Atlassian

1. Sign in to your Atlassian account and go to the [Atlassian Developer Console](https://developer.atlassian.com/console/myapps/)
2. Click "Create new app"
3. Fill out the app details
4. Configure your redirect URI (e.g., `https://yourdomain.com/api/auth/callback/atlassian`)
5. Note your Client ID and Client Secret

<Callout type="info">
  * The default scope is `read:jira-user` and `offline_access`. For additional scopes, refer to the [Atlassian OAuth documentation](https://developer.atlassian.com/cloud/confluence/oauth-2-3lo-apps/).
</Callout>

Make sure to set the redirect URI to match your application's callback URL. If you change the base path of the auth routes, you should update the redirect URI accordingly.

To configure the provider, you need to import the provider and pass it to the `socialProviders` option of the auth instance.

```ts title="auth.ts"
import { betterAuth } from "better-auth"

export const auth = betterAuth({
    socialProviders: {
        atlassian: { // [!code highlight]
            clientId: process.env.ATLASSIAN_CLIENT_ID as string, // [!code highlight]
            clientSecret: process.env.ATLASSIAN_CLIENT_SECRET as string, // [!code highlight]
        }, // [!code highlight]
    },
})
```

To sign in with Atlassian, you can use the `signIn.social` function provided by the client. The `signIn` function takes an object with the following properties:

* `provider`: The provider to use. It should be set to `atlassian`.

```ts title="auth-client.ts"
import { createAuthClient } from "better-auth/client"
const authClient =  createAuthClient()

const signIn = async () => {
    const data = await authClient.signIn.social({
        provider: "atlassian"
    })
}
```
