For more information about custom signup and login prompts, read Customize Signup and Login Prompts.

​
Setup

In your , set up Universal Login, Identifier First Authentication, and a Database Connection that uses passwords. Run Auth0’s single-page ACUL boilerplate application by executing the code below, which provides additional context for Advanced Customizations interfaces. 
git clone https://github.com/auth0/auth0-acul-react-boilerplate
After cloning the boilerplate app, change the directory to the auth0-acul-react-boilerplate folder and install the Advanced Customizations SDK. 
#Clone the ACUL sample application into the root folder of your project

git clone https://github.com/auth0-samples/auth0-acul-samples.git

#Change directory to install the ACUL sample application 

cd auth0-acul-samples && npm i

Build the signup-id screen

Complete the Build Identifier First Signup with Password guide.

​
Add a custom prompt field

In your Signup ID index.tsx file, add the following code: accordion.expand_all/accordion.collapse_all 
export const SignupIdScreen = () => {
  const signupManager = new SignupId();
  const [firstName, setfirstName] = useState('');
  ...

  return (
    <div>
      ...
      ...
      // Custom input
	  <input
		type="text"
        name="ulp-firstName"
        placeholder="Enter your name"
        value={firstName}
        onChange={(e) => setfirstName(e.target.value)}
        className="w-full px-3 py-2 border border-gray-300 rounded-md shadow-sm placeholder-gray-400 focus:outline-none focus:ring-2 focus:ring-blue-500 focus:border-blue-500"
      />
      // Pass the input value to the login payload
      <button 
          className="w-full flex justify-center py-2 px-4 border border-transparent rounded-md shadow-sm text-sm font-medium text-black bg-blue-600 hover:bg-blue-700 focus:outline-none focus:ring-2 focus:ring-offset-2 focus:ring-blue-500"
          onClick={() => signupManager.login({ email: email, 'ulp-firstname':  firstName})}
        >
          Continue
      </button>
      ...
      ...
    </div>
  );
};

export default SignupIdScreen;
The signup-id POST payload now includes ulp-firstName.

​
Validate and save your captured data

exports.onExecutePreUserRegistration = async (event, api) => {
  const firstName = event.request.body['ulp-firstName'];

    return;
  }

  api.user.setUserMetadata("firstName", firstName);
};
