WooCommerce

Order and shipping notifications, with no vendor in between.

What it does

The same order and shipping flows as Shopify, on the store you host yourself. Doc 6 calls this the friendliest auth story in the document, because there is no vendor at all: no app store, no review, no partner programme.

Connecting it

WooCommerce’s own key handshake — one click on your site produces a read-write key. Nothing to submit to anyone.

What to know before you rely on it

Your site has to be reachable
Publicly reachable over HTTPS, with pretty permalinks on, or the REST API is not there to talk to. WooCommerce 3.5 or newer.
Read-write, because creating a webhook is a write
We would prefer a read-only key and cannot have one. If that is not acceptable, the fallback is that you create the webhooks by hand and we hold a read key.
There is no abandoned-cart webhook in WooCommerce
Core WooCommerce does not emit one, so abandoned-cart flows on Woo work differently from the Shopify version. Saying so beats shipping a flow that never fires.
