Hi,
Goal: I would like to have a two-way synchronization between Joplin server and the ERP Odoo (https://odoo.com) which use python.
How may I code a "client" in python that will synchronize all the data with my custom Joplin server the same as other existing client (windows desktop, ios, mobile, etc).?
It certainly can be accessed, it's just that the API isn't documented. You need to either read the code or look at the network traffic between Joplin Server and the app to reverse engineer it.
