🛠️ Potential Solutions

🧐 Assumptions

• We will only add the brands of credit cards in the “add new credit card” option.

• Do not show “sodexo”, “cheque gourmet” and “ticket restaurant” brands in the “add new credit card” option.

• Do not display card components for “sodexo”, “cheque gourmet” and “ticket restaurant”.

• Iframe loading is indifferent to card component details (can be shown before loading the iframe).

Solution #1 - Map cards accepted in whitelabel-app

The first solution is to add a mapper just to the frontend to obtain the types of cards accepted for payment and directly obtain these values ​​that will be displayed. Changing accepted cards is very infrequently, we would not have problems with changes in these fields.

Solution #2 - Get accepted cards in the launch-darkly

In this solution we would have the flexibility of a more dynamic change, but we would be linking the feature to the feature flag and adding another flag to the system.

Solution #3 - Get accepted cards in the backend

In this solution we created a more robust solution to store the types of cards accepted and retrieve them. This may involve adding the types of cards accepted to the database.

✅ Proposed Solution

Solution #2 - Get accepted cards in the launch-darkly

The change needed to add the flags is just a change in the paycomet-credit-card-form.tsx file. To do this, you need to create a component to add the flags and call it after paymentJetId is enabled, as it defines when the form is ready to be displayed to the user.

/**
 * This flag retrieve all accepted cards types.
 */
 ACCEPTED-CARDS-TYPES = 'accepted-cards-types',

const acceptedCardsFeatureFlag = useFlag(
    LaunchDarklyFlag.ACCEPTED_CARDS
);

const creditTypeAccepted = () => {
  if(sodexo || chequeGourmet || ticketRestaurant){
    return
  }
  
  const mappedAcceptedCards = acceptedCardsFeatureFlag.map((cardType) => {
    return (
      <Icon .... >
    )
  })
  
  return (
    <>
      <h3>Card Details</h3>
      {mappedAcceptedCards()}
    </>
  );
};

return (
  <>
    <PaymentMethodSelect>
    ...
    </PaymentMethodSelect>
    {isAddCardOpen && creditTypeAccepted()}
  </>
)

🎛️ Configuration

To configure the feature flag correctly, it is necessary to enable the feature flag and configure the variations to add the values ​​of the accepted card types. For example:

📈 Metrics

Reduce the abandonment rate in the payment process by 11.8%.

KPI = (Paycomet Error 102) / All Payments * 100

Error 102: Operation not permitted for card type.
