+# Configuring redirect behavior
+
+When a user selects a SharePoint Embedded file in Microsoft 365 search results, Microsoft 365 chooses a destination based on the file type. For files without a built-in Microsoft 365 web viewer, the destination depends on the `urlTemplate` property on the [container type](../../getting-started/containertypes.md). This article explains how Microsoft 365 chooses a destination and how to configure `urlTemplate` to route users to your application.
+
+## Prerequisites
+
+Before you configure `urlTemplate`, ensure you have:
+
+- A SharePoint Embedded [container type](../../getting-started/containertypes.md) that you own.
+- The Microsoft Graph permission `FileStorageContainerType.Manage.All` (delegated, work or school account). Application permissions aren't supported for [Update fileStorageContainerType](/graph/api/filestoragecontainertype-update).
+- `isDiscoverabilityEnabled` set to `true` on your container type's settings, so files in your containers appear in Microsoft 365 search results.
+
+## How Microsoft 365 chooses a destination for a search result
+
+The [`isDiscoverabilityEnabled`](/graph/api/resources/filestoragecontainertypesettings) setting on the container type controls whether a container's files appear in Microsoft 365 search results. Files appear in search only when `isDiscoverabilityEnabled` is `true` for their container type.
+
+When a user selects a SharePoint Embedded file from search results, the file opens in an appropriate viewer. For file types without a built-in Microsoft 365 viewer, the destination depends on the container type's [`urlTemplate`](/graph/api/resources/filestoragecontainertypesettings) property.
+
+If `urlTemplate` isn't configured, Microsoft 365 redirects users who select non-Office or non-PDF files to a generic Microsoft help page. The help page explains that the file is stored in a third-party application and directs the user to open it there.
+
+### How file types are handled
+
+The destination URL for a file in search results depends on the file type and whether `urlTemplate` is set:
+
+| File type | `urlTemplate` set? | Behavior when selected from search |
+| --- | --- | --- |
+| Files with a supported Microsoft 365 web viewer (Word, Excel, PowerPoint, Visio, OneNote, and others) | Either | Opens in the corresponding Microsoft 365 web viewer |
+| PDF | Either | Opens in the SharePoint Embedded PDF previewer |
+| All other types | Yes | Redirected to your application through `urlTemplate` |
+| All other types | No | Redirected to a [Microsoft help page](https://aka.ms/spe-openfilelocation) |
+
+## Configure `urlTemplate`
+
+Set the `urlTemplate` property on your container type by calling the [Update fileStorageContainerType](/graph/api/filestoragecontainertype-update) API. The value is a URL with placeholder tokens that Microsoft 365 resolves to actual item identifiers when a user selects a search result.
+
+### Requirements
+
+The `urlTemplate` value must:
+
+- Be a valid absolute URL that uses the `https://` scheme. HTTP URLs aren't accepted.
+- Not resolve to a loopback address, such as `localhost` or `127.0.0.1`.
+
+> [!IMPORTANT]
+> If the URL fails validation, `urlTemplate` is silently set to `null` without returning an error. To confirm your configuration, see [Verify your configuration](#verify-your-configuration).
+
+### URL template syntax
+
+```text
+https://app.contoso.com/open?tenant={tenant-id}&drive={drive-id}&item={item-id}
+```
+
+Each placeholder token uses curly braces. When a user selects a search result, Microsoft 365 resolves each token to a value that corresponds to the item, URL-encodes the value, and substitutes it in the template. If Microsoft 365 can't resolve a token, it omits that token from the resolved URL. The exceptions are `{tenant-id}` and `{drive-id}`—if Microsoft 365 can't resolve them, they remain as literal text in the URL.
+
+### Supported tokens
+
+| Token | Value your application receives |
+| --- | --- |
+| `{tenant-id}` | GUID of the consuming tenant. Used to make tenant-scoped Microsoft Graph API calls. |
+| `{drive-id}` | Drive ID of the container. Use it with Microsoft Graph APIs to reference the container. |
+| `{folder-id}` | Item ID of the file's immediate parent folder. Item IDs aren't GUIDs. If the file is at the root of the container, `{folder-id}` is omitted from the redirect URL rather than passed as an empty value. |
+| `{item-id}` | Item ID of the driveItem. Item IDs aren't GUIDs. |
+| `{site-domain}` | _To be documented._ |
+| `{list-id}` | _To be documented._ |
+| `{site-url}` | _To be documented._ |
+
+To use a custom container property as a token in `urlTemplate`, set the property's `isPatternToken` value to `true` when you create or update the property. Then reference the property in your template by enclosing its name in curly braces (for example, `{myCustomProperty}`). For more information, see [Add custom properties to a fileStorageContainer](/graph/api/filestoragecontainer-post-customproperty).
+
+#### Advanced tokens
+
+The following tokens cover specialized scenarios. Most applications can rely on the [common tokens](#supported-tokens) above.
+
+| Token | Value your application receives |
+| --- | --- |
+| `{ownershipType}` | _To be documented._ |
+| `{itemname-guid}` | _To be documented._ |
+| `{folderpath-guids}` | _To be documented._ |
+
+### Example
+
+If your container type has `urlTemplate` set to:
+
+```text
+https://app.contoso.com/open?t={tenant-id}&d={drive-id}&i={item-id}
+```
+
+When a user opens a `.txt` file from a search result, Microsoft 365 redirects the user to a URL like the following:
+
+```text
+https://app.contoso.com/open?t=72f988bf-86f1-41af-91ab-2d7cd011db47&d=b%21abc123def456ghi789jkl0&i=01ABC23DEF45GHI67JKL890
+```
+
+Your application receives the tenant ID, drive ID, and item ID as query parameter values (using the parameter names you defined in the template, such as `t`, `d`, and `i`). Use these values to retrieve and open the file through the Microsoft Graph API.
+
+### Update `urlTemplate` with Microsoft Graph
+
+Use the PATCH endpoint [Update fileStorageContainerType](/graph/api/filestoragecontainertype-update) to update `urlTemplate`:
+
+```http
+PATCH https://graph.microsoft.com/v1.0/storage/fileStorage/containerTypes/{containerTypeId}
+Content-Type: application/json
+
+{
+  "settings": {
+    "urlTemplate": "https://app.contoso.com/open?t={tenant-id}&d={drive-id}&i={item-id}"
+  }
+}
+```
+
+To clear `urlTemplate`, set the property to `null` in the PATCH request body.
+
+### Verify your configuration
+
+Because validation failures are silent, confirm your update by reading the value back. Call [Get fileStorageContainerType](/graph/api/filestoragecontainertype-get) with the `$select` query option to retrieve the current `urlTemplate` value:
+
+```http
+GET https://graph.microsoft.com/v1.0/storage/fileStorage/containerTypes/{containerTypeId}?$select=settings
+```
+
+If the response shows `urlTemplate` as `null`, the URL you submitted didn't meet the [requirements](#requirements). Update the value and try again.
+
+## What your application does when called
+
+When Microsoft 365 routes a user to your application, your application must:
+
+1. Authenticate the user. The user might not have an active session in your app. Microsoft 365 doesn't pass authentication context in the redirect URL.
+1. Parse the token values from the redirect URL query string.
+1. Call Microsoft Graph with the `driveId` and `itemId` to retrieve the [driveItem](/graph/api/resources/driveitem) and open the file in your application's UI.
+
+For information about calling Microsoft Graph against a consuming tenant's containers, see [Authentication and authorization](../auth.md).
+
+## Troubleshooting
+
+| Symptom | Possible cause |
+| --- | --- |
+| Your files don't appear in Microsoft 365 search results. | The container type's `isDiscoverabilityEnabled` setting is `false`, or the registration in the consuming tenant overrides the setting. Search indexing can also take time after enablement. |
+| Users land on the Microsoft help page instead of your application. | `urlTemplate` is `null` (likely because the URL failed validation), or the file type opens in a Microsoft 365 viewer instead of redirecting. |
+| A token appears as literal text (such as `{tenant-id}`) in the redirect URL. | Microsoft 365 couldn't resolve the token for the current item. Verify the token name matches a [supported token](#supported-tokens) or a custom property with `isPatternToken` set to `true`. |
+| Updates to `urlTemplate` don't appear in search results. | Search index updates aren't instantaneous. See [Limitations](#limitations). |
+
+## Limitations
+
+### Updates to `urlTemplate` aren't instantaneous
+
+Microsoft 365 stores the destination URL for each file in the search index. If you configure or update `urlTemplate` after files are indexed, search results continue to use the previous destination until Microsoft 365 updates the index. Updates to a container type's settings can take up to 24 hours to reach existing container type registrations.
+
+### `urlTemplate` is scoped to the container type
+
+The template applies to all container instances of the corresponding container type across all consuming tenants. Use the `{tenant-id}` token to route users to the correct tenant within your application.
