hello! i'm afraid i don't quite understand - do you mean you want to be informed when the subscription price is updated?
spare helm
Basically before charging customer during subscription renewal, i want to validate is there any price got changed for that particular subscription plan recently if so i want to charge that new amount instead of old amount..
mighty torrent
can you give an example of any price got changed for that particular subscription plan lately?
spare helm
For example user bought one premium plan and current price for that plan is 5USD... 2 months Later merchant decided to increase the price to 7USD.. This change already updated in the merchant db ... During the next billing cycle renewal before charging cuctomer i want to validate the invoice amount against this merchant db amount, if it different i need to charge this amount
mighty torrent
why not just schedule the update using Subscription Schedules? https://stripe.com/docs/billing/subscriptions/subscription-schedules
if you want to validate the invoice amount, you can listen for the invoice.created webhook
spare helm
When this event exactly will be triggered? before subscription renewal day?
mighty torrent
invoice.created will be triggered when the invoice itself is created i.e. on the subscription renewal day
if you want to validate before the subscription is renewed, you can listen for the invoice.upcoming event
spare helm
Also there invoice.upcoming event as well, which can be configured to trigger 3/5/7/15 days before renewal.. For example
yes.. that what i am thinkinh..

Hi @spare helm I'm taking over this thread
spare helm
for example if i configure this for 3 days before, then i can check any change in the amount.. if no change i will leave as it it.. so it start continue to charge customer as usual
incase if the amount is different, i want to inform the customer on the price change then i need to charge that amount after 10 days from this...
For this use case schedule subscription will suit..
sharp cosmos
@spare helm is your latest question related to subscription schedule?
spare helm
yes invoice.upcoming & subscription schedule
sharp cosmos
What's your exact question?
spare helm
Basically before charging customer during subscription renewal, i want to validate is there any price got changed for that particular subscription plan against my local db recently if so i want to charge that new amount instead of old amount..
so i am planning to use invoice.upcoming event 3 days before renewal... on this event i will check price change.. if there is a change i will notify customer on the price change and want to charge customer only after 10 days of this notification...
sharp cosmos
So basically you don't want to automatically charge the user, instead you'd like to programmatically charge the user when you think the time is right?
spare helm
when the price is changed i need to charge new price... Even automatically also fine, just need to charge new price
sharp cosmos
Hmm, I don't understand what you mean by when the price is changed i need to charge new price ?
spare helm
For example user bought one premium plan and current price for that plan is 5USD... 2 months Later merchant decided to increase the price to 7USD.. This change already updated in the merchant db ... During the next billing cycle renewal before charging cuctomer i want to validate the invoice amount against this merchant db amount, if it different i need to charge this amount
sharp cosmos
You can't change the unit_amount of a existing price object, so this use case doesn't exist.
I think what you want is upgrading/downgrading an existing subscription with a new price, and you can learn more from this doc (https://stripe.com/docs/billing/subscriptions/upgrade-downgrade)
spare helm
Yes i was seeing that option only.. But is there a option to reflect the new price changes after 10 days like that?
This will update the subscription with new price immediately,
stripe.subscriptions.update('sub_49ty4767H20z6a', {
cancel_at_period_end: false,
proration_behavior: 'create_prorations',
items: [{
id: subscription.items.data[0].id,
price: 'price_CBb6IXqvTLXp3f',
}]
});
But i want to activate this only after some days, so that in the mean time i will inform the customer and all
sharp cosmos
You can use subscription schedule to automate it.
https://stripe.com/docs/billing/subscriptions/subscription-schedules/use-cases#upgrading-subscriptions I think this is the use case that you are looking for.
spare helm
ok let me look.. Now i want to confirm for this subscription price got changed or not... for that i can listen for invoice.upcoming right?
so with this event i will get existing plan price and compare with my local db to identify the price change..
But it looks like this event won't trigger for Daily plan
sharp cosmos
You should listen to customer.subscription.updated (https://stripe.com/docs/api/events/types?lang=node#event_types-customer.subscription.updated) to get notified whenever a subscription changes (e.g., switching from one plan to another)
spare helm
Ok when i go with subscription scheduling for the existing subscription, first i need to create schedule for the existing subscription, then have to update?
Actually i am trying to create sub schedule for the existing subscription to apply new price after some time.. it throws i can not set both subscription & start_Date
sharp cosmos
Can you share with me the request ID?
spare helm
I am trying in postman -
in my case right, i already have subscription.. If there is price change i will create priceID and have to create subscription schedule for the existing subscription to apply the new price id from the start_date (after some days)
sharp cosmos
OK, you should just use from_subscription param to create a subscription schedule first, and later update this subscription schedule with phases.
spare helm
yes, after that also i couldn't update the start date
sharp cosmos
You can't update the start date because you care creating a schedule from an existing subscription, which is already started
spare helm
yes for example i have subscription which end in 3 days... in the schedule that was given in end_date and start_date actual start date of that plan... Now i need to update the new price after 10 days right... As i can not modify start_date, what i can do?
sharp cosmos
You should update the subscription with an additional phase for the new plan, and you don't need to specify the start_date for the new phase if you already have the end_state for the 1st phase.
When updating a subscription schedule, remember to include all phases (current and new ones) in the phases array.
spare helm
Sorry to ask too many question... If i don't provide the start_date for my new phase, then it will take the end_date of current phase fas start_date.. But i don't want right.. May be my current phase end_date after 1 month, but i want to apply this new price after 10 days itself or vice-versa
sharp cosmos
Don't worry about the questions.
Just want to correctly understand the requirement, so you want to start the new phase one month after the end_date of the existing subscription ?
spare helm
just after the 10 days of price change.. irrespective of currentphase end_date
Seems i could able to update the current_phase end_date..
sharp cosmos
Yes, you've found the answer yourself
