App Event Localizations
List all screenshots for an app event localization
Read a page of app event screenshot resources as flat JSON objects. Address an exact locale; the service resolves its localization ID.

| eventId | string | The selected resource’s ID. |
| locale | string | The exact locale to read. No fallback to a different locale. |
Query parameters
| Name | Type | Description |
|---|---|---|
| fields | string | Comma-separated attribute names to return. This selects read fields and does not expand relationships. Multiple values are comma-separated.ValuesfileSize, fileName, imageAsset, assetToken, uploadOperations, assetDeliveryState, appEventAssetType |
| limit | integer | Number of items per page, from 1 to 200. |
| cursor | string | Opaque nextCursor from a previous response. Keep the route, connection, filters, and ordering unchanged. |
Response
A page of flat objects, with an opaque continuation cursor.

Response fields
| Name | Type | Description |
|---|---|---|
| items | object[] | The current page of plain resource objects. An empty collection returns []. |
| nextCursor | string | null | Opaque continuation token, or null when the collection is complete. Pass it back as cursor. |
Each item
| Name | Type | Description |
|---|---|---|
| id | string | Apple’s resource ID. Keep this string unchanged when addressing a resource. |
| fileSize | integer | The file size in bytes. |
| fileName | string | The uploaded file’s name. |
| imageAsset | object | Apple’s image dimensions and URL template. The service does not download the image. |
| assetToken | string | The asset token value reported by Apple for this resource. |
| uploadOperations | object[] | Apple’s recorded upload-operation metadata. A GET does not perform these operations. |
| assetDeliveryState | object | The delivery state and any processing issues Apple reports for this asset. |
| appEventAssetType | string | The app event asset type value reported by Apple for this resource.ValuesEVENT_CARD, EVENT_DETAILS_PAGE |
| appEventLocalizationId | string | null | ID of the related app event localization. Present only when Apple supplies linkage; related objects are not loaded automatically. |
imageAsset fields
| Name | Type | Description |
|---|---|---|
| templateUrl | string | The template url value reported by Apple for this resource. |
| width | integer | The width value reported by Apple for this resource. |
| height | integer | The height value reported by Apple for this resource. |
uploadOperations fields
| Name | Type | Description |
|---|---|---|
| method | string | The method value reported by Apple for this resource. |
| url | string | The url value reported by Apple for this resource. |
| length | integer | The length value reported by Apple for this resource. |
| offset | integer | The offset value reported by Apple for this resource. |
| requestHeaders | object[] | The request headers value reported by Apple for this resource. |
uploadOperations.requestHeaders fields
| Name | Type | Description |
|---|---|---|
| name | string | The resource’s name. An app’s localized name is read from its app-info localization. |
| value | string | The value value reported by Apple for this resource. |
assetDeliveryState fields
| Name | Type | Description |
|---|---|---|
| errors | object[] | The errors value reported by Apple for this resource. |
| warnings | object[] | The warnings value reported by Apple for this resource. |
| state | string | The current state reported by Apple for this resource.ValuesAWAITING_UPLOAD, UPLOAD_COMPLETE, COMPLETE, FAILED |
assetDeliveryState.errors fields
| Name | Type | Description |
|---|---|---|
| code | string | The code value reported by Apple for this resource. |
| description | string | The localized store description. |
assetDeliveryState.warnings fields
| Name | Type | Description |
|---|---|---|
| code | string | The code value reported by Apple for this resource. |
| description | string | The localized store description. |
Behavior
- Resolve the exact locale within the selected parent, validate ownership, and read the resolved localization. No match returns localization_not_found; multiple matches return ambiguous_selection. GET does not create a locale or substitute another language.
Pagination
Pass nextCursor back as cursor with the same filters and ordering. Stop when it is null. Each request returns one bounded page; the service never reports a capped or incomplete traversal as a complete collection.
Errors
| HTTP | Type | Description |
|---|---|---|
| 400 | invalid_query | Unsupported filter, sort, limit, or cursor. |
| 401 | unauthorized | Missing or invalid facade API key. |
| 403 | forbidden / upstream_forbidden | The caller or configured Apple key cannot read this resource. |
| 404 | localization_not_found | The requested resource, parent, or exact locale is absent or outside the caller’s scope. |
| 409 | ambiguous_selection | More than one localization matches the selected parent and locale. |
| 429 | rate_limited | A facade or Apple rate limit was reached. Respect Retry-After when returned. |
| 502–504 | upstream error | Apple authentication, response parsing, availability, or timeout failure; this is not an empty result. |
Apple mapping
Upstream route and translation
The adapter calls GET /v1/appEventLocalizations/{id}/appEventScreenshots. Read Apple’s original endpoint ↗
Resolve the parent’s localization collection using the exact locale, validate ownership, and then supply the resolved ID to this Apple endpoint.
Flatten Apple’s attributes into each resource object. Expose supplied singleton linkage as IDs, with no automatic relationship traversal. Read access does not make these fields writable.
| Facade parameter | Type | Description |

| limit | query | limit |
| cursor | query | Facade-owned pagination |
