This is chapter 5 of 5 in the series Getting to Know Woo: A Series on the Cart and Checkout Blocks
In the previous posts, we’ve looked at extensibility on the front end side, focusing on adding new content, modifying existing content, and extending payment methods. However, you may sometimes need to modify behavior on the server side. In this final post of the series, we will look at action and filter hooks available in the Cart and Checkout blocks.
Extensibility on the Server Side (Hooks)
There are also some PHP action and filter hooks provided for extending various aspects of checkout behavior on the server. Keep in mind that it’s generally preferable to use extension interfaces like the IntegrationRegistry instead of actions and filters, as they provide a more stable way to integrate. However, these actions and filters still allow for some more flexibility in complex integrations.
