Class LiffClient

Namespace
Line.OpenApi.Liff
Assembly
Line.OpenApi.Liff.dll

Facade for the LIFF management API. It wraps a single-host (api.line.me) Kiota client and provides the priority use case "list / add / update / delete LIFF apps" through thin convenience methods.

Unlike Messaging, there is no data-plane host, so no host override (BaseUrl) is needed and the generated default of api.line.me is used as-is. For lower-level operations, the generated builders are directly accessible via Api.

Design note (the intent behind the asymmetry with Messaging): LIFF is a small closed surface of 2 paths and 4 operations, so convenience methods can cover it completely. Messaging has many endpoints where complete coverage is impractical, so it exposes the generated builders directly. This difference is not an inconsistency but a decision scaled to the size of the surface.

Usage: var liff = LiffClient.CreateWithStaticToken("CHANNEL_ACCESS_TOKEN"); var apps = await liff.GetAppsAsync(); var added = await liff.AddAppAsync(new AddLiffAppRequest { /* ... / }); await liff.UpdateAppAsync(added!.LiffId!, new UpdateLiffAppRequest { / ... */ }); await liff.DeleteAppAsync(added.LiffId!);

Constructors

LiffClient(IAuthenticationProvider, HttpClient?) 

public LiffClient(IAuthenticationProvider authProvider, HttpClient? httpClient = null)

Parameters

authProvider IAuthenticationProvider

Authentication provider (static or refreshing, either works).

httpClient HttpClient

The HttpClient shared by the adapter. Supplied by IHttpClientFactory via DI (shared handler pool, Kiota default middleware applied). When null, the adapter creates its own default HttpClient (for quick use).

Properties

Api

The generated client (exposed for low-level operations).

public LiffApiClient Api { get; }

Property Value

LiffApiClient

Methods

CreateWithStaticToken(string)

Helper to quickly construct from a long-lived channel access token.

public static LiffClient CreateWithStaticToken(string channelAccessToken)

Parameters

channelAccessToken string

Returns

LiffClient

DeleteAppAsync(string, CancellationToken)

Deletes a LIFF app from the channel (DELETE /liff/v1/apps/{liffId}).

public Task DeleteAppAsync(string liffId, CancellationToken cancellationToken = default)

Parameters

liffId string
cancellationToken CancellationToken

Returns

Task

GetAppsAsync(CancellationToken)

Gets all LIFF apps registered on the channel (GET /liff/v1/apps).

public Task<GetAllLiffAppsResponse?> GetAppsAsync(CancellationToken cancellationToken = default)

Parameters

cancellationToken CancellationToken

Returns

Task<GetAllLiffAppsResponse>
