Considerations
Platform wide change, this should work on every market;
This should affect delivery orders only.
Identify Payment Methods as Online or Physical Payment
We should identify on both Frontend (WhitelabelApp) and in the backend (Payment Service). The main implementation and first barrier should be the frontend (hidding the Physical Payments from the payment methods dropdown). In other hand, the backend should grant that, even somehow the Frontend allow the Physical Payment, it will be blocked.
Frontend: Add onlinePayment at Payment Method Interface
Add a new property called onlinePayment at this interface
Update the constants that implement this interface adding the onlinePayment method here, the configuration should be:
...
Create a new method to verify if a payment type is online or not. This method should grant that cash will always be considered false regardless the configuration. (as you can see, there’s no configuration for cash in the table above, that represents the state/payment/constats.ts file)
Creating Editable Configurations
Note |
---|
Alternative check sanity payment method sort feature, having this map in LD or Sanity we can retrieve in the backend to add extra layer |
Sanity Option
We can create a new field on Sanity that will map the available payment methods with the flag TRUE or FALSE for isOnlinePayment question.
...
Cons: Strange memory cache and/or CDN cache, not reliable to replicate configs in real time
Feature Flag Option
We should create a new Feature Flag on Launch Darkly with the following definitions:
...
Code Block |
---|
{ "limit_first_order": { "active": true, "amount": 20, "amount_in_cents": 2000 }, "limit_total_amount": { "active": true, "amount": 50, "amount_in_cents": 5000 }, "limit_last_delivery_failed": { "active": false, "reasons_to_limit": { "customer_absence": true, "reason2": false, "reason3": true } } } |
Variation option to consider payment methods
In case we need to map the physical payment methods in a configurable way
Code Block |
---|
{ "payment_methods": { "cash": false, "cc": true, "debit_online": true }, "rules": { "limit_first_order": { "active": true, "amount": 20, "amount_in_cents": 2000 }, "limit_total_amount": { "active": true, "amount": 50, "amount_in_cents": 5000 }, "limit_last_delivery_failed": { "active": false, "reasons_to_limit": { "customer_absence": true, "reason2": false, "reason3": true } } } } |
Rules Implementation
Rule 1 - First Order Physical Payment Limit
For the first order with a value >= X €, only online payment will be allowed, where X is configurable. The initial intention is to set it to 20 €.
...
When this count is 0, we don’t show Physical Payments.
Rule 2 - Physical Payment Amount Limit
For subsequent orders with a value >= X €, only online payment will be allowed, where X is configurable. The initial intention is to set it to 50 euros.
...
Create feature flag for this limit
Evaluate when creating PaymetMethods
Rule 3 - Repeated Delivery Failure

If the last order was paid in Physical Payments and there was a delivery failure (e.g. a joke order), the next order will only allow online payment
