Paypal recurring payment with variable amount first month

Question

First, notice I have read many post regarding this topic, but the info provided is not enough for me or is not accurate.

I´m developing a website with ASP.Net Core that offers different services. Users can subscribe to these services and they get a Paypal Recurring Payment to pay these services (using subscription API). For a fixed amount the service is working well for me.

Now thing is that i want to introduce a Discount system to user. When user apply some coupon code then some discount will be applicable only first month and rest of month user will pay full amount.

Suppose i have a service plan $200 per month. When a user purchase service and enter Coupon code XXXXXX then first month charges will be $150 and rest month $200 every month.

Suppose i have a service plan $200 per month. When a user purchase service and enter Coupon code YYYYYY then first month charges will be $130 and rest month $200 every month.

I have read many docs and but didn't find solution.

Answer 1

Coupons are your own business. Have the user enter their coupons, calculate what you want to charge, and then create a plan for what you want to charge.

You can show your coupon negative amount discounts in the plan text description so the user sees them during checkout, and feels good about paying less. But as far as actual amounts for payment processing, PayPal doesn't care about that; it just needs to know the actual amounts that are being charged at each moment.
