Hi there

pseudo gazelle Jun 7, 2023, 4:49 PM

#

Hi, we're seeing requests come in 1 second apart for the same tenant success page, does Stripe Checkout do some sort of retry/back-off thing after payment success with a redirect URL?

#

My understanding of the redirect process is that you are only redirected to the success URL after successful payment, even if that is an async payment. So we should only be seeing 1 incoming request from Stripe, not 3

#

Hmm yeah I would expect only one as well

#

Can you give me the Checkout Session ID where you see this?

pseudo gazelle Jun 7, 2023, 4:52 PM

#

Yes, one minute

#

Thanks let me see what I can find from our side

#

Still looking into some things but can you clarify a bit on the above logs. This is you logging an incoming request to your success URL, correct?

pseudo gazelle Jun 7, 2023, 5:16 PM

#

Correct, separate requests

#

the 2nd one seems to be the only "correct/expected" one

empty yacht Jun 7, 2023, 5:17 PM

#

Okay and looks like in this case for the original redirect here the client's browser got a 404 response from you?

pseudo gazelle Jun 7, 2023, 5:17 PM

#

seems to be the case

empty yacht Jun 7, 2023, 5:18 PM

#

Thanks for clarifying

#

Are you seeing this consistently?

#

I'm wondering if the customer just refreshed here?

#

Overall I'm not seeing an indication of multiple redirects from our end.

#

it's strange that we couldn't identify a user from the session on the other 2, also the ip is different from all 3 requests

#

seeing it sporadically but sufficiently enough for it to be a more widespread issue

#

it's unlikely to be refreshed because we actually redirect to another page instantly after this

empty yacht Jun 7, 2023, 5:20 PM

#

Gotcha

#

Hmmm

pseudo gazelle Jun 7, 2023, 5:22 PM

#

also our pre-Stripe Checkout page, is a lengthy process where the customer designs a poster and we give a shipping estimate so 1 second per request wouldn't be enough time for completely different users to complete the process

empty yacht Jun 7, 2023, 5:23 PM

#

You don't happen to have the success query params in your logs do you?

pseudo gazelle Jun 7, 2023, 5:23 PM

#

Not in these logs no

empty yacht Jun 7, 2023, 5:24 PM

#

Got it

pseudo gazelle Jun 7, 2023, 5:24 PM

#

what were you thinking? is it possible the redirect could be without the checkout session id or something?

#

that's a scary thought

empty yacht Jun 7, 2023, 5:25 PM

#

Yeah just wanted to confirm it is the same full URL each time

#

Do you have other logs of this? Are there instances where the initial redirect is a 3xx and retries still occur?

#

Do you have any retry mechanisms on your side?

uneven marsh Jun 7, 2023, 5:27 PM

#

👋 also hopping in here - I'm curious, how are you identifying 'user' for each of these requests?

empty yacht Jun 7, 2023, 5:27 PM

#

Like if your success URL is hit but you can't load your data for a second

#

Gotta hop away so going to leave this to Karbi for further investigation. You are in good hands!

pseudo gazelle Jun 7, 2023, 5:27 PM

#

Thanks @empty yacht Hi @uneven marsh

#

User identification is based on session/auth data

uneven marsh Jun 7, 2023, 5:36 PM

#

and this is only happening with some of your checkout sessions, right? not all?

pseudo gazelle Jun 7, 2023, 5:39 PM

#

correct

#

i wonder if our load balancer is affecting this?

uneven marsh Jun 7, 2023, 5:45 PM

#

Hmm.... that's a possibility - I was semi-thinking along those lines where something on either your end or your customer's end is intercepting the request and causing it to happen more than once

uneven marsh Jun 7, 2023, 6:08 PM

#

I'm definitely only seeing us attempt to hit your success URL a single time, if that helps
