hi there! yes, you can make it so a customers can update their subscription to pay $20 : https://stripe.com/docs/api/subscriptions/update. You would have to update the subscription.items / subscription.items.price_data https://stripe.com/docs/api/subscriptions/update

You won't be able to update an existing Price which already has active subscriptions on it. So it won't affect your existing subscriptions

when i update the subscription.items.price_data, i will have to create a new price and pass it to the /subscriptions/update, correct?

if you update it using subscription.items.price_data - it will automatically create a new Price

i generally don't recommend this though, cause you're going to end up with a new Price everytime someone creates a new subscription

you should create a new Price before hand, then update subscription.items.price with the Price

got it

you might want to look into using the customer portal : https://stripe.com/docs/billing/subscriptions/integrating-customer-portal

now you mentioned that existing subscriptions won't be affected - what if i want those that were already existing subscribed at $10, to be automatically put on the new subscription price to be charged the $20 after someone updates their subscription price?

[opaque kindle]

to clarify, do you want to update all subscriptions on that old price?

[faint ginkgo]

yes

[opaque kindle]

you'll need to loop through all existing subscriptions and update them to that new price. there's no automatic way / feature to do this currently

[faint ginkgo]

i see - so i would i have to create a background process to do that

[opaque kindle]

yep
