Hey there 👋 so it sounds like you're updating a plan and trying to figure out how to handle 3DS flows when you do. Does your flow have your user updating the plan through a UI, or will it be your system doing this behind the scenes?

Through the UI

#

Current action order is:

customer chooses the plan
api request to the back
we're trying to charge pro-ration, and in case of failure - declining plan update (there's an error thrown from Stripe API, that payment isn't verified)

So you'll want to see if the payment intent goes into a requires_action state, if it does then you'll want to look at next_action to see if it's redirect_to_url. Then you'll want to redirect the user, this discussed a bit further here:

If we're using subscription.update call with prorate option set

Where the payment intent can be got?

#

If you retrieve the subscription, you can expand the latest_invoice field to see the payment intent. You can also recursively expand the payment_intentto retrieve it's details in the same call.

#

E.g. before updating subscription plan - we should get latest paid invoice from that subscription, and verify it's payment intent?

#

Or it should be done after subscription update returned an error already?

#

You're wanting to check if the payment fails when you update the subscription, right?

sick gulch Nov 17, 2021, 2:07 PM

#

I want to make subscription upgradable for any card
So if error occurs - handle / verify or prevent it by verifying before

#

Sorry, my thoughts were getting a little off track. You'll want to do the upgrade, and then check the most recent payment intent.

sick gulch Nov 17, 2021, 2:12 PM

#

Can I generate a PaymentIntent before the subscription update somehow?

#

E.g. if I'd know the final amount of payment - can I create PaymentIntent, verify it, and then pass to subscription update call?

runic gazelle Nov 17, 2021, 2:16 PM

#

You could, if you determine the prorated amount and create a payment for it, and then update the subscription with proration disabled. But the payment you created won't be associated with the subscription in any way.
