Activate API Key and HMAC Authentication

You can activate the plugin API Key and HMAC Authentication (com.glide.tokenbased_auth) in your ServiceNow® instance.

Before you begin

Procedure

  1. Navigate to All > System Applications > All Available Applications > All.

  2. Find the API Key and HMAC Authentication plugin (com.glide.tokenbased_auth) using the filter criteria and search bar.

    You can search for the plugin by its name or ID. If you cannot find a plugin, you might have to request it from ServiceNow personnel.

  3. Select Install to start the installation process.

    Note: When domain separation and delegated admin are enabled in an instance, the administrative user must be in the global domain. Otherwise, the following error appears: Application installation is unavailable because another operation is running: Plugin Activation for <plugin name>.

    You will see a message after installation is completed. For information about the components installed with a plugin, see Find components installed with an application.
