Hi Ebrahim,
Microsoft Flow is a public cloud service only. However, you can securely connect to your own on-premises services through the on-premises data gateway.
You can connect to services on your local network using the on-premises data gateway.
You can also check FAQ’s about Flow: https://docs.microsoft.com/en-us/flow/frequently-asked-questions
Since your query is related to Flow, I’ll suggest you create a new thread in Microsoft Flow Community if you need further help. If you have any issue related to SharePoint 2013 On-Prem, please create the thread in SharePoint 2013 On-Premises forum
Your understanding is highly appreciated.
Regards,
Neha
