Hello Cybrosys,

Thank you very much for your answer.

The reason why I asked this question is because, we want to connect multiple other software systems, so the frequency of exchanging data between Odoo sh and our local server is relative high. Is this a reason to switch to Odoo on premise?

If I chose RESTful API to make a connection, what is the best way to make a connection to my local server (e.g. VPN)? 

Thank you!

Hi

Go through the following,

RESTful API and XML-RPC are two ways to communicate between Odoo and your local server. RESTful API is more modern and standardized, while XML-RPC is older but still functional. RESTful API is also easier to use and has more language and tooling support. It typically offers better performance than XML-RPC.

In most cases, RESTful API is the preferred choice for two-way communication. However, if you have existing infrastructure or specific requirements that necessitate XML-RPC, it can still be a viable option.

Here is a table that summarizes the key differences between RESTful API and XML-RPC:

The best choice for you will depend on your specific needs and requirements.

Hope it helps
