Hi there ??
This is a fairly complex development topic. I’m going to leave it open for a bit to see if anyone is able to chime in to help you out.
In case that you have missed it, you can see all of the Hooks and actions available within WooCommerce here:
https://woocommerce.github.io/code-reference/hooks/hooks.html
I can also recommend the WooCommerce Developer Resources Portal for resources on developing for WooCommerce.
You can also visit the WooCommerce Facebook group or the #developers
channel of the WooCommerce Community Slack. We’re lucky to have a great community of open-source developers for WooCommerce, and many of our developers hang out there, as well.
Cheers!
