In cases where there is no initial payment (i.e. free trial, 100% discount) then we won't generate a Payment Intent – you can't have a zero-amount Payment Intent.

Ok, but why there is no client secret for 99.9 discount

[mystic moss]

Instead, you'd confirm the pending_setup_intent field on the Subscription: https://stripe.com/docs/api/subscriptions/object#subscription_object-pending_setup_intent

[mystic moss]

Depends on what the actual discount amount it. We have minimum charge amounts. If the total is beneath that, then there's no payment and we'll debit the customer balance (to be paid on the next invoice)

[thin girder]

How big is that limit when payment intent will be generated ?

[mystic moss]

Depends on your settlement currency: https://stripe.com/docs/currencies#minimum-and-maximum-charge-amounts

[thin girder]

Oh, ok, thanks

[mystic moss]

In cases where there's no latest_invoice.payment_intent, you'd use the pending_setup_intent field as stated 👆

[thin girder]

Can this be used for confirmPayment on the front-end ?

https://stripe.com/docs/api/setup_intents/object#setup_intent_object-client_secret

I mean if there is a 100% discount we need to use setup intent client secret, right?

[mystic moss]

You'd use confirmSetup: https://stripe.com/docs/js/setup_intents/confirm_setup

[thin girder]

Oh

[mystic moss]

Correct yes. So you'd need logic to check the returned Subscription object after creation and see whether pending_setup_intent has a value. If it does, use that client_secret with confirmSetup

Otherwise use latest_invoice.payment_intent with confirmPayment

[thin girder]

Ok, one more question to clarify

Currently we are using confirm API where we check payment_intent

by its id

if its status == PaymentStatus.Succeeded we are confirming update and making changes to our db to change some restrictions

but if we use setupIntent, what changes should be done?

[mystic moss]

What do you mean by 'confirming update'?

[thin girder]

I mean we check that payment was succeed

Sorry for incorrectness

[mystic moss]

Is this for provisioning/fulfilment?

[thin girder]

I guess so, we are applying changes for payed subscription plan only if payment was succeed

[mystic moss]

General recommendation is to rely on invoice.paid for that: https://stripe.com/docs/billing/subscriptions/webhooks

That will account for both Setup Intent and Payment Intent scenarios
