# Sample Configuration File

The following sample configuration contains the features that are configured in the Enhanced Chat API setup. Salesforce uses the configuration to validate the request.

The configuration is returned in the context.configuration field when you [Generate an Access Token](/docs/service/messaging-api/references/miaw-api-reference?meta=generateAccessTokenForAuthenticatedUser), and when you [Generate an Access Token for an Unauthenticated User](/docs/service/messaging-api/references/miaw-api-reference?meta=generateAccessTokenForUnauthenticatedUser).

You can also use the configuration to see which features are configured and determine the dynamic behavior of the client UI.
