Get plan prices and user limits
Listing available plans for your offer only returns you the Id and Name:
https://docs.microsoft.com/en-us/azure/marketplace/partner-center-portal/pc-saas-fulfillment-api-v2#list-available-plans
It would be useful to get (if is not a flat rate plan) the range of users (minimum and maximum) the plan is valid.
Also the price per user/month and user/year (if set) in the currency a parameter in the URL specifies:
https://marketplaceapi.microsoft.com/api/saas/subscriptions/<subscriptionId>/listAvailablePlans?api-version=<ApiVersion>&locale=en-US
