Default/legacy behavior to apply different Config Offer types through offers page

Today the promotion code only supports Config Offer type Combo, Picker and Offer Discount.

...

Offer Combo/Picker

The behavior will be the same: when adding to the cart the user will be redirect to the menu item to configure the item and then apply to the cart:

...

Offer Discount

Different from Offer Picker or Offer Combo, the Offer Discount is added directly to the cart when applied. The user don't need to be redirected to the menu page.

Config Offer type that we support today at checkout page

...

• Offer Discount: This is the only offer that we are supporting on the checkout page today

• Combo and Picker: Not supported today

  • Current limitation: we need to bring the necessary logic for the other types of Config Offer to the checkout page when applying a promo code through our new feature/field

  • We are analyzing this subject on a PoC:

    server System JIRA serverId 255417eb-03fa-3e2f-a6ba-05d325fec50d key IBFEC-1505

    • The PoC will be useful to prove if we'll be able to bring the necessary logic and detect if this can cause any problems to the checkout page or the offers page legacy logic

How we can add support do Combo/Picker (PoC results and proposal of solution)

The main idea is to have the “same behavior” that we have on the /offers screen when dealing with a Combo/Picker offer. The main challenges that I faced here were:

...

• I was able to finish an order without any problem

  • The offer Combo/Picker was shown on the Recent Orders page and on the email receipt without any problem either.

• The validation of the item is working as expected. If I select a store that doesn’t have the item that my offer needs, the page will not let me use the item as expected for the legacy flow

Option 1 - Transform and apply “In-App Benefits” Combo/Picker item directly (desired)

From what I understood, we can’t directly use menu items from Sanity, meaning that we need to always convert the item using the utilities and methods from the Wizard architecture. With this in mind:

• Get the promotional Combo/Picker from the incentives array (configured on the Config Offer document) by adjusting the graphql query to get the whole item

• Transform the item and add it to the cart:

  • Use the transformMenuObjectToCartItemto convert the item configured on In-App Benefits

    • This method will be responsible for getting the price, modifiers, etc

    • This method needs to be properly filled out to get the correct data

    • Use ProductWizardUtils.ComputeSelectedOption to transform the itens correctly. This is important for Picker. The method will convert the Picker to a regular item

    • Use transformUserSelectionsComboToComboSlotSelections together with ProductWizardUtils.SetDefaultSelectionsto get the default values for a Combo item. As we are adding the offer Combo directly through the cart, we need to “select” the defaults for the user. This is important because we need the information in Recent Orders, etc.

  • Use the upsertCart from useOrderContext to add the promotional item to the cart

Problem with this solution: the Combo/Picker that comes from the Config Offer document will not have the vendorConfigs for the children items (sub-items) and without this information, when we add the item to the cart, we'll have only the main item, without the sub-items/modifiers.From what I understood, if an item doesn’t have the vendorConfig information, it will be considered invalid.

Option 2 - Query and validate the promotional item and then transform/apply

This solution is similar to Option 1 but here I solved the problem mentioned above:

Known problems/Problems to be solved

• Legacy bug: if the user presses F5 at the checkout page, the offer Combo/Picker will be removed from the Your Cart section. This is not related to our implementation or the PoC results.

Adds the ability to edit the Combo/Picker item

The main idea is to show the edit button for a Combo/Picker offer item, like the following example:

Assumptions and business rules

Questions and assumptions

Q: Today, when we redeem a promo code offer that has the type Combo/Picker on the offers page and the user clicks to add the offer to the cart, the application will redirect the user to the menu item (combo/picker) for the selected offer. On the menu page, the user can customize the Combo/Picker if allowed. If the user adds a Config Offer that has this type (Combo/Picker) through the checkout page, he'll not be able to customize the item. What will we do here? Can we consider the default options for the Combo/Picker?

...

A: We should keep the default behavior if possible:

• Add the item as an offer item

• Keep the default options selected for the user

• Show the “edit” button on the cart offer item (to be validated. PoC ongoing)

Business rules / Acceptance criteria

• The user should not be redirected to the menu page when applying a promotional code directly through the checkout page (for Offer Combo/Picker)

• Add the offer item with the defaults selections for the Combo/Picker

• Show the “edit” button on the cart offer item. The edit button should send the user to the menu page for the edited item (to be validated/aligned on PoC. In progress

  )

• The behavior must be closely to the legacy flow /offer page:

  • The item added to the cart should be exactly as we are adding it through the legacy flow (sub-items, price, etc)

  • The item should be correct at Recent Orders or email (like the legacy flow)

  • The offer item should not be available to add again to a new order after being used (blocked by the application by default).
