Hi,

I have an Angular 7 application and want to add a billing plan. I have more questions. Thx a lot.

Is it possible to https://www.paypalobjects.com/api/checkout.js for that?

Would it be a security issue if I directly call the API from client (since no SDK available)?

Is it more work to call directly the API instead of using firebase functions with the SDK? As far as I understood it is just 3 calls, create billing plan, update billing plan and create billing agreement.

Do I need to create a billing plan all the time a customer wants to subscribe or is 1 enough (all customers get the same plan) and just make the billing agreement? If so can I use the checkout.js for only the agreement and create the billing plan manually?

Thx a lot, Nikolaus
