Hey! Can you share an example event ID? evt_xxx

dry harness Dec 17, 2021, 9:56 AM

#

Hey!
here's the request ID req_LD7vawYYVUIwnF for my request to end the trial (before the trial_end date)

#

and here's the webhook event id:

2021-12-17 09:25:06   --> customer.subscription.trial_will_end [evt_1K7cgXBVFeaV0FZKzZBu9aXV]

#

Thanks, will take a look!

dry harness Dec 17, 2021, 9:59 AM

#

Many thanks @analog zodiac 😉

#

Hmm. Yeah, can see the trial_end is updated in your API call, but not reflected in that event

dry harness Dec 17, 2021, 10:08 AM

#

any idea why ?

#

I mean why customer.subscription.trial_will_end is fired out of that 3 days to trial_end range ?

#

I don't I'm afraid. My guess is that it's some kind of race condition – the event is fired before the actual Subscription object is updated. For example, this customer.subscription.updated event has the expected trial_end value: https://dashboard.stripe.com/test/events/evt_1K7cgYBVFeaV0FZKnxv2L18U

#

And it's sent at the same timestamp as the customer.subscription.trial_will_end (2021-12-17 09:25:05)

#

But we can't guarantee ordering: https://stripe.com/docs/webhooks/best-practices#event-ordering

Best practices for using webhooks

Implement these best practices when using webhooks.

#

So you probably need to code a little defensively in your webhook handler to prevent this

#

i get it, so maybe delaying like 2seconds, and asking back for that subscription state to see if active or trialing ?

#

That's one option I guess, seems a little expensive

#

Trying to think of another

dry harness Dec 17, 2021, 10:24 AM

#

is there a possible calculation between date to see if it's in that 3 days period

analog zodiac Dec 17, 2021, 10:25 AM

#

Yeah, I guess that would work

#

You can use the trial_end timestamp and compare it to Date.now()

#

And see if it's actually within the timeframe you want

dry harness Dec 17, 2021, 10:26 AM

#

yay this seems a better solution, thank you for your time 🙂

#

stripe timestamps are UTC ?

analog zodiac Dec 17, 2021, 10:30 AM

#

Yep!

dry harness Dec 17, 2021, 10:39 AM

#

implemented and tested, all good ! many thanks 👍
