Hi there, checkout.session.completed event is fired when your customer has completed the checkout session, it doesn't necessary mean that the payment is succeeded.

I'd suggest you to listen to invoice.paid event instead

I would like to enable the subscription for the user once checkout has completed (regardless of the payment succeeding). Then on failure, I would like to disable it.

Then you'll run into issue that you just described.

#

My question is in case of the payment failing, how soon the invoice.payment_failed is sent to avoid the situation described above.

#

So you're telling me there is no reliable way of enabling subscriptions right after checkout? The integration guide gave me the impression it should be possible: https://stripe.com/docs/billing/subscriptions/build-subscriptions?ui=checkout#provision-and-monitor

Build a subscriptions integration

Create and manage subscriptions to accept recurring payments.

The problem here is that your system needs time to provision the subscription and unable to handle the invoice.payment_failed event which may occurs after checkout.session.completed, and that's why I suggest you to only provision subscription when invoice.paid event occurs, which is mutually inclusive with invoice.payment_failed.

#

The question is which is generally faster, my system only needs about +- 1 second to provision the subscription.

#

Another solution would be to check if the payment failed in the checkout session completed event itself, but it seems that's not really possible: https://stripe.com/docs/api/checkout/sessions/object#checkout_session_object-payment_status

Please refer to the best practices https://stripe.com/docs/webhooks/best-practices#event-ordering

Stripe does not guarantee delivery of events in the order in which they are generated.

#

I'd strongly suggest you to listen to invoice.paid so that you can avoid this problem, and don't need to spend extra effort to fix the problem.

#

Fair, although I don't think my customers will be happy if they have to wait for the subscription to become active.

#

Alternatively you can implement an event queue in your system, so that it can still process the invoice.payment_failed event after finishing the provision task.

Yeah, that's a good idea. Will probably end up doing that. Thanks for your time!
