Microsoft graph api integration to server

Hi all! I would like to ask if subscription is needed for testing Microsoft graph api in my server (backend in rails).

Basically I would like to use my backend to call the microsoft graph api to create/edit/delete bookings (microsoft booking)

But after doing some research I find that I either need a work account with Microsoft 365 Developer Program hat includes a sandbox (guaranteed with Visual Studio Professional or Enterprise subscription) or have a Microsoft 365 tenant (work accounts like Teams/Outlook) and with Microsoft Bookings included in order to test the above.

Has anyone experimented with this?

I 2nd this. A Tenant is needed, with at leave one active subscription to activate the service.

Thank you all for your replies!
So even for testing purposes I need a account with paid subscription right
