Hi there, what event are you listening to?
frozen spade
invoice.payment_succeeded
frozen warren
OK. So that's an invoice event, so you'll get the invoice object.
You should use the subscription of this invoice to retrieve the subscription object, from there you can find the price list from items (https://stripe.com/docs/api/subscriptions/object#subscription_object-items)
frozen spade
Why is the price a list? In what situation would a subscription have more than one item in the list?
frozen warren
You can add more than one price to a subscription.
frozen spade
Like the same tier having multiple prices? Or a single user's subscription having more prices as they moive up/down the tiers?
I'm just trying to understand... I know how subscriptions work for me as a consumer, not as a service/business
frozen warren
Stripe provide the flexibility to let user add multiiple prices in a subscription. You don't need to use it if your business doesn't require it.
https://stripe.com/docs/api/subscriptions/object#subscription_object-items-data-price-tiers So here's how you get the tiers info from price. remember to expand the tiers field.
https://stripe.com/docs/api/expanding_objects you can read here to learn more about response expansion.

So if the customer updates to a different plan, does that add a new price to the subscription list of items? Or does it just update the one single item in that list?
Another question. If I create a free tier, can I create a product with price zero? Then when a user registers on my website, I assign the free subscription by default. Would that incur any charges for me to pay?
frozen warren
It depends on how you update the subscription. You can change the price, quality, or add a new price (https://stripe.com/docs/billing/subscriptions/upgrade-downgrade)
What do you mean by free tier?
frozen spade
Well, my thinking is to create the user with a free plan, and redirect them to the stripe billing portal so they can manage their subscription. When they update their subscription, does it trigger an event I could listen for on my webhook?
I use tier as plan (or product) here.
and "free" basically means "no plan"
frozen warren
OK, so no plan = no subcritpion ?
frozen spade
they can't use my website, but can still come back in the future
no plan = subscription that costs $0
frozen warren
OK, yes you can create zero dollar subscription.
https://stripe.com/docs/billing/subscriptions/webhooks and these are the webhook events for subscriptions
