How can we use TaxJar with CraftCommerce? Is there anything akin to a presave event or postsave event where we can make a call to TaxJar API to get calculate and report sales tax? I find the integrated tax system impractical at the moment. I would like to create a plugin that can access the existing tax api platforms, but need to know the best insertion points for this.
The onBeforeSaveOrder event runs before all of the adjustments are calculated (including taxes), so it seems like that's what you're looking for.
