We have a custom app for our store that sends customers email updates on their orders (for example, backorder status updates). Since the emails are sent through the app rather than through Shopify, the emails don’t show up in the order timeline, so there’s no way for our staff to confirm that we contacted each customer. We would like to make the following feature request: enable the Shopify “contact customer” notification to be sent from an order via the API.
Alternatively, if timeline events could be opened up to custom apps, that would be super helpful too.
Thanks!
