Hmmm, I'm not sure. Let me check

Thank you, this is for a referral system, when a customer refers another user in our platform we add credit to the customer. When said credit is used we need to remove it from our local DB entries also - so need to identify when and how much credit has been used exactly whenever a succeeded invoice comes through
crystal verge
Ok, you'd actually look at total (which is the invoice amount pre balance) and amount_due
Balance isn't applied as a payment, it's more of a discount
wintry loom
so (total - amount_due) = balance used?
crystal verge
Yes, but be wary that other factors can influence the amount_due too (discounts/coupons, etc)
wintry loom
coupons are discounts no? So apart from checking for coupons is there anything else to take into account?
crystal verge
Well a Coupon transforms into a discount which are in the discounts field
crystal verge
coupons are discounts no? So apart from checking for coupons is there anything e...
I don't think so no

And there is absolutely no other property to check the amount of balance used? You always need to manually calculate this?
(or a different object?)
crystal verge
Well there'd be a customer.updated event that would fire on invoice payment to reflect the balance changing
wintry loom
that might be a cleaner way than checking on invoice succeeded for my use case? do you have any thoughts
crystal verge
Only issue would be mapping/tying the events together
wintry loom
I'm not sure I would need to do so? I just need to remove a balance entry in our database connected to the customer ID
crystal verge
Sure, that would work then
wintry loom
its something I will have to test, but customer.updated gives me another avenue to test
do you know off the top of your head if that event will give previous balance - current balance?
crystal verge
It'd have a balance field that would reflect the new balance post invoice payment. But then you can use previous_attributes[balance] to calculate a diff
i.e. If I applied all $100 of my balance to an invoice, balance: 0 and previous_attributes[balance]: -1000
wintry loom
-10000 (in cents) I assume?
crystal verge
Yes
