title1 - TASK: Create a new promo code flow for loyalty
  • Create a feature flag;

  • 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)

  • We will create a new hook to contain all the rules of this flow

    • 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

        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]);

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.

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

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

  3. Verify the need for other validations

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

title5 - TASK: Clean the applied offer when finished the order
  • 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

Code Block
languagetypescript
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
