Explanation of Change

Phase 1 (PR #83669, already merged) added the getCardSettings(cardSettings, feedCountry?) utility and routed all callers through it. However, no caller currently passes feedCountry.

Phase 2 (Auth PR #20194) switches the backend to push full nested card settings ({ US: {...}, GB: {...}, TRAVEL_US: {...} }) instead of flat per-feed objects. Without this change, all callers of getCardSettings would receive the full nested object back, and settings?.paymentBankAccountID etc. would be undefined since those fields are nested under program keys rather than at root.

This PR makes getCardSettings smart enough to handle both formats:

  • When feedCountry is provided: extracts the nested sub-object and merges it with root-level properties (like domainName, preferredPolicy) so callers still have access to everything
  • When feedCountry is NOT provided: auto-detects the program by trying known card program keys in priority order (USCURRENTGB), then merges
  • Legacy fallback: if no nested keys are found, returns the flat root settings as-is (backward compatible)

This follows the same merge pattern already used by getTravelSettings in TravelInvoicingUtils.ts.

Fixed Issues

$ #81472

Tests

  • Verify that no errors appear in the JS console
  1. Run npx jest tests/unit/CardUtilsTest.ts --testNamePattern="getCardSettings" — all 11 tests pass
  2. Verify existing card settings pages still work correctly (paymentBankAccountID, settlement account, etc. are still accessible)

Offline tests

N/A — no network behavior changes, this is a pure data-layer utility change.

QA Steps

  • Verify that no errors appear in the JS console
  1. Open any workspace's Expensify Card page
  2. Verify card settings (settlement account, frequency) display correctly
  3. Open Travel Invoicing page
  4. Verify travel settings display correctly
  5. Navigate back to Expensify Card page — verify card settings are still intact (not clobbered)

    • Android: Native
    • Android: mWeb Chrome
    • iOS: Native
    • iOS: mWeb Safari
    • MacOS: Chrome / Safari
  • I verified there are no console errors (if there's a console error not related to the PR, report it or open an issue for it to be fixed)
  • I followed proper code patterns (see Reviewing the code)

    • I verified any copy / text shown in the product is localized by adding it to src/languages/* files and using the translation method
      • If any non-english text was added/modified, I used JaimeGPT to get English > Spanish translation. I then posted it in #expensify-open-source and it was approved by an internal Expensify engineer. Link to Slack message:
    • I verified all numbers, amounts, dates and phone numbers shown in the product are using the localization methods
    • I verified any copy / text that was added to the app is grammatically correct in English. It adheres to proper capitalization guidelines (note: only the first word of header/labels should be capitalized), and is either coming verbatim from figma or has been approved by marketing (in order to get marketing approval, ask the Bug Zero team member to add the Waiting for copy label to the issue)
    • I verified proper file naming conventions were followed for any new files or renamed files. All non-platform specific files are named after what they export and are not named "index.js". All platform-specific files are named for the platform the code supports as outlined in the README.

  • I verified any variables that can be defined as constants (ie. in CONST.ts or at the top of the file that uses the constant) are defined as such
  • I verified that if a function's arguments changed that all usages have also been updated correctly
  • If any new file was added I verified that:
    • The file has a description of what it does and/or why is needed at the top of the file if the code is not self explanatory
  • If a new CSS style is added I verified that:
    • A similar style doesn't already exist
    • The style can't be created with an existing StyleUtils function (i.e. StyleUtils.getBackgroundAndBorderStyle(theme.componentBG))
  • If new assets were added or existing ones were modified, I verified that:
    • The assets are optimized and compressed (for SVG files, run npm run compress-svg)
    • The assets load correctly across all supported platforms.
  • If the PR modifies code that runs when editing or sending messages, I tested and verified there is no unexpected behavior for all supported markdown - URLs, single line code, code blocks, quotes, headings, bold, strikethrough, and italic.
  • If the PR modifies a generic component, I tested and verified that those changes do not break usages of that component in the rest of the App (i.e. if a shared library or component like Avatar is modified, I verified that Avatar is working as expected in all cases)
  • If the PR modifies a component related to any of the existing Storybook stories, I tested and verified all stories for that component are still working as expected.
  • If the PR modifies a component or page that can be accessed by a direct deeplink, I verified that the code functions as expected when the deeplink is used - from a logged in and logged out account.
  • If the PR modifies the UI (e.g. new buttons, new UI components, changing the padding/spacing/sizing, moving components, etc) or modifies the form input styles:
    • I verified that all the inputs inside a form are aligned with each other.
    • I added Design label and/or tagged @Expensify/design so the design team can review the changes.
  • If a new page is added, I verified it's using the ScrollView component to make it scrollable when more elements are added to the page.
  • I added unit tests for any new feature or bug fix in this PR to help automatically prevent regressions in this user flow.
  • If the main branch was merged into this PR after a review, I tested again and verified the outcome was still expected according to the Test steps.

❌ CONSISTENCY-2 (docs)

The string literals 'CURRENT' and 'GB' are hardcoded magic strings. 'GB' already has a constant defined at CONST.COUNTRY.GB (the same line already uses CONST.COUNTRY.US, so this is inconsistent). 'CURRENT' has no constant defined anywhere and should be added to a relevant CONST object (e.g., CONST.EXPENSIFY_CARD.CARD_PROGRAM.CURRENT or similar) so its meaning is discoverable and centralized.

Additionally, 'CURRENT' and 'GB' are not represented in the ExpensifyCardSettings type definition (only US and TRAVEL_US are typed as optional nested keys). This means cardSettings[key as keyof typeof cardSettings] relies on an unsafe as cast to access keys the type system doesn't know about. Consider adding CURRENT?: ExpensifyCardSettingsBase and GB?: ExpensifyCardSettingsBase to the ExpensifyCardSettings type to make these accesses type-safe.

Suggested fix:

// 1. Add to CONST (or appropriate location):
CARD_PROGRAM: {
    CURRENT: 'CURRENT',
} as const,

// 2. Update ExpensifyCardSettings type to include GB and CURRENT:
type ExpensifyCardSettings = OnyxCommon.OnyxValueWithOfflineFeedback<
    ExpensifyCardSettingsBase & {
        US?: ExpensifyCardSettingsBase;
        GB?: ExpensifyCardSettingsBase;
        CURRENT?: ExpensifyCardSettingsBase;
        TRAVEL_US?: ExpensifyCardSettingsBase;
        hasOnceLoaded?: boolean;
    }
>;

// 3. Use constants on line 1102:
const result = tryNested(CONST.COUNTRY.US) ?? tryNested(CONST.EXPENSIFY_CARD.CARD_PROGRAM.CURRENT) ?? tryNested(CONST.COUNTRY.GB);

LGTM. I checked out the branch locally and merged in the latest main so that it will have the 1:1:1 changes, and it works perfect! Toggled it on and off and inspected the onyx data being returned. Handled it perfectly 👍

P1 Badge Respect root updates when merging nested card settings

This merge order makes nested values always override root values, so root-level optimistic writes are dropped whenever a nested program object exists. In this repo, updateSettlementAccount and updateSettlementFrequency still write paymentBankAccountID/monthlySettlementDate at the root of PRIVATE_EXPENSIFY_CARD_SETTINGS (src/libs/actions/Card.ts), so after this change getCardSettings() can keep returning stale nested values and the settings UI may not reflect account/frequency changes until a full server refresh (or at all if no nested update arrives).

good catch — flipped the merge order to {...programSettings, ...cardSettings} so root-level optimistic writes (e.g. paymentBankAccountID from updateSettlementAccount) take precedence over stale nested values. nested-only fields still come through since root won't have them

P1 Badge Preserve nested program fields over root in merged card settings

Spreading programSettings before cardSettings lets root-level fields overwrite the selected program payload, which can surface the wrong card config once Phase 2 sends multiple nested programs under one key. In this repo, Travel Invoicing actions still write fields like paymentBankAccountID and isEnabled at the root of the same private_expensifyCardSettings_* entry, so after a travel update a US card read can be overwritten by travel/root values even when US nested data is correct; this affects callers like workspace Expensify Card pages that rely on getCardSettings() for settlement/account state.

reverted back to {...root, ...nested} — nested program values are the authoritative source from the backend, this matches the existing getTravelSettings pattern. optimistic writes are temporary and get corrected by the server response, so nested should win to avoid cross-program leakage (e.g. travel paymentBankAccountID at root overwriting the correct US nested value)
