Sure, seems expected if the payment was off-session. Any declines/3DS requests will transition the PI to requires_payment_method. You'd need to re-confirm the intent, providing payment details again. See: https://docs.stripe.com/payments/paymentintents/lifecycle

How PaymentIntents work

Learn how PaymentIntents work within the payment flow.

#

If the payment attempt fails (for example due to a decline), the PaymentIntent’s status returns to requires_payment_method so that the payment can be retried.

#

If you can provide a specific pi_xxx example then I can confirm

vocal abyss Mar 12, 2024, 9:07 AM

#

yes

#

Please tell me which API I need to use to check payment status. My case: using paymentIntent and 3DS, thanks

flint prism Mar 12, 2024, 9:09 AM

#

You'd look at the status field on the Payment Intent

#

Whether that's in a API request response payload or a payment_intent.* event, depends on your integration!

vocal abyss Mar 12, 2024, 9:12 AM

#

Yes, I know, but in case the 3DS fails or the card has problems, its status is required_payment_method -> This case is payment failure, right?

flint prism Mar 12, 2024, 9:13 AM

#

Did you read the doc I just shared above? Should explain it for you

vocal abyss Mar 12, 2024, 9:14 AM

#

I read it.

flint prism Mar 12, 2024, 9:15 AM

#

Then you should have your answer

vocal abyss Mar 12, 2024, 9:15 AM

#

If status = required_payment_method, how do I retry the transaction?

flint prism Mar 12, 2024, 9:16 AM

#

You re-confirm the payment via confirmPaymentIntent with Stripe.js

vocal abyss Mar 12, 2024, 9:20 AM

#

If I do a retried, its status will be succeed or failed, right? Will the status no longer be requires_payment_method?

flint prism Mar 12, 2024, 9:22 AM

#

No, if it were to decline again it would remain in requires_payment_method

#

There is no 'failed' status for a Payment Intent

vocal abyss Mar 12, 2024, 9:24 AM

#

If my system does not perform a retry, how can we confirm that the transaction was unsuccessful?

#

I will describe my system to you as follows :

#

Before entering the card entry screen, I will create an API payment intent call, and I will create a pending transaction on our site.

flint prism Mar 12, 2024, 9:27 AM

#

You'd receive a payment_intent.payment_failed webhook event and the intent will transition to status: 'requires_payment_method'. There'd also be a last_payment_error field on the object: https://docs.stripe.com/api/payment_intents/object#payment_intent_object-last_payment_error

The PaymentIntent object | Stripe API Reference

Complete reference documentation for the Stripe API. Includes code snippets and examples for our Python, Java, PHP, Node.js, Go, Ruby, and .NET libraries.

#

This should all be easy enough for you to try in test mode with a card that will decline and/or require 3DS that you can fail

vocal abyss Mar 12, 2024, 9:27 AM

#

In the general card input screen, I will use the payment element to display the card input form.

#

After entering the card and submitting, the payment intent will be confirmed and we handle the following cases:
If the confirmed payment intent return status is success, we will update the transaction on our system as completed
If the confirm payment intent returns a status of canceled, we will update the transaction on our system as failed
If the confirm payment intent returns a failed status, we will update the transaction on our system as failed
If confirm payment intent returns status as requires_payment_method and last_payment_error exists, we will update the transaction on our system as failed

#

Could you please advise me on whether this plan is good for us?

flint prism Mar 12, 2024, 9:29 AM

#

If the confirm payment intent returns a status of canceled, we will update the transaction on our system as failed
This will only happen if you explicitly cancel the intent or it 'expires' in a auth/capture scenario

#

If the confirm payment intent returns a failed status, we will update the transaction on our system as failed
There is no 'failed' status, as I've explained

#

In any case, you should be using webhook to determine payment outcomes: https://docs.stripe.com/payments/handling-payment-events

#

Is using weehook a must? We cannot use retrieve for testing.

#

After entering the card and submitting, the payment intent will be confirmed and we handle the following cases:
If the confirmed payment intent return status is success, we will update the transaction on our system as completed -> ok
If the confirm payment intent returns a status of canceled, we will update the transaction on our system as failed -> can happen
If the confirm payment intent returns a failed status, we will update the transaction on our system as failed -> no happen
Is it right?

flint prism Mar 12, 2024, 9:35 AM

#

It's not a must but it's highly recommended yes as ultimately there's no guarantee your users will be redirected to the return_url after completing the payment (like authenticating with their bank). If you have custom fulfilment logic that runs at the return_url then that may never be triggered

As I said, you should just test out these flows and see how they behave with the test cards. I'm answering the same questions over and over

vocal abyss Mar 12, 2024, 9:37 AM

#

switch (paymentIntent.status) {
case 'succeeded':
message.innerText = 'Success! Payment received.';
break;

case 'processing':
  message.innerText = "Payment processing. We'll update you when payment is received.";
  break;

case 'requires_payment_method':
  message.innerText = 'Payment failed. Please try another payment method.';
  // Redirect your user back to your payment page to attempt collecting
  // payment again
  break;

default:
  message.innerText = 'Something went wrong.';
  break;

}

#

Is this part handle error?

flint prism Mar 12, 2024, 9:39 AM

#

I don't understand the question

vocal abyss Mar 12, 2024, 9:40 AM

#

This part explains how the intent confirm may fail and how to handle that.

flint prism Mar 12, 2024, 9:41 AM

#

Sure, seems reasonable

#

Did you test it?

vocal abyss Mar 12, 2024, 9:48 AM

#

I code by php and vuejs

#

About BE, I create 2 API

#

1 API to create payment intent and create transaction in my side.

flint prism Mar 12, 2024, 9:50 AM

#

OK, I'm not sure what you're asking me to be honest

vocal abyss Mar 12, 2024, 9:50 AM

#

Should the confirm payment intent part be handled in BE or FE?

#

I need to ask about stripe integration in our system.

flint prism Mar 12, 2024, 9:51 AM

#

vocal abyss Mar 12, 2024, 9:52 AM

#

Yes, I am processing to confirm payment intent in FE

flint prism Mar 12, 2024, 9:52 AM

#

OK, then I don't understand what question or issue you have

vocal abyss Mar 12, 2024, 9:54 AM

#

After FE confirms the payment intent, what do we need to do next to update the transaction status in our system?

flint prism Mar 12, 2024, 9:55 AM

#

As I said, you should be handling any fulfilment/post-payment logic with a webhook
