`GrowSurfTaxInfoSaveResponse` | `success`, `taxInfo` | | `GrowSurfLeaderboardResponse` | `participants`, `nextKey`, `page`, `hasMore` | | `GrowSurfLeaderboardParticipant` | `id`, `rank`, `monthlyRank`, `prevMonthlyRank`, `email`, `isWinner`, `referralCount`, `monthlyReferralCount`, `prevMonthlyReferralCount`, `pendingReferralCount`, `revenueAmount`, `commissionAmount` | | `GrowSurfReferralSummary` | `referrals`, `leads`, `expiredReferrals`, `clicks`, `rewardsEarned`, `pendingRewards`, `invitesSent`, `currencyISO` | | `GrowSurfAffiliateSummary` | `referralRevenue`,

`.file`, `.link`, or `.text`. Items keep the server-authorized order. `category` can be `nil`. A FILE contains only safe display metadata; call `getParticipantResourceDownloadURL(resourceId:)` when the participant opens it. The response never includes private storage coordinates or a durable file URL. {% hint style="info" %} `GrowSurfWindowCampaign.design` carries the raw `participantAvatarStyle` value for custom screens. It is `CHARACTERS`, `INITIALS`, `ANIMALS`, or `GRADIENT`. The built-in window renders it automatically. Treat a missing or unknown value as `INITIALS`. {% endhint %} {% hint style="info" %} `payoutDestinations` is `nil` when no payout provider applies to the participant. If you build your own settings UI, render `providerDisplayName` instead of hardcoding a provider name, show the payout method picker when `requiresChoice` is `true`, and show the confirm action only when that provider's `canConfirm` is `true`. The PayPal-specific `provider` and `paypalEmailAddress` fields still work as before. {% endhint %} ## Advanced protocols and stores Use these APIs for tests or custom storage/transport integrations. | Type | Public methods | | ------------------------------------------- | ----------------------------------------------------------------------------------------------------- | | `GrowSurfHTTPClient` | `data(for:)` | | `GrowSurfTokenStore` | `sessionToken()`, `participantToken()`, `saveSessionToken(_:)`, `saveParticipantToken(_:)`, `clear()` | | `GrowSurfAttributionStore` | `attribution()`, `saveAttribution(_:)`, `clearAttribution()` | | `GrowSurfMobileInstanceIdStore` | `mobileInstanceId()` | | `GrowSurfWindowCacheStore` | `windowData(cacheKey:now:)`, `saveWindowData(_:cacheKey:expiresAt:)`, `clear()` | | `GrowSurfUserDefaultsAttributionStore` | UserDefaults-backed attribution store. | | `GrowSurfUserDefaultsMobileInstanceIdStore` | UserDefaults-backed mobile instance ID store. | | `GrowSurfUserDefaultsWindowCacheStore` | UserDefaults-backed window cache store. | | `GrowSurfFileWindowCacheStore` | File-backed window cache store used by default. | | `GrowSurfKeychainTokenStore` | Keychain-backed token store used by default. | ## Errors `GrowSurfError` can be: * `invalidURL` * `missingSessionToken` * `missingParticipantToken` * `invalidResponse` * `httpStatus(Int, String?)` --- # Agent Instructions This documentation is published with GitBook.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://docs.growsurf.com/developer-tools/ios-sdk/models-and-errors.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
