Hi,
At the moment the WooCommerce order object really only exposes the “most obvious” parameters such as order total, date and customer details. We are working on being able to expose more detailed data. But that adds a bit of complexity and we want to make sure we get it at least somewhat right. Short answer, we haven’t got that far yet.
But your use case sounds really interesting, understanding your needs may lead us in the right direction in terms of “getting it right”. If you’re up for sharing we’d be very happy if you want tell us more about it, send us an email at [email protected].
For an example of how to use the request body field in a REST API Call action, have a look at this blog post:
