Version​

This documentation is for the UID2 GMA Plugin for Android version 1.6.0 and later.

Complete UID2 Account Setup and Configure Account​

To integrate with UID2, you'll need to have a UID2 account. If you haven't yet created an account, first follow the steps described on the Account Setup page.

When initial account setup is complete, you'll receive instructions and a link to access the UID2 Portal, where you can create your credentials for the production environment and configure additional values, if needed. For details, see Getting Started with the UID2 Portal.

The steps you'll take in the UID2 Portal are different depending on whether your implementation will be client-side, client-server, or server-side. Specific instructions are in each implementation guide. For a summary, see Client-Side or Client-Server Integration?.
