Description

Feature request

  • Extension name: firestore-stripe-payments

Is your feature request related to a problem? Please describe.

I would like to create a way for my customers to automatically redeem a coupon intended only for a specific customer group. Currently you can only specify a promotion_code when creating a checkout session.

Describe the solution you'd like

It would be nice if in the future you could also pass a coupon parameter.

Stripe Api allows this via

discounts.coupon
optional
The ID of the coupon to apply to this Session.

Additional context

We could simply add coupon as a parameter and edit

if (promotion_code) {
      sessionCreateParams.discounts = [{ promotion_code }];
}

to

if (promotion_code || coupon) {
      sessionCreateParams.discounts = [{ promotion_code, coupon }];
}

to the createCheckoutSession function.

Contributor guide

Research direction
Add coupon parameter to createCheckoutSession function, updating the discounts array to include coupon alongside promotion code.
