The aim was to build a WordPress plugin to collect user data at the WooCommerce checkout and send this data to a selected CRM system. This was my first attempt at a WordPress plugin development and also involved how WooCommerce integrates with WordPress. A great learning experience.
The plugin was developed for a specific project and is not something that can be installed and used without modification.
Create a plugin template from various examples, and the WordPress documentation.
Add an admin Settings section to store the the required UID and URL for the CRM system.
Processing function to collect the Order information required, and send it to the CRM.
