Using you can put extra information into the user profile's programmatically. This is useful for where making your current customer data better by adding more details from outside sources.

Here are easy steps to achieve this:

Step 1. Make sure that you have an Authgear account. If you don't have one, you can on the Authgear website. Start by logging into your .

Step 2. Go to User Profile → Custom Attributes page.

Step 3. Add 3 new attributes there, namely city, name, and timezone:

Step 4. Navigate to your Authgear Dashboard's Advanced->Hooks section.

Step 5. Add a new Blocking Event.

Step 6. Choose the Block Hook Type as the TypeScript and set the Event option to User pre-create. You will write a new Typescript function from scratch.

Step 7. Click on Edit Script under the Config option.

Step 8. Write a function logic for how you integrate any external API to populate custom attributes into the editor. For example.

		
export default async function(e: EventUserPreCreate): Promise
			 {
  // API Key for IP Geolocation
  const apiKey = 'MY_API_KEY';
  // Any random IP address
	const ipAddress = '8.8.8.8' 

  // Fetch data from the IP Geolocation API
  const response = await fetch(`https://api.ipgeolocation.io/ipgeo?apiKey=${apiKey}&ip=${ipAddress}`);
  const data = await response.json();

return {
    is_allowed: true,
    mutations:{
      user: {
          custom_attributes: {
            "city": data.city, 
            "country": data.country_name,
            "timezone": data.time_zone.name
        }
      }
    },
  };
}

Step 9. Now if you navigate to User Management and Add a new user.

Step 10. After the user is created, you should able to see custom attributes values have been updated for the user:
