock” apps from the Shopify App Store, noting that Shopify’s native email platform doesn’t currently support back-in-stock notifications. Klaviyo is mentioned as an alternative platform with built-in back-in-stock functionality.

Status: The discussion remains open, as no solution specifically addressing Infobip integration has been provided. The original poster’s question about custom development or native Shopify implementation for Infobip remains unanswered.

Hi Shopify Community,

I’m looking for a way to track when a user views a product that is out of stock and allow them to opt in for a notification when the item is back in stock. Ideally, the user would provide their phone number and/or email, and once the product is restocked, they would receive a notification via Infobip.

I found several apps that offer similar functionality, but none of them integrate with Infobip. I want to know if there’s a way to implement this natively within Shopify or through custom development. Specifically:

How can I track users who view an out-of-stock product?
What’s the best approach to store their contact details for back-in-stock notifications?
Can Shopify’s native webhooks or APIs be used to trigger a notification when stock is replenished?
Has anyone integrated Shopify with Infobip for automated notifications before?
I’d appreciate any insights or suggestions on how to make this work. Thanks in advance!

The easiest solution to this is to use a 3rd party Back in Stock app.

The native Shopify email platform doesn’t have Back in Stock notifications activated yet. If you are using Klaviyo they also have a Back in Stock code you can install on your theme.

I’ve also written a blog post about why back in stock is important: https://www.tinabar.com/blog/an-overlooked-opportunity-the-back-in-stock-button?rq=back%20in%20stock
