Event and visitor functions require authentication to access some service providers, such as Facebook or Google. To add authentication to a function, you must have an account with the service provider. You can add authentication to a function in the Advanced tab of the Tealium Functions code editor.

When you add authentication to a function, an access token is generated and is displayed in the Advanced tab of the code editor. The function uses the access token to retrieve the authentication and pass it in an HTTP request for a service provider.

The steps for adding an authentication vary depending on the authentication selected. The following sections provide instructions for adding Facebook, Google, API Key, and UID 2.0 authentication. For information on adding OAUTH 2.0 authentication, see Adding OAuth 2.0 Authentication to an Event or Visitor Function.
