Microsoft Graph API Get SKu Subscription

Question

We are currently using the Microsoft Graph API to retrieve tenant SKU subscription license counts for our organization. We have encountered a challenge in distinguishing between paid and trial licenses from the data we receive. We are seeking your assistance to address this issue.

We kindly request guidance on how to retrieve a list of SKUs that correspond to free or trial licenses separately from the paid licenses using the Microsoft Graph API. Any insights, examples, or best practices you can provide would be greatly appreciated.

Your expertise in this matter would greatly assist us in optimizing our usage of the Microsoft Graph API. Thank you in advance for your support.
