Which UI do you use?

Custom UI

Pre built UI

Post signin / signup callbacks

1) On the frontend

ReactJS

This method allows you to fire events immediately after a successful sign in. For example to send analytics events post sign in.

// this goes in the auth route config of your frontend app (once the pre built UI script has been loaded)

2) On the backend

For this, you'll have to override the consumeCode and signInUp recipe functions in the init function call.

NodeJS

Important

For other backend frameworks, you can follow our guide on how to spin up a separate server configured with the SuperTokens backend SDK to authenticate requests and issue session tokens.

Using the code above, if createdNewUser is true, you can (for example):

• Add the user's ID and their info to your own database (in addition to it being stored in SuperTokens).
• Send analytics events about a sign up.
• Send a welcome email to the user.
• You can associate a role to the user.
