Signing In a User Automatically after Sign Up

This document guides you on adding automatic sign-in to a sign-up form so that a new user will be logged in right after account creation.

Prerequisites

To follow this tutorial, you must already have a working sign-up form, where a user can create a new account:
Creating a Sign-Up Form

Steps

Automatic sign-in after sign-up is a three-step process:

• Step 1: Add key to sign up form
• Step 2: Create GraphQL mutation
• Step 3: Create form

Step 1: Add the 'callback_actions' Key to Sign Up Form

In your form configuration, add the key at the end (order doesn't matter) of the YML definition.

app/forms/sign_up.liquid

This code snippet executes the query.

Step 2: Create 'user_session_create' GraphQL Mutation

This mutation takes two obligatory arguments: email and password – both strings.

app/graphql/user_session_create.graphql

This calls the with the same arguments you received from the .

Step 3: Create the 'session_create_form' Form

is supported by the server, so you don't need to define anything – the server will handle user credentials and authenticate the user.
