👋 Hi there, Happy to help!
Could you please share more details about your issue ?

unreal holly Nov 17, 2022, 1:12 PM

#

Yes, I inserted a link there to our previous conversation in discord.

#

but okay, I will start over

#

What I would like to achieve is create a subscription for my customer that have a "paid trials" plan for a week, after a week it will start a monthly plan (with different price) for 1 product. and the customer will be charge automatically every month until they cancel the subscription

#

then the final flow that we agree is,

make a normal subscription
listen to invoice.paid event
then change the subscription plan

#

but I got an error in webhook logs.. <b>Fatal error</b>: Uncaught (Status 400) (Request req_Ldao9lkbFwGGjh) Changing plan intervals. There's no way to leave billing cycle unchanged.

#

if you need anymore details just let me know

glad burrow Nov 17, 2022, 1:31 PM

#

Yes checking ...

#

The error looks explicit,

Changing plan intervals. There's no way to leave billing cycle unchanged.
You can't change the plan and keeping billing_cycle_anchor: "unchanged"

#

You need to set billing_cycle_anchor: "now" or I may suggest you to use Stripe Subscription Schedule in order to achieve your scenario

#

but I try changing the subscription manually from dashboard, it works.

glad burrow Nov 17, 2022, 1:59 PM

#

The dashboard changes the billing cycle anchor

#

but when calling your api you're setting the billing_anchor unchanged

unreal holly Nov 17, 2022, 2:33 PM

#

ahhh, if so... what should I change it to so that it behave the same like the one from dashboard?

#

I'm not sure I follow -- if the interval changed the anchor must necessarily change. Are you sure you changed the interval? More complex flows would potentially need a schedule as @glad burrow noted.

unreal holly Nov 17, 2022, 3:12 PM

#

the interval should be changed, because the frist subscription is weekly then it updated to monthly

violet surge Nov 17, 2022, 3:13 PM

#

Sure, so the billing cycle anchor must change too. Do you have an example you updated?

unreal holly Nov 17, 2022, 3:18 PM

#

#

this is the one that I manually do in the dashboard

#

But if it's not possible. I can go with the subscription schedule api or any other route it's okay. Maybe can you walk me through the flow please

violet surge Nov 17, 2022, 3:22 PM

#

Can you share the subscription id? sub_1234 eg

unreal holly Nov 17, 2022, 3:22 PM

#

sub_1M57kVBBuNcFsmgMfTisZVdt

violet surge Nov 17, 2022, 3:28 PM

#

The billing cycle anchor did change when you made the dashboard update here: https://dashboard.stripe.com/test/logs/req_ThpyGYVGfkGkVQ

Stripe Login | Sign in to the Stripe Dashboard

#

the anchor moved from 1668690203 to 1668698218

#

I see, so I should use the subscription schedule API instead...

#

Can you show me the steps with the subscription schedule API please

elfin harbor Nov 17, 2022, 3:45 PM

#

Hi. have you read over https://stripe.com/docs/billing/subscriptions/subscription-schedules ?

Subscription Schedules API

Learn about the Subscription Schedules object and how to use it.

unreal holly Nov 17, 2022, 3:51 PM

#

yes, but I don't understand how the payment works for the schedule api.

#

is it the same like subscription API?

elfin harbor Nov 17, 2022, 3:52 PM

#

What don't you understand, specifically? Not sure I understand the question

unreal holly Nov 17, 2022, 3:55 PM

#

sorry, I mean.. for example... the flow for subscription api is :
create stripe elements, collect the data, pass the data to confirmPayments(), if it's success then redirect to thank you page.

but for schedule api, how is the flow?

elfin harbor Nov 17, 2022, 4:03 PM

#

Ah. Subscription schedules create subcsription objects, so it would essentially be the same. You can even create subscription schedules from existing subscriptions
