By default, the back in stock is only enabled on Product pages. Before the days of the app embed, you could easily edit the code and make it fire elsewhere.

Does anyone know a solution? I really need it to be enabled on collection pages as well. I have spent hours and cannot crack this.

I’m using the Horizon theme.

Hi ​@long,

Welcome to the Klaviyo Community, and thanks for posting this question. While our new Back In Stock forms better allow marketers who aren’t code-savvy to add forms to their site, I do understand the importance of enabling Back In Stock functionality on other pages.

My recommendation here would be to set up Back in Stock via API, which involves creating a custom form, and then triggering the Create Back in Stock Subscription or Create Client Back in Stock Subscription endpoint to fire when that form is submitted. We have a guide on our developer portal that goes through this process, and might be worth checking out!
