Hi,
Are you looking for integrating this using FireBase:
https://stripe.com/docs/payments/checkout/free-trials

[brazen karma]

I am using your extention

ext-firestore-stripe-payments-createCheckoutSession

trial_period_days doesn't seem to be used anywhere

I am not sure if it's supported or not

[lucid light]

That parameter is not supported via that extension. You'd use trial_from_plan (https://github.com/stripe/stripe-firebase-extensions/blob/next/firestore-stripe-payments/functions/src/index.ts#L134) instead

Means you need to explicitly set the trial value on the associated price via the Dashboard:

I saw that option, but since it said Legacy i figured it might get deprecated

Any plans to change this to the new system?

[lucid light]

It may, but there's no plans and nothing like that would be removed without an API version

[lucid light]

No, because the client-side nature of the extension opens up trial abuse vectors (e.g. could create a Checkout Session with a 999 day trial)

[brazen karma]

Ok, so I need to setup the free trial for each price (i have many currencies) and then call the trial from plan = true when creating the checkout?

[lucid light]

There's various issues on the repo about this

[brazen karma]

is there a way to update prices using API so I can automate this?

[brazen karma]

A quick suggestion could be a metadata document in firestore or something that holds additional information such as trial

[lucid light]

Pretty sure that's a Dashboard only field

[brazen karma]

yeah, I don't find it in the docs

for API

😢
