Hi. generally speaking Checkout is a convenience way to integrate with Stripe, but it has some limitation on its own. You would want to integrate yourself if you want more control over small options here and there

#

And about the legacy code, yes Charge is an old API, and we recommend to use PaymentIntent instead nowsaday

echo laurel Sep 28, 2021, 8:54 AM

#

i'm just feeling overwhelmed by the amount of options available

#

seems like Checkout would take a huge burden off my dev shoulders

abstract aurora Sep 28, 2021, 8:57 AM

#

It depends on what you would like to achieve. Normally using Checkout is easier than building by yourself

echo laurel Sep 28, 2021, 8:59 AM

#

for example, we have a backend function that calculates discounts after the user inputs a discount code. these discounts are implemented by our backend, not on stripe. would we be able to dynamically change the price being charged by Checkout?

abstract aurora Sep 28, 2021, 9:01 AM

#

Have you considered to map your discounts logic to Stripe's Coupon or promotion code?

#

Or do you prefer to not using our Coupon and Promotion Code object?

echo laurel Sep 28, 2021, 9:02 AM

#

good question

#

dealing with legacy code is no fun 😄

#

to answer your question, i haven't

abstract aurora Sep 28, 2021, 9:03 AM

#

With a Stripe's Coupon, you can attach it to Stripe Checkout

#

we automatically manage the logic for you

echo laurel Sep 28, 2021, 9:04 AM

#

right

#

i'm trying to build something new without changing too much of the current system

#

so i'd like to integrate what we have with Checkout

#

not completely sure of the implications of completely rebuilding our discounts api

#

regarding current and old customers, old database data, etc

abstract aurora Sep 28, 2021, 9:07 AM

#

okie, then what data outcome that your discount api is providing?

#

like, what data structure?

echo laurel Sep 28, 2021, 9:08 AM

#

input: plan id, discount code
output: price after discount

abstract aurora Sep 28, 2021, 9:09 AM

#

Is it an one-time discount?

echo laurel Sep 28, 2021, 9:09 AM

#

hmmm, good question, i think not

#

multiple users can apply the code to their order

#

not sure i understood your question correctly

#

can you clarify please?

#

if you're referring to subscriptions, the discount applies to first payment only

abstract aurora Sep 28, 2021, 9:11 AM

#

I think that sounds like a Promotion Code more than a Discount

#

yeah

#

I am just imaging, passing the output of price after discount to the Checkout Session should work, no?

echo laurel Sep 28, 2021, 9:12 AM

#

we have fixed amount discounts, % discounts

#

the users inputs the code and we calculate the final price in the backend

#

and return to frontend

echo laurel Sep 28, 2021, 9:13 AM

#

abstract aurora I am just imaging, passing the output of price after discount to the Checkout Se...

that's what i'd like to know, if that's something that Checkout supports

abstract aurora Sep 28, 2021, 9:13 AM

#

yeah after calculate the final price in the backend, you create a Stripe CheckoutSession with that price. Is that working?

echo laurel Sep 28, 2021, 9:13 AM

#

like this interaction with the server side before hitting "pay"

abstract aurora Sep 28, 2021, 9:13 AM

#

ah

echo laurel Sep 28, 2021, 9:13 AM

#

not sure we're on the same page

abstract aurora Sep 28, 2021, 9:14 AM

#

you want the user to see the Checkout page

#

and input the code

#

intercept it and manipulate the final price

echo laurel Sep 28, 2021, 9:14 AM

#

user selects a plan and wants to pay for it, and has a code for a discount

#

there needs to be an input where to insert said code

#

and after inserting the code the price should be updated

narrow flicker Sep 28, 2021, 9:15 AM

#

then you want promotion codes!

echo laurel Sep 28, 2021, 9:15 AM

#

then hit submit and proceed with checkout

#

with whatever payment method the client wants

narrow flicker Sep 28, 2021, 9:15 AM

#

https://stripe.com/docs/billing/subscriptions/discounts/codes

echo laurel Sep 28, 2021, 9:15 AM

#

my issue is we have built and entire system to generate discounts

abstract aurora Sep 28, 2021, 9:15 AM

#

yeah

echo laurel Sep 28, 2021, 9:15 AM

#

it's our legacy code, my colleague built it

#

can we integrate that with Stripe Checkout

#

?

abstract aurora Sep 28, 2021, 9:16 AM

#

the problem is, you want to control over the promotion configuration

echo laurel Sep 28, 2021, 9:16 AM

#

i know, it's a nightmare situation

#

not pleased with it myself

#

not sure if i made my point across

#

the user would input the code to calculate the price he needs to pay, and only then proceed to checkout

abstract aurora Sep 28, 2021, 9:19 AM

#

How many patterns of final price that your system can output?

echo laurel Sep 28, 2021, 9:19 AM

#

i'm sure we can tell checkout how much to charge

#

i think we have at least 2, % and number

abstract aurora Sep 28, 2021, 9:21 AM

#

It's very similar to Stripe's Coupon then

echo laurel Sep 28, 2021, 9:21 AM

#

wait, what do you mean patters of final price?

#

patterns*

abstract aurora Sep 28, 2021, 9:22 AM

#

sorry, patterns of discount

echo laurel Sep 28, 2021, 9:22 AM

#

orakaro, i understand that Stripe does all this. but we don't want to completely redo our system

#

i didn't build the current system

abstract aurora Sep 28, 2021, 9:22 AM

#

yes, I mean, you can try to map from output of your system, to Stripe's Coupon

#

Let's say you have a set of code pre-generated, that your customer can input, correct?

#

You can map them to a set of Stripe'Coupon/Promotion Code

echo laurel Sep 28, 2021, 9:24 AM

#

our discounts are dynamically generated

abstract aurora Sep 28, 2021, 9:26 AM

#

Plan Id + Code -> Discount Pattern, correct?

#

What is this plan id? Is it the same for customers?

echo laurel Sep 28, 2021, 9:28 AM

#

we sell SaaS, we have 3 major plans, each one has monthly/yearly payment options, so total of 6 plans

#

each plan has an id

abstract aurora Sep 28, 2021, 9:29 AM

#

Can you simplify the call to your system to (Code) -> (Discount Pattern) ?

#

like, will different Plan Ids affect the output Pattern, within a same Code?

#

Okie, let say you can't. To put thing simple, I assume that you have 6 plans, and 10 pre-generated code

#

With each code, running with 6 plans, you should have 6 final prices. The question is, are those 6 final prices relative to the original prices with a fix percent or amount off?

#

If the answer is YES, you can create a Stripe Promotion Code, and map each of your code to a Stripe Promotion Code, then use Checkout

#

if the answer is NO, then you can't use Checkout. You would need to build the UI yourself, dynamically call you legacy system to define the final price

echo laurel Sep 28, 2021, 9:43 AM

#

there are 6 final prices, but for some reason we're generating different codes mapped to the same repetitive discounts

#

probably for referrals

#

so one code can only be used once

#

ok, no, we can have an infinity of discounts

#

so an infinity of final prices

abstract aurora Sep 28, 2021, 9:46 AM

#

with same code, 6 plans, still infinity of final prices?

#

I see

echo laurel Sep 28, 2021, 9:47 AM

#

yeah

#

no

#

let's see

#

we have 6 plans, each one with a different initial price

#

then we have an infinity of codes which produce different final prices when applied to initial price

#

that's all

abstract aurora Sep 28, 2021, 9:49 AM

#

I know that sense of infinity, but it's infinity of codes. Let's say you have 100, or 1000, it's all predefined, correct?

echo laurel Sep 28, 2021, 9:49 AM

#

more can be generated

abstract aurora Sep 28, 2021, 9:49 AM

#

yes

#

the point is, if for each code, result in a same pattern to all 6 plan with 6 different price, then you can sort of map 1:1, from one of your code to one Stripe Promotion Code

#

then no matter how many code you can generate, infinity, you can generate the same amount of Stripe Promotion Code

#

programmatically

#

but problem is, do we have the map 1:1 or not?

echo laurel Sep 28, 2021, 9:52 AM

#

when you say map, what do you mean exactly?

abstract aurora Sep 28, 2021, 9:52 AM

#

yes

echo laurel Sep 28, 2021, 9:52 AM

#

because in my mind i'm talking about an ajax call to the server before hitting checkout

#

with the plan id and discount code, to get the final price

abstract aurora Sep 28, 2021, 9:53 AM

#

I got that flow. I am suggesting before all of that, you can predefine Stripe Promotion Code based on all of your possible code, and let your customer use that instead of that flow

#

But if you think it's complicated and not worth the effort, just go with the direction of building your own checkout

echo laurel Sep 28, 2021, 9:54 AM

#

it's not that i think it's complicated, i just haven't understood what you mean 🙂

#

you mean when an admin creates a new discount using our system, at the same time we create a stripe promotion code which the user can apply using native stripe Checkout feature?

abstract aurora Sep 28, 2021, 9:56 AM

#

yes

echo laurel Sep 28, 2021, 9:56 AM

#

i see, i was missing that part

abstract aurora Sep 28, 2021, 9:56 AM

#

with the condition, that you can figure it out the discount pattern for each of your new discount, across all plan

echo laurel Sep 28, 2021, 9:57 AM

#

i see

#

what a horrible system haha

#

have discounts on 2 platforms

#

but i understand your solution

#

not your fault we've this legacy code to deal with

abstract aurora Sep 28, 2021, 9:59 AM

#

Only if the map is possible. If with a random_code an admin created, it resulted in 20% off for one plan but 30% off for another plan, then it's impossible

echo laurel Sep 28, 2021, 10:02 AM

#

map is possible

#

but for codes created before we did this, it wouldn't work

#

or we'd have to go back and create promotion codes for those

#

not fun

abstract aurora Sep 28, 2021, 10:03 AM

#

like a batch, but yeah depends on your system

#

Just go for custom checkout flow, in that case

#

Hi @echo laurel I need to run. Hope this gave you some material to decide. Feel free to come chat with other Stripe ppl if you have other questions!

echo laurel Sep 28, 2021, 10:05 AM

#

cheers orakaro, you were awesome

#

great job, thank you

abstract aurora Sep 28, 2021, 10:05 AM

#

good luck!
