How to sync multiple CRMs?

Question

CRM

Can't think of a solution

The firm uses several CRMs:

• amoCRM
  
• flowlu
  

How is it possible to synchronize them? So that when adding or changing data in one CRM, this data is also changed or added to another CRM.
I am writing in Python

So far, only this option is presented:
A database has been created and the program constantly receives data via API from one CRM and another CRM.
When changing in one of them, it introduces them into the other.

If you order freelance writing of such a system, what is the estimated price for it?
