Hello,
I am google cloud certified cloud engineer.
so you want to add a subscription service and integrate the payment using the API.
Alright,
Is the website hosted using Google Cloud platform so we can use IAP and restrict the access ?
and we will maintain a db to keep a tack of it .
Subscribers will be able to view the map but will not be able to copy it or share it to others :
For this we need to implement the javascript level restriction to restrict the copy paste .
Looking forward to work with you and the product success.
Thanks
