Hmmm, I'm not sure why this is happening. Let me dig a bit more and get back to you

#

Thank you @crystal sable

#

maybe api version? using
2020-08-27

#

I don't think it's that, because we had support for proration_behavior on Subscriptions forever

#

Hmmm, it looks like from our docs:

cancel_at
A timestamp at which the subscription should cancel. If set to a date before the current period ends, this will cause a proration if prorations have been enabled using proration_behavior. If set during a future period, this will always cause a proration for that period.

#

I think that indicates prorations were expected in this case, even though proration_behavior was set to none

#

is there a way around this? Like do I need to turn proration off with one api call and then second network request to update the cancel_at

#

You would set cancel_at to match the end of the billing cycle

limpid bolt Jan 10, 2023, 11:41 PM

#

is there a way to set cancel_at to be at the end of the NEXT billing period?

#

or do you have to calculate that? if you have to calculate, then we could potentially be off by minutes,

balmy imp Jan 10, 2023, 11:43 PM

#

Sure, just as long as your timestamp has the correct value

limpid bolt Jan 10, 2023, 11:43 PM

#

and if we're off by minutes, then it gets prorated

balmy imp Jan 10, 2023, 11:43 PM

#

Yes that is true

#

Situations like this are one of the use cases we developed Subscription Schedules for, where you can set the Subscription to cancel after a specified number of billing cycles. https://stripe.com/docs/billing/subscriptions/subscription-schedules/use-cases#installment-plans

okay got it. is there a way to modify an existing subscription (without a subscription schedule) to give it a subscription schedule?

balmy imp Jan 10, 2023, 11:58 PM

#

Sure, you can create the Schedule from an existing Subscription. https://stripe.com/docs/api/subscription_schedules/create#create_subscription_schedule-from_subscription

I would highly recommend you test this out though. Subscriptions can get complicated and Schedules adds another layer to it.

#

Another complicated but powerful tool for just this scenario is Test Clocks: https://stripe.com/docs/billing/testing/test-clocks
which let you simulate time advancing on your Subscriptions.
