Vonage Voice API uses a concept of Applications for authenticating calls. An Application is a bundle of config such as keys and webhook URLs, and each application has a name.
When you start creating a Vonage Voice API Zap, you will be asked to connect your Vonage Voice API account.
You'll now be asked to provide your API key, API Secret, and the application name you want to use. You can find your API key and Secret on the main page of dashboard at https://dashboard.nexmo.com
Enter these along with the application name you want to use in the Zapier auth screen.
Vonage will then create a new application on your account and store the private keys. When you activate a Zap, the webhook url for this application will be updated and the number associated with the incoming call will be linked to the application.
NOTE: If you have multiple incoming call Zaps, each one must use a separate application config.
