Is there a good way to programmatically apply a discount to an order during checkout?

Spryker has to types of discounts:
• Cart rules: the discount will be applied automatically to the products based on set rules;
• Voucher codes: the discount will be applied to the products based on set rules and when a voucher is added.
Seems like cart rules is exactly what you want.
Here's the documentation on how to create discounts: https://docs.spryker.com/docs/pbc/all/discount-management/manage-in-the-back-office/create-discounts.html#prerequisites

yeah I'm looking at cart rules but I'm struggling to figure out how to apply them. We have loyalty cards (number only) that give you some discount, and the customer is not registered

U03T08LE3CP

maybe if I create something similar to this 🤔 https://docs.spryker.com/docs/pbc/all/discount-management/tutorials-and-howtos/howto-create-discounts-based-on-shipment.html#activate-a[…]nt-carrier

These plugins add more options to select in the discount configuration.

How does these loyalty cards work? Like voucher codes?

U03T08LE3CP

well kinda. If you have one you are entitled to some discount and the number is always the same

U03T08LE3CP

(same per user that is)

U01K43ADW5N

So it's a voucher code with unlimited uses?

U03T08LE3CP

yes

U03T08LE3CP

and hundreds of thousands of valid numbers

U01K43ADW5N

And how are you currently storing these loyalty codes?

It's sounding like you are going to have to create new decision rules

U03T08LE3CP

the codes are in a separate system

U03T08LE3CP

I can ask it if the code is valid

U03T08LE3CP

the codes are personal and I can also validate that it's with the correct person

U03T08LE3CP

all I need for Spryker is to say "ok this ruleset is now valid" after that

U01K43ADW5N

Yeah, exactly. You are going to need to create a new decision rule plugin.

the decision rule plugin implements the method isSatisfiedBy($quoteTransfer, $itemTransfer, $clauseTransfer): bool

U01K43ADW5N

You just need to check how are you going to implement the form where the user will add the loyalty code

U03T08LE3CP

we have a custom frontend

U03T08LE3CP

so I suppose it comes from somewhere(tm) through the Glue API 😅

Maybe you can also think of implementing this loyalty code as a Payment option, like the spryker's Gift Codes.

In our project we've implemented a loyalty points program and it works almost exactly as gift codes.

I think the discount rule system sounds like the way to try at least first. Thanks!
