Retrieve the Root CA Certificate Using a REST API Request {#semi-integrated-ad-app-retrieve-rootca-cert-task}
=============================================================================================================

You can use a REST API request to retrieve the Acceptance Devices app server's Root CA certificate when the app is operating in Local mode. You would then add the certificate to your trust store.  
You must authenticate each API request you send to a `Visa Acceptance Solutions` API by using a REST shared secret key or a REST certificate. For more information about authentication requirements, see the [*Getting Started with REST Developer Guide*](https://developer.visaacceptance.com/docs/vas/en-us/platform/developer/all/rest/rest-getting-started/restgs-intro.md "").
