Microsoft Graph: Are beta APIs bound to the release mode of Office 365?

Question

We plan to use some specific Microsoft Graph beta APIs to access data from Office 365. But our Office 365 tenant will be in standard release mode, NOT targeted release.

Is this compatible? Or is the general availability of Microsoft Graph beta/preview APIs somehow bound to the release mode of the tenant the data is being accessed of?

(Of course, when accessing data that can only be created in a targeted release tenant this data won't be available. But will the corresponding (beta) API be callable? Probably returning an error indicating this dicrepancy, or just nothing?)

I want to call beta APIs for standard and targeted release features without having the tenant in targeted release mode. To create a single code base for both release modes.

Answer 1

There isn't a correlation between the Microsoft Graph endpoints (/v1.0 and /beta) and your tenant's release mode.

Of course, if you attempt to exercise a method through the API that isn't applicable to your tenant then it will fail. For example, if you attempt to call /me/messages but your tenant doesn't have Exchange Online then it wouldn't be able to complete the request.
