I believe it'll only trigger customer.subscription.updated if the subscription is also modified when you updated the schedule - so i you were updating the current phase that would probably trigger the event

okkk

#

I have an issue then

#

Imagine the following 2 processes:

We are doing this for a product that can be sold in instalments of 3 or 6 months.

The customer comes and pays the first instalments.

Watch new subscriptions created --> create Schedule subscription --> Modify the number of phases to 3.

We are looking for a way to measure automatically when he pays the second instalment. For this we have the following process:

Watch Subscription Events (customer.subscription.updated)

#

what seems to be happening is that whenever process 1 starts, it also triggers process 2. (I am trying to understand, how I could atleast filter out the triggers that I don't need .

Ah, let me clarify - a subscription that is on a schedule will still trigger customer.subscription.updated events. So when the subscription renews (for the second installment), that will still trigger a customer.subscription.updated event. If you only want to know about the specific event you want - you can check the billing start + end dates to make sure that the event was triggered because the subscription renewed

#

Does that make sense?

#

not really, what do you mean by: " you can check the billing start + end dates"

#

To be specific, if you only care about certain customer.subscription.updated events, you should check that only the attributes you care about were updated. So in this case, you only care that the subscription renewed - so you'd make sure that current_period_start and current_period_end were included in previous_attributes on the event

#

maybe I am a bit slow, but I don't really get it. why would I care about current_period_start and current_period_end.

#

let me research them a bit

#

Those are the dates of the current period, so they'd only be changed once a Subscription is renewed - since you only care about when a new "installment" has occured, that's the same as a new period occurring on a Subscription.

I see

#

Alternatively, you could check that a new invoice is being generated (since that will also coincide with when the subscription renews)

#

let me look into this a bit.

#

#

is it possible to tell me what was updated here?

bleak plover Jun 21, 2022, 4:24 PM

#

Yes, you want to look in previous_attributes on the event - you can see that includes cancel_at and canceled_at, so those are the two things that got updated

oblique ginkgo Jun 21, 2022, 4:27 PM

#

you guys have a very interesting way of dealing with subscription events

#

take this for example

#

evt_1LD9rgBUHziHdjOsjt2rU8P1

#

This is for a subscription that I just essentially created.

bleak plover Jun 21, 2022, 4:33 PM

#

Well all subscriptions start off as incomplete, but because you were able to pay it, it immediately transitioned to active

I'm going to archive this thread, but if you have any other questions feel free to ask
