• Create a feature flag

  • ENABLE_LOYALTY_OFFER_PROMO_CODE_AT_CHECKOUT

• The first step to use the loyalty promo code at checkout will be to change the validation promo code flow.

  • On the promo code component field, we will need to add a feature flag:

    • When this flag is enabled: The promo code flow will be LOYALTY OFFER

    • When this flag is disabled: The promo code flow will be CBA OFFER (current flow)

• Where the new logic can be (two options):

  • A new hook to contain all the rules of this flow

    • The should be in app/workspaces/frontend/src/state/loyalty/hooks/use-redeem-promo-code-checkout

  • We can use the same hook used to offer page flow.

    • intl-whitelabel-app/workspaces/frontend/src/state/loyalty/hooks/use-redeem-promo-codes.ts

const onSubmitLoyaltyPromoCode = useCallback(async () => {
    setPromoCodeValidationLoading(true)

    // const loyaltyId = 'ec5cec01-b41b-509b-9111-310ab5a18154'

    let event = createRbiApplyPromoCodeEvent(promoCodeInput, 'Successful')
    const personalizedOffer = await redeemMutation(user?.loyaltyId || '', promoCodeInput)
      .catch((e: PromoCodeError) => {
        const reason = buildErrorMessageFromPromoCodeError(e)
        setPromoCodeErrorMessageId(
          (reason as TPromoCodeErrorMessageIds) || PromoCodeErrorMessageIds.default
        )

        logger.error(`Error validating promo code ${e}`)
        event = createRbiApplyPromoCodeEvent(promoCodeInput, 'Failed', e.message)
      })
      .finally(() => {
        setPromoCodeValidationLoading(false)
      })

    trackEvent(event)

    if (personalizedOffer) {
      await handleRedemption(personalizedOffer)

      // clear promo code input & error message
      setPromoCodeErrorMessageId(null)
      setPromoCodeInput('')

      toast.success(formatMessage({ id: 'offerAddedToCart' }))
    }
  }, [
    formatMessage,
    handleRedemption,
    promoCodeInput,
    redeemMutation,
    trackEvent,
    user?.loyaltyId,
  ])
  
  
   useEffect(() => {
    if (appliedOfferPromoCode?.loyaltyEngineId) {
      const standardOffersLimit =
        earningCalculationData?.EarningCalculation?.offerRedemptionLimits?.standardOffersLimit || 1

      dispatch(actions.loyalty.setSelectedOffer(appliedOfferPromoCode))
      dispatch(actions.loyalty.setAppliedOffers([appliedOfferPromoCode]))

      if (isDiscountLoyaltyOffer(appliedOfferPromoCode)) {
        // If limit of offers reached remove the first one
        if (appliedOffers?.length >= standardOffersLimit) {
          removeFromCart({ cartId: appliedOffers[0].cartId })
        }

        //Discount offers should not show menu item details
        dispatch(
          actions.loyalty.applyOffer({
            id: appliedOfferPromoCode.loyaltyEngineId,
            type: OfferType.GLOBAL,
            isStackable: appliedOfferPromoCode.isStackable,
            isSurprise: isSurpriseOffer(appliedOfferPromoCode),
            cmsId: appliedOfferPromoCode._id,
            cartId: 'discount-offer',
          })
        )
      }

      dispatch(actions.loyalty.setCmsOffers([appliedOfferPromoCode]))
      return
    }

    dispatch(actions.loyalty.setSelectedOffer(null))
    dispatch(actions.loyalty.setAppliedOffers([]))
    dispatch(actions.loyalty.setCmsOffers([]))

    // eslint-disable-next-line react-hooks/exhaustive-deps
  }, [appliedOfferPromoCode])

The code above was developed in the PoC and is a new code.

Attention points:

1. We need to apply (dispatch) the personalised offer on some contexts:

   1. actions.loyalty.setSelectedOffer(personalizedOffer)

   2. actions.loyalty.setAppliedOffers

   3. actions.loyalty.applyOffer

   4. actions.loyalty.setCmsOffers

OBS.: It’s possible we need to apply the offer in another context too.

2. When we click on remove in offer info (after applying the offer), we need to remove the offer in all contexts.

   

3. When the customers reload the page, the offer must continue applied.

4. Verify the need for other validations

5. If the user is not authenticated we need to ask for the login

   1. The behavior will be the same as we have on offers page

With this update, the frontend is prepared to apply the promo code to loyalty.

• We need to render only the input for the promotional code instead of the collapse structure if our flag is ON

  • Before

    

  • After our change (with our flag ON)

    

• Raphael Ferreira Gomes said that when the component is expanded some events are dispatched to mParticle. We need to validate what will happen if the component loads already expanded. now that the component will be loaded in the screen without the collapse. He recommended that we need to talk with Manuel (Ramon Manuel LuceroRodrigues da Silva) to understand if this will be a problem and what’s expect for the events part ← To be validate during development

  • Do we need to fire events if the component loads already expandedis already rendered in the screen?

This task was moved to another task

This task was moved to another task as this objective conflicts with we’ll do in the

Important (BLOCKED): apparently this flow changed in the current app and the result was not what Rodrigo showed in the screenshots below (redeem in restaurant modal). We don’t have enough time during the A&D to go deep on this. We can talk with de Sousa Santos, Rodrigo to understand better what code we should base in.

enough time during the A&D to go deep on this. We can talk with de Sousa Santos, Rodrigo to understand better what code we should base in.

There is a feature flag that limits what kind of modal should be shown: ENABLE_IMPROVED_SIMPLIFIED_REDEEM_IN_RESTAURANT_STATIC_OFFERS

With this flag on, we won’t have a close modal button like the one below:

And when it’s turned on it will be shown as below:

• When finish the order, we need to clean the offers on cookies, sessions, etc.

  • path: intl-whitelabel-app/workspaces/frontend/src/pages/order-confirmation/order-confirmation.tsx

  • Suggestion of PoC code: Instead of clear each state using a set function (showed in the PoC code below) we can improve this creating new slices to handle with the data clear:

    • selectedOffer state → We can create a new slice to clear/reset this state

    • appliedOffers state → We can reuse the resetAppliedOffers() slice that already exists to clear/reset this state instead of set an empty array

    • cmsOffers state → We can create a new slice to clear/reset this state

    • As last resource we can create a new slice to clear all the data related to the applied offer

useEffect(() => {
  if (!loading && !orderErrors) {
    dispatch(actions.loyalty.setSelectedOffer(null))
    dispatch(actions.loyalty.setAppliedOffers([]))
    dispatch(actions.loyalty.setCmsOffers([]))
  }
}, [dispatch, loading, orderErrors])

• After the order is finished, we need to apply the sanity rules too, for example:

  • If the number used voucher is 1, after the order, the offer should be removed from the offer page

    

  • we can use the same logic on the component OfferRedemptionModal

    • path: intl-whitelabel-app/workspaces/frontend/src/components/offer-redemption-modal/index.tsx

    • When we click on Redeem in Restaurant

      

    • Will show the modal and if we click on the close button, the offers will removed on the offer page. So we can use the same logic:

      

  • OBS: This relation between offer x customer, probably is saved on dynamoBD

    • We can find the answer on intl-promotion-service repository, from redeemCoupon method flow

• Create a feature flag in Tech Platform

  • ENABLE_AT_LOYALTY_OFFER_PROMOCODE_AT_CHECKOUT

  • Set settings env, brand, marketing

• Should enable SDK settings

  

• Update mapOrderDiscounts method to return the offer discount also.

  • path: intl-partners-service/src/modules/orders/orders.service.ts

  • Create function to get LaunchDarkly.

    • 

  • In the line 328 we should validate flag ENABLE_AT_LOYALTY_OFFER_CHECKOUT

    

  • To discover the discount values we will need to use the method getOffers

    • path: intl-partners-service/src/modules/orders/cart-total.service.ts

    • This method is private, so we will update it to public

  • After that, we will send the discount to Winrest via IWebhookPriceOrder adding the orderDiscounts

    

• Payload will be:
