Add a new functionality on an Odoo-Prestashop Connector

Hello
We are using an Odoo-prestashop connector for odoo 12 and prestashop 1.7.
This connector allowed us to connect our odoo instance to 8 different prestashop websites.
And we would like to add the functionality of updating the order status bi-directionally and if the delivery slip is done with a carrier tracking number, the tracking number must be sent to prestashop Immediately.
