How to add webhook for creation of product categories
-
I’ve added a webhook via the UI for an ‘Action’ with action event: ‘woocommerce_api_create_product_category’
I would expect the webhook to be called when I create a category via api, but the webhook is not triggered.
I cannot find any documentation on valid values for the ‘Action event’ field, but I noticed that when the action event does not exist, it will not be saved and gives the message: Webhook topic unknown. Please select a valid topic.
The webhook does trigger the url when I register the webhook freshly, but no triggers after that.
If you need more info from me please let me know.

So after alot of trial and error, I figured out that the actual action event that I needed to use was ‘woocommerce_rest_insert_product_cat’
If anyone wants to add their own webhook, you should check out the controllers in {wpRoot}/wp-content/plugins/woocommerce/includes/rest-api/Controllers/Version3/*
Take the controller where the action is performed and check its $taxonomy variable in the class definition. If you cannot find it, it is probable defined in one of the extended classes(v2 or v1). For me it was in the ‘class-wc-rest-product-categories-v1-controller.php’ file.The hook will be called: “woocommerce_rest_insert_{$taxonomy}”
You can find all the different hooks in ‘class-wc-rest-terms-controller.php’, for instance ‘woocommerce_rest_delete_product_cat’ is also a valid action to hook onto.I hope it helps anyone who has the issue in the future.
