Hello! You should be able to create negative Invoice Items: https://stripe.com/docs/api/invoiceitems/create#create_invoiceitem-amount

spare flax Jan 20, 2022, 5:49 PM

#

Yes, I can. However, I'm trying to do it on the initial creation of the subscription, so the first invoice.

severe basin Jan 20, 2022, 5:49 PM

#

Can you give me the request ID showing the error you're getting? Here's how you can find a request ID: https://support.stripe.com/questions/finding-the-id-for-an-api-request

spare flax Jan 20, 2022, 5:49 PM

#

Sure, one second

#

@severe basin req_XilkCFFSb1YeHK

severe basin Jan 20, 2022, 5:55 PM

#

Ah, gotcha. Yeah, unit_amount there must be positive as documented here: https://stripe.com/docs/api/subscriptions/create#create_subscription-add_invoice_items-price_data-unit_amount

#

Can you tell me more about what you're trying to do? Maybe I can recommend an alternative.

spare flax Jan 20, 2022, 5:56 PM

#

Yeah. I'm trying to basically add a discount line item to the first invoice when a subscription is created. I can't add the invoice item afterwards because the invoice is already finalized.

severe basin Jan 20, 2022, 5:58 PM

#

Have you tried using a coupon? https://stripe.com/docs/api/subscriptions/create#create_subscription-coupon

#

https://stripe.com/docs/api/coupons

spare flax Jan 20, 2022, 6:00 PM

#

I have. The issue with the coupons are that they apply every time - even with upgrades. I would need coupons to apply one time for the initial subscription creation and then when upgrading a subscription, it should not apply it again.

#

@severe basin Is there any alternative way to discount items when creating a subscription or am I out of luck?

severe basin Jan 20, 2022, 6:09 PM

#

You can set the duration of a Coupon to once. Does that not work as expected?

spare flax Jan 20, 2022, 6:09 PM

#

I've tried that before, but if I recall correctly that throws off the proration.

#

and charges the customer more than it should. It excludes the initial discount from the calculation.

severe basin Jan 20, 2022, 6:14 PM

#

Can you give me an example Subscription ID showing that behavior and explain the desired behavior of that Subscription?

spare flax Jan 20, 2022, 6:19 PM

#

@severe basin Sure. sub_1KK5D84WfFZQ6geYDKpvt22n If you look at the latest invoice, it's $10 where it should be $5

#

👋 I'm hopping in since @severe basin has to head out soon - let me take a look

spare flax Jan 20, 2022, 6:19 PM

#

Hello! Alright, thanks

novel storm Jan 20, 2022, 6:22 PM

#

Yeah so the issue here is that you have a Coupon w/ a duration of once, but you want the coupon to actually be applied to all updates until the first time it's renewed, correct?

spare flax Jan 20, 2022, 6:23 PM

#

Correct. But If I set it to repeating, then it's applied to each invoice in addition to the proration.

novel storm Jan 20, 2022, 6:24 PM

#

How long did you set it to repeating for? Just one month?

spare flax Jan 20, 2022, 6:24 PM

#

Yep

novel storm Jan 20, 2022, 6:25 PM

#

Do you have an example invoice where it did that?

spare flax Jan 20, 2022, 6:25 PM

#

in_1KK4xi4WfFZQ6geYU1c4HVhT

novel storm Jan 20, 2022, 6:29 PM

#

Yeah I see the issue - let me try and confirm something really quick on my end

spare flax Jan 20, 2022, 6:29 PM

#

Okay

novel storm Jan 20, 2022, 6:50 PM

#

Sorry it's taking a while - I'm seeing some odd behavior with the invoice you sent over and I"m trying to pinpoint what it is

novel storm Jan 20, 2022, 8:10 PM

#

@spare flax Do you mind emailing support@stripe.com and mentioning that you're talking to karbi on Discord? Your usage of proration_behavior: none + billing_cycle_anchor in your subscription creation request is causing odd future repercussions on the future prorations generated. We have to keep looking into it, and emailing us will be easiest way for us to get back in contact with you

#

With that being said, is there a specific reason you're using proration_behavior: none in your creation request?

spare flax Jan 20, 2022, 8:14 PM

#

Alright, will do that. And yeah, the reason for that is there are some cases where we need to create a subscription when there is no payment method set. iirc, Stripe throws an error when creating a subscription when there is no payment information set for the customer.

novel storm Jan 20, 2022, 8:18 PM

#

If that's the only reason you're setting proration_behavior: none then I'd suggest not doing that - you should only be using that if you don't want to be charging the customer for the time between the sub start date and the billing cycle anchor. Instead, you can use payment_behavior: default_incomplete to still create the subscription and not attempt charging/confirmation in the same call.

spare flax Jan 20, 2022, 8:32 PM

#

hmm.. okay, will try that.

novel storm Jan 20, 2022, 8:35 PM

#

yeah this will let you bypass the weird behavior you're seeing entirely

@spare flax have you emailed in yet?

spare flax Jan 20, 2022, 9:51 PM

#

muted garden <@!140584108286803968> have you emailed in yet?

Not yet. I've been testing what @novel storm suggested and that seems to be working for me.

muted garden Jan 20, 2022, 9:51 PM

ah nice!
