Hi,
we developed a Model-Driven app and we have a requirement to incorporate some kind of "subscription" logic inside it, so when a customer deploys the solution to their environment in their tenant, then when a user tries to sign in to the app, the app sends a request to a subscription server/service, to check if a valid subscription is there or not, and accordingly the user will be granted access or not.
I am attaching here a flowchart describing the process, so we need the simplest way to achieve this.
appreciate any help and guidance on this.
Thanks
Mohammad
