I looked into this, and looked through our API endpoints to see if we have any endpoints that you could use to pull this information. At this time, there isn’t a method to pull that back in stock data out of Klaviyo via API. That being said, I definitely see how this would be useful, and I’m happy to reach out to our product team and recommend that we implement this in the future.
While I don’t believe this is possible through the Query Metric Aggregates endpoint, I’m happy to look into this for you. Would you mind describing in a little more detail what you’re looking for, that our back in stock report doesn’t provide? You do have the ability to schedule a report to send to somebody each day, which should show you the number of products added and the SKUs of those products. Were you looking for the data to be presented in a different way, or for some data that our scheduled reports don’t have? I can reach out to our engineers to see what our options are!
