+
+## Configuration
+
+https://developers.tiktok.com/doc/getting-started-create-an-app/
+
+## Options
+
+The **TikTok Provider** comes with a set of default options:
+
+- [TikTok Provider options](https://github.com/nextauthjs/next-auth/blob/main/packages/next-auth/src/providers/tiktok.js)
+
+You can override any of the options to suit your own use case.
+
+:::note
+TikTok requires that a `redirect_uri` param is sent. This must be configured to use the full URL, including protocol, domain, port and path to your Sign In API (default path for Auth.js is `api/auth/signin`). It should look something like `https://mydomain.com/api/auth/signin`.
+:::
+
+## Example
+
+```js
+import TikTokProvider from "next-auth/providers/tiktok";
+...
+providers: [
+  TikTokProvider({
+    clientId: process.env.TIKTOK_CLIENT_KEY,
+    clientSecret: process.env.TIKTOK_CLIENT_SECRET
+    redirect_uri: "https://mydomain.com/api/auth/signin"
+  })
+]
+...
+```
