Removes the subscription data parameter from the Create Checkout Session endpointBreaking changes

What’s new

Removes the subscription_data[coupon] parameter from the Create Checkout Session endpoint. Use the discounts parameter instead.

Impact

Lets you apply discounts to Checkout Sessions using the discounts parameter, instead of the previously available subscription_data[coupon] parameter. This provides a more generic way to handle discounts, rather than being limited to just coupons.
