TikTok Login Kit iOS Integration Guide
TikTok's developer documentation provides a step-by-step guide to integrating Login Kit for iOS. After a user authenticates via TikTok, apps can access basic profile data (display name, avatar); access to additional user data requires approval on the TikTok for Developers portal. The guide details prerequisites (obtaining client_key and client_secret, registering an https universal link redirect URI and enabling associated domains), importing the TikTokOpenAuthSDK, creating a TikTokAuthRequest with scopes and redirectURI, sending the request and handling the asynchronous TikTokAuthResponse. It instructs server-side exchange of the authorization code and PKCE codeVerifier for a user access token and points developers to separate pages for user access token management and error handling.
Official TikTok developer documentation from a major social platform details iOS authentication flows and PKCE-based token exchange — relevant to app developers, identity infrastructure and any ad/marketing integrations relying on authenticated user data.

Key Takeaways & Evidence Grounding
- TikTok provides a Login Kit for iOS that allows apps to authenticate users and access basic user data (display name and avatar).
- Developers must obtain client_key and client_secret from the TikTok for Developers app credentials and add the Login Kit product on their app page.
- A registered redirect URI must be a universal link with an https scheme, and the iOS app must support associated domains.
- Integration uses the TikTokOpenAuthSDK and TikTokAuthRequest (set scopes and redirectURI) and receives authorization responses via a TikTokAuthResponse callback.
- To obtain an access token, apps must upload the returned auth code and the PKCE codeVerifier to a server-side endpoint; additional user data access requires TikTok approval.

TikTok Login Kit for iOS (Swift)
TikTok's developer documentation explains how to integrate Login Kit on iOS using Swift. Developers must obtain a client key and client secret from the Developer Portal, create a TikTokOpenSDKAuthRequest, set requested OAuth scopes (for example user.info.basic and video.list), and send the authorization request. On successful authorization the SDK returns a code which should be uploaded to a backend server and exchanged for a user access token. The guide notes additional scopes may require TikTok approval and points developers to error-code and token management references.
TikTok Login Kit iOS Objective-C Guide
TikTok published a developer guide showing how to integrate Login Kit on iOS using Objective-C. The guide explains prerequisites (obtain a client key and client secret from the Developer Portal), how to create and send a TikTokOpenSDKAuthRequest with requested OAuth scopes (for example user.info.basic and video.list), and how to handle the authorization response. Successful authorization returns an authorization code that must be uploaded to a backend server and exchanged for a user access token. The documentation notes that additional scopes may require TikTok approval and refers developers to error-code and token-management references for debugging and lifecycle handling.
TikTok Login Kit Android Quickstart
TikTok's developer documentation for Login Kit on Android (Kotlin) provides step-by-step instructions to integrate OAuth-based authentication into Android apps. Updated August 19, 2026, the guide explains obtaining client credentials from the TikTok for Developers console, adding the Login Kit product, creating an AuthApi and AuthRequest, and invoking authorize(). It covers required parameters (clientKey, scope, redirectUri, codeVerifier), receiving callbacks via Android intent filters, parsing the auth response, uploading the auth code to a server to exchange for a user access token (PKCE flow), and links to further pages on scopes, token management, and error handling. Basic profile access (display name, avatar) is available; additional scopes require approval.
