# UpdateParticipantAuthentication
<a name="API_UpdateParticipantAuthentication"></a>

Instructs Amazon Connect to resume the authentication process. The subsequent actions depend on the request body contents:
+  **If a code is provided**: Connect retrieves the identity information from Amazon Cognito and imports it into Connect Customer Profiles.
+  **If an error is provided**: The error branch of the Authenticate Customer block is executed.

**Note**  
The API returns a success response to acknowledge the request. However, the interaction and exchange of identity information occur asynchronously after the response is returned.
