[12.x] Add withPromotionCode method

[driesvints]

This adds a withPromotionCode method to the subscription builder in addition to the withCoupon method in order to provide for Stripe's new promotion codes. When using this method, the API ID for the promotion code needs to be passed, not the promotion code itself.

$subscription = Auth::user()->newSubscription('default', 'price_xxx')
    ->withPromotionCode('promo_xxx')
    ->create($paymentMethod);

how can we retrieve the promotion code using promo code?

[driesvints]

@Naveedali1234 I don't understand your question, can you explain a bit more thoroughly?

[Naveedali1234]

okay let me explain it.

i am trying to verify promotion code if it exist in stripe dashboard or not. so when a user enter a promo code in text box for example: 7OIzSX3E

now i will need to retrieve this promo code from stripe dashboard if it exist or not, so i fetch it in this way: $promotion_code = \Stripe\PromotionCode::retrieve($request_input('promo_code'), []);

but this input is only the code and this input needs ID of the promotion code.

How can i achieve it?

i am sorry if i am asking something different, but i am just trying to fetch the response of it.

You can use the Stripe API like you posted above. I myself would just hardcode a list of promotion codes and their ids in the app itself. If you need something more dynamic, use the Stripe API.

Hey there @driesvints .

Couldn't we use a promo code as well when swaping subscriptions?

$user->subscription('default', $newPriceId)
   ->withPromotionCode($code)
   ->swapAndInvoice($newPriceId);

This doesn't work. From what I've been able to check, it only works in newSubscriptions.
Shouldn't it also work with swaps or am I thinking wrong?

Thanks
