Data Collection & Login

The Data Collection & Login feature adds a login and registration flow to your Game Center. This allows you to identify returning users and collect player data in one place.

You can also customize the appearance and text used in the login and registration flow.



Choose a player identifier

The most important setting in this section is the Player Identifier. This determines how users are identified when they return to the Game Center. Two identifier types are available.

User input

Players enter their information through a form.You can select which parameters to collect by adding them in the + Add Parameters section. These fields determine what information players need to provide during registration.

URL parameter

Players are identified through values passed in the Game Center URL.Example:https://your-game-url.com?{parameter}={your_value}

This method is commonly used when integrating the Game Center with external systems.

For additional security, you can use Authenticated UUID, which requires a signed JWT (JSON Web Token) containing the player’s UUID.

Add data collection parameters

You can define additional parameters to collect more information from users.

  1. Click + Add Parameters.
  2. Select whether the parameter should come from User Input or a URL Parameter.
  3. Choose the parameter type from the dropdown.

If you select User Input, make sure the Input Field Text clearly describes the information the player should provide.
If you have created custom parameters in Brand Settings, they will also be available in this list.

 

Recommendation

To avoid asking players to fill in multiple forms, it is recommended to collect player data only in the Game Center login flow.
If you do this, you do not need to enable Data Collection in individual games.

Customize the login flow

You can adjust the visual style and text used in the login and registration process.

Available options include:

  • Login text and instructions
  • Terms and conditions text
  • Text color
  • Background color
  • Logo

All login and registration texts can be edited in the Login Text section.

Login emails

You can configure the emails sent during the login process, such as verification emails.
These emails will use the styling defined in the Email Design section or your Assets & Settings configuration.
