Hi everyone, 

I am new here and working on the task which I am adding customer data to Odoo res.partner model through python using API. 

My question is: Is there any ways or tip that I can use to get the last update date, max_id or something like this? 

My data will be continuously added and I do not want duplicate records. So, I want to have one parameter which I can use to get the last added customer and start to create/update customers from that time on.

So if the same customer is existing: update the data

If not: create a new one
