Instructions

Configuration

:::tip An application can be created at https://your-fusionauth-server-url/admin/application.

For more information, follow the FusionAuth 5-minute setup guide. :::

In the OAuth settings for your application, configure the following.

• Redirect URL
  • http://localhost:3000/api/auth/callback/fusionauth
• Enabled grants
  • Make sure Authorization Code is enabled.

If using JSON Web Tokens, you need to make sure the signing algorithm is RS256, you can create an RS256 key pair by going to Settings, Key Master, generate RSA and choosing SHA-256 as algorithm. After that, go to the JWT settings of your application and select this key as Access Token signing key and Id Token signing key.
