Business rules

The new payment method should only be available if the user selects “delivery mode” inside the Whitelabel App
The confirmation/tracking page should show the correct text in the payment reminder for this new payment method
The receipt email should show the correct payment option for this new payment method
The new method should be available in the user account methods list

Tasks breakdown

The solution was based on the Sodexo Cheque Gourmet Voucher implementation: https://github.com/rbilabs/intl-whitelabel-app/pull/686/files

Task 1: Create a new feature flag

Flag should be added in: frontend/src/utils/launchdarkly/flags.ts

Suggestion name: enable-payment-on-delivery-card

The user can pay using credit or debit mode, so “card” is a generic name

https://app.launchdarkly.com/intl-guest-app/dev-plk-es/features/enable-payment-on-delivery-card-paycomet/targeting

Task 2: Add the new payment method in the payment state and structure

Create a new placeholder for the new payment method
- The idea is to send this new payment method identified as cash

Expand

title	frontend/src/state/payment/constants.ts

Code Block

language	typescript

// Replace this name for what we decide
export const NEW_PAYMENT_METHOD_PLACEHOLDER: IPaymentMethod = {
  sodexo: false,
  fdAccountId: 'CASH',
  accountIdentifier: 'NEW_PAYMENT_METHOD', // TO BE DEFINED
  paymentMethodBrand: 'NEW_PAYMENT_METHOD', // TO BE DEFINED
  chaseProfileId: null,
  credit: null,
  prepaid: null,
  paypalIdentifier: null,
  ideal: null,
  paypal: false,
};

Add the new payment method in getPaymentMethodsState:

Expand

title	frontend/src/state/payment/hooks/getPaymentMethodsState/index.ts

Update the interface:

frontend/src/state/payment/hooks/types.ts:

Code Block

language	typescript

export interface ISetupPaymentMethodState {
  enableNewMethod: boolean;
}

Adjust the getPaymentMethodsState:

Code Block

language	typescript

export const getPaymentMethodsState = ({
  // rest of the code
  enableNewMethod,
}: ISetupPaymentMethodState) => {
  // rest of the code

  if (enableNewMethod) {
    availablePaymentMethodList.push(NEW_PAYMENT_METHOD_PLACEHOLDER);
  }
  // rest of the code
};

Adjust the payment hook

Expand

title	frontend/src/state/payment/hooks/use-payment.tsx

Update cash account variable:

Code Block

language	typescript

const cashAccount: IPaymentMethod = {
  // rest of the code
  newMethod: null,
};

Add the new feature flag here and then pass through the getPaymentMethodState:

Code Block

language	typescript

const usePayment = ({
  // rest of the code
  const enableNewMethod = useFlag(LaunchDarklyFlag.ENABLE_CREDIT_CARD_AT_HOME_PAYCOMET); // new line
  
  
    const initPaymentMethods = useCallback(() => {
      const {
        availablePaymentMethodList,
        validDefaultPaymentMethodId,
        validDefaultReloadPaymentMethodId,
      } = getPaymentMethodsState({
         enableNewMethod, // new line here
      });
    },
    []
  );
});

Adjust the unit tests mocking the new flag where necessary: frontend/src/state/payment/tests/use-payment.test.tsx

Adjust use-order-payment hook

Expand

title	frontend/src/pages/cart/payment/order-payment/use-order-payment.ts

Add a new state for the new payment method:

const [isPaycometNewMethodSelected, setIsPaycometNewMethodSelected] = useState('');

Update the handlePaymentMethodSelected adding the new method:

Code Block

language	typescript

  const handlePaymentMethodSelected = (newFdAccountId?: string) => {
    if (!newFdAccountId) {
      payment.setCheckoutPaymentMethodId('');
      return;
    }
    
    // rest of the code
    setIsPaycometNewMethodSelected(''); // New line
  };

Clear our new method in the useEffect logic that already exist:

Code Block

language	typescript

  // when checkout payment method have been updated from payment context
  // the flags to show add new credit card or add gift card
  // have to be updated.
  useEffect(() => {
      // rest of the code
      setIsPaycometNewMethodSelected('');
    }
  }, [setCheckoutPaymentMethodId, checkoutPaymentMethodId]);

Update the placeOrder function to deal with the new method:

Option 1:

Adjust the if condition for paycomet processor to deal with the new method:

Code Block

language	typescript

} else if (payment.isPaycomet) {
        // rest of the code
        if (payCometValues.isPaypal) {
          // rest of the code
        } else {
          // add a new condition here for our new method, like the sodexo one
          let paymentMethodBrandValue = undefined;
          if (isPaycometSodexoMethodSelected || isPaycometChequeGourmetMethodSelected) {
            paymentMethodBrandValue = isPaycometSodexoMethodSelected
              ? PaymentMethodBrand.SODEXO
              : PaymentMethodBrand.CHEQUE_GOURMET;
          }
          commitInput = {
            // rest of the code
          };
      }
  // rest of the code

Option 2:
- Separate this logic in another reusable block and then pass the new paymentMethodBrand (as a kind of builder pattern or something similar). We can discuss that on an A&D section.

Adjust the processOrderWithAccount function for the new method like this Sodexo example:

Code Block

language	typescript

        // rest of the code
        const isPaymentWithVoucher =
          paymentAccount.paymentMethodBrand === PaymentMethodBrand.SODEXO_VOUCHER ||
          paymentAccount.paymentMethodBrand === PaymentMethodBrand.CHEQUE_GOURMET_VOUCHER;
        if (payment.checkoutPaymentMethodId === CASH_ACCOUNT_IDENTIFIER || isPaymentWithVoucher) {
          const paymentDetails: IPayment = {
            cashPayment: true,
            fullName,
            paymentMethodBrand: paymentAccount?.paymentMethodBrand ?? undefined,
          };

          if (payment.isVrPayment) {
            // The GraphQL endpoint for VR Payment expects this object even
            // for Cash orders, otherwise the order creation fails
            paymentDetails.vrPaymentInput = {
              merchantAccount: '',
              pspReference: '',
              storePaymentMethod: true,
            };
          }

          return commitOrder({
            ...commitInput,
            creditType: CASH_ACCOUNT_IDENTIFIER,
            payment: paymentDetails,
          });
        }

Adjust the handleOrderCommit to place the order with the new method:

Code Block

language	typescript

      // Add new condition here as the isPaymentWithVoucher from the Sodexo example
      
      const isPaymentWithVoucher = isPaymentWithSodexoVoucher || isPaymentWithChequeGourmetVoucher;

      if (
        (showAddPaymentMethod ||
          isAdyenBlikMethodSelected ||
          reloadAddPaymentMethod ||
          isPayPalRegistration) &&
        !(selectedPaymentMethod?.cash || isPaymentWithVoucher || payment.isFreeOrderPayment)
      ) {
        await placeOrder();
      } else {
        await placeOrderWithAccount();
      }

Extend the getCurrentSelectedMethodType:

Expand

title	frontend/src/components/payment-method/utils/get-current-selected-method-type.ts

Add the new payment in the enum CurrentSelectedMethodType:

frontend/src/components/payment-method/types.ts:

Code Block

language	typescript

export enum CurrentSelectedMethodType {
  // rest of the code
  ADD_NEW_PAYMENT_NEW_METHOD = 'addNewPaymentNewMethod',
}

Adjust the IPaymentMethodProps:

Code Block

language	typescript

export interface IPaymentMethodProps {
  // rest of the code
  setIsPaycometNewMethodSelected?: Dispatch<SetStateAction<string>>;
  isPaycometNewMethodSelected?: string;
}

Add the new condition in getCurrentSelectedMethodType:

Code Block


type GetCurrentSelectedMethodTypeParams = {
  // rest of the code
  isPaycometNewMethodSelected?: string;
};

function getCurrentSelectedMethodType({
  // rest of the code
  isPaycometNewMethodSelected
}: GetCurrentSelectedMethodTypeParams): CurrentSelectedMethodType {
  let currentSelectedMethodType = CurrentSelectedMethodType.ADD_NEW_PAYMENT_METHOD;
  // rest of the code
  if (isPaycometNewMethodSelected === 'card') {
    currentSelectedMethodType = CurrentSelectedMethodType.ADD_NEW_PAYMENT_NEW_METHOD;
  }
  // rest of the code
}

Adjust order-payment comp:

Expand

title	frontend/src/pages/cart/payment/order-payment/payment.tsx

Return the new create state from useOrderPayment:

Code Block

language	typescript

  const {
   // rest of the code
   isPaycometNewMethodSelected, // new line here
  } = useOrderPayment({
    serverOrder,
    onPriceOrder,
    enableOrderTimedFire,
  });

Pass the returned value to the getCurrentSelectedMethodType:

Code Block

language	typescript

  const currentSelectedMethodType = getCurrentSelectedMethodType({
    isPaycometNewMethodSelected,
  });

Pass the new method to the <PaymentMethod> comp:

Code Block

language	typescript

<PaymentMethod
   // rest of the code
   isPaycometNewMethodSelected={isPaycometNewMethodSelected}
/>

Task 3: Add the new method in payment-method structure

Create new styled component for the new payment method

Expand

title	frontend/src/components/payment-method/styled.ts

Code Block

language	typescript

// ... rest of the file
export const StyledNewMethodCardIcon = styled(IconNewMethod)`
  ${cardIconSize}
`;

Add a new type

Code Block

language	typescript

export type PaymentMethodOptionProps = {
  // ... rest of the file
  setIsPaycometNewMethodSelected?: Dispatch<SetStateAction<string>>;
};

Add the new method in payment-method comp

Expand

title	workspaces/frontend/src/components/payment-method/index.tsx

Add new props in PaymentMethod:

Code Block

language	typescript


function PaymentMethod({
  // rest of the code
  isPaycometNewMethodSelected,
  setIsPaycometNewMethodSelected,
}: IPaymentMethodProps) {
  // rest of the code
  
  // pass the new prop in the getCurrentSelectedMethodType
  const currentSelectedMethodType = getCurrentSelectedMethodType({
    isPaycometNewMethodSelected
  });
});

Create new item inside PaymentMethod comp:

Code Block

language	jsx

// ... rest of the file
const SelectedNewMethodOptionItem = (
  <PaymentMethodAddNewItemOption
    data-testid="payment-new-method-name"
    text={formatMessage({ id: 'addNewPaymentNewMethod' })}
    Icon={<StyledNewMethodCardIcon />}
    onClick={getSelectedMethodClickHandler()}
    selected
  />
);

Add the new method in the map structure:

Code Block
const CurrentSelectedMethodMap = { // ... rest of the file [CurrentSelectedMethodType.ADD_NEW_PAYMENT_METHOD]: SelectedNewMethodOptionItem, };

Pass the new prop in the <PaymentMethodOptions> comp:

Code Block

language	tsx

 <PaymentMethodOptions
    setIsPaycometNewMethodSelected={setIsPaycometNewMethodSelected}
  />

Add the new method in payment-method-options comp

Expand

title	frontend/src/components/payment-method/payment-method-options/payment-method-options.tsx

Add the new prop in PaymentMethodOptions comp:

Code Block

language	typescript

function PaymentMethodOptions({
  // .. rest of the file
  setIsPaycometNewMethodSelected
}: PaymentMethodOptionProps) {
  const enableNewMethod = useFlag(LaunchDarklyFlag.ENABLE_CREDIT_CARD_AT_HOME_PAYCOMET); // new line

});

Add new condition in handleUnselectedMethodClick, handleAddNewCardOptionClick, handleAddNewGiftCardOptionClick, handlePaypalOptionClick and handleAdyenIdealOptionClick to clear our new state:

Code Block

language	typescript

  if (setIsPaycometSodexoOptionSelected) {
    setIsPaycometNewMethodSelected('');
  }

Add a new handle for our new method (using useCallback) where we’ll clear the other methods and set your:

Code Block

language	typescript

  const handleNewMethodOptionClick = useCallback(
    (e: React.FormEvent<HTMLButtonElement>, newMethodType: string) => {
      e.preventDefault();
      setIsAddNewCardOptionSelected(false);
      setIsAddNewGiftCardOptionSelected(false);
      if (setIsPaycometPaypalOptionSelected) {
        setIsPaycometPaypalOptionSelected(false);
      }
      if (setIsAdyenIdealOptionSelected) {
        setIsAdyenIdealOptionSelected(false);
      }
      if (setIsAdyenBlikOptionSelected) {
        setIsAdyenBlikOptionSelected(false);
      }
      if (setIsPaycometSodexoOptionSelected) {
        setIsPaycometSodexoOptionSelected('');
      }
      if (setIsPaycometSodexoOptionSelected) {
        setIsPaycometSodexoOptionSelected('');
      }
      // our new method here
      if (setIsPaycometNewMethodSelected) {
        setIsPaycometNewMethodSelected(newMethodType);
        if (newMethodType === 'card') {
          setIsAddNewCardOptionSelected(true);
        }
      }

      handleSelect();
      setCollapsed(true);
    },
    [
     // callback dependencies here
    ]
  );

Add in the enableSortPaymentMethods && unSelectedMethods.map a new block for our new method:

We also need to condition this payment method to be shown only if delivery mode is selected

Code Block

language	tsx

const isDelivery = serverOrder?.delivery;

{method?.newMethod && method?.transient && isDelivery && (
  <StyledOption>
    <PaymentMethodOptionItemDivider />
    <PaymentMethodAddNewItemOption
      data-testid="add-new-method-payment"
      text={formatMessage({ id: newMethodLabel(isGuestOrder) })}
      Icon={<StyledNewMethodCardIcon />}
      onClick={e => handleNewMethodOptionClick(e, 'card')}
      isLoading={isLoadingPopup}
    />
  </StyledOption>
)}

Add a new block for for the case where we not have the enableSortPaymentMethods as true:

Code Block

language	tsx

{!enableSortPaymentMethods && enableNewMethod && (
  <StyledOption>
    <PaymentMethodOptionItemDivider />
    <PaymentMethodAddNewItemOption
      data-testid=add-new-method-payment"
      text={formatMessage({ id: newMethodLabel(isGuestOrder) })}
      Icon={<StyledNewMethodCardIcon />}
      onClick={e => handleNewMethodOptionClick(e, 'card')}
      isLoading={isLoadingPopup}
    />
  </StyledOption>
)}

Add the new payment method in the sortPaymentMethods

frontend/src/components/payment-method/utils/sort-payment-methods.ts

Code Block

language	typescript

  const paymentMethodListTypeOrder = [
    // rest of the code
    'NEW_METHOD',
  ];
  
  // Add new case in switch for our new method
  function filterMethodByType(typeOrder: string, paymentMethods: IPaymentMethod[]): IPaymentMethod[] {
  switch (typeOrder) {
    // rest of the code
    case 'NEW_METHOD':
      return paymentMethods.filter(
        p => !p?.transient && p?.newMethod && p.accountIdentifier === typeOrder
      );
    // rest of the code
  }
}

Add a new logic to the filter !enableSortPaymentMethods && unSelectedMethods.filter(isNotLocalWallet)... to now show our payment method if delivery mode is not selected:

Code Block

language	typescript

  const isDelivery = serverOrder?.delivery;

  const isNotLocalWallet = (method: IPaymentMethod) => {
    return !method.blik && !method.ideal;
  };

  const sortedMethodsFilterConditions = (method: IPaymentMethod) => {
    if (method.newMethod && !isDelivery) {
      return false; // remove our item from the list if delivery is not selected
    }

    return isNotLocalWallet(method);
  };
      
      // A suggestion would be the creation of a new function for the filter conditions
      {!enableSortPaymentMethods &&
        unSelectedMethods.filter(sortedMethodsFilterConditions).map(method => {

Add the new method in paycomet-hosted-page-payment comp

title	frontend/src/pages/cart/payment/order-payment/paycomet-hosted-page-payment/paycomet-hosted-page-payment.tsx

Return the new values from the useOrderPayment hook

Code Block

language	typescript

const {
    // rest of code
    setIsPaycometNewMethodSelected,
    isPaycometNewMethodSelected,
  } = useOrderPayment({
    enableOrderTimedFire,
    onPriceOrder,
    serverOrder,
  });

Pass down the values to the <PaymentMethod> comp

Code Block

language	tsx

// rest of the code
<PaymentInfoBackground $hostedPayment>
  {showPaymentMethodSelection && (
    <PaymentMethod
      // rest of the code
      setIsPaycometNewMethodSelected={setIsPaycometNewMethodSelected} // new line
      isPaycometNewMethodSelected={isPaycometNewMethodSelected} // new line
      onResult={onPaymentOutcome}
    />
  )}

Task 4: Create and add a new method in payment-method-option structure

Image Added

Add the new icon for the new payment method in: frontend/src/components/icons/new-payment-method/index.tsx (replace “new-payment-method” for the new name, hahaha).
- We can use the https://react-svgr.com/playground/ to convert the svg code from Figma to use in our code (following the pattern of the application)
Add the new method option in the interface of payment methods:

Expand

title	frontend/src/state/payment/types.ts

Code Block

language	typescript

export interface IPaymentMethod {
  // rest of the code
  newPaymentMethod?: boolean | null;
}

Add new file in frontend/src/components/payment-method-option/as the following example:
- Remember to add the translation that will be used in formatMessage

Expand

title	frontend/src/components/payment-method-option/new-payment-method.tsx (example of new file)

Code Block

const NewPaymentMethod = () => { // Example SodexoMethod
  const { formatMessage } = useIntl();

  return <MethodType>{formatMessage({ id: 'payWithNewMethod' })}</MethodType>;
};

export default NewPaymentMethod;

Use the created payment method option in payment-method-option:

Adjust the RenderMethodType and add the new method created above

Code Block

language	tsx


  const RenderMethodType = () => {
    // rest of the code

    // New if here
    if (method.newPaymentMethod) {
      return <NewPaymentMethod />;
    }   
    
    return null;
  };
  
  // add the new payment method inside the <MethodTypeWrapper> in the return
  
   return

  );

Task 5: Adjust account payment method lists to deal with the new method

Image Added

Expand

title	frontend/src/components/payment-method-flat-list-with-button/payment-method-flat-list-with-button.tsx

We’ll exclude the new payment method if it is not actually stored in the user account:

Code Block

language	typescript

function filterOutUnsupportedPaymentMethods(paymentMethods: IPaymentMethod[]) {
  return paymentMethods.filter(
    n =>
      n.accountIdentifier !== PAYPAL_PAYMENT_METHOD_PLACEHOLDER.accountIdentifier &&
      n.accountIdentifier !== SODEXO_VOUCHER_PAYMENT_METHOD_PLACEHOLDER.accountIdentifier &&
      n.accountIdentifier !== NEW_PAYMENT_METHOD_PLACEHOLDER.accountIdentifier &&
  );
}

Nice to have - not considered now

Task 6: Adjust the confirmation text for confirmation page and tracking modal

Image Added

The same component is used to show both cases: frontend/src/pages/order-confirmation/delivery/delivery-details.tsx

Suggestion of implementation:

Add a new property/flag inside the cart.payment structure to enable a new condition to show new texts for these case (I think that perhaps we should not change the cardType, not sure yet)
Image Added

For the payment reminder tip we have some options:

Image Added

Create new component as the <CashPaymentReminder /> that we have today for the new condition/new text
Adjust the <CashPaymentReminder /> to deal with other types of texts and perhaps rename this component to have a generic name (for example <PaymentReminder />)

Task 7: Adjust the receipt email to show the correct message for the new payment method

Image Added

Today, when the commit order is processed, order-service triggers Braze API with the order info, that then sends the confirmation email to the customer.

The first necessary alteration will be to include paymentMethodBrand in the properties sent to braze in transformOrderProperties utility method. For example:

Expand

title	packages/emails/src/utils.ts

Code Block

language	js

export const transformOrderProperties = ({
  rbiOrder,
  brand,
  fzStore,
  language,
}: ITransformOrderProperties): Record<string, any> => {
  ...
  const { cardType, ccLast4: last4, paymentType, paymentMethodBrand }: Partial<IPayment> = payment || {};
  ...
  properties.paymentMethodBrand = paymentMethodBrand;
  return properties;
}

After we change intl-packages/email to send the necessary information to Braze API, we need to update the templates configured, which are split into templates and content blocks (reusable pieces of content). Using PLK-ES as example we can see:

Note
The example displays a LiquidJS template, which is similar but not equal to Braze templates. Braze access properties using the syntax `{{event_properties.${language}}}`

Expand

title	LiquidJS template example

Code Block

{% assign people = "alice" | split: ", " -%}
{% assign cardType = "CASH"  %}
{% assign paymentMethodBrand = "PAYMENT_ON_DELIVERY_CARD"  %}

<ul>
{%- for person in people %}
  <li>
    <a href="{{person | prepend: "http://example.com/"}}">

    {{cardType}}
    Pagado con {% if cardType != "CASH" %} Tarjeta terminada en {{last4}} {% else %}{% if  paymentMethodBrand != nil %}{{paymentMethodBrand}} {%else%}efectivo {%endif%} {%endif%}
  </li>
{%- endfor%}
