How to implement the TikTok Login Kit for Web in PHP

has recently released their new API to allow Social Login via their platform. They called it .

With more Gen-Z and Millennials in the platform, allowing the simplified signup and login process via TikTok is the logical step for many Web Apps, including our very own .

While the implementation is a very basic oauth2 flow, there were no published class nor guides specific to PHP implementation, so I thought useful to publish an and this quick tutorial based on such class.

Step 2: Install helper class

Use Composer to install the PHP helper

composer require gimucco/tiktok-loginkit

If, for any reason, you’re not using Composer, you can download the class from . Current stable is v0.1.
