Let us assume that we have an app contact finder. Now, Our goal is to demonstrate the capability of the VoiceWorx platform to integrate with external platforms and perform CRUD operations against them via web API calls with support for MFA. In this Alexa Skill it is called “Contact Finder”. This Alexa app will look up and return a person’s number that is stored in the contacts database and is accessible via the contacts API endpoints in demo.voiceworx.ai. The skill will be protected via a pin code sent to the users that invoked the skill’s phone and email. The MFA prevents unauthorized personnel from accessing the information provided by the skill. When a contact is asked and user has not authenticated with a PIN code, a 4-digit code is sent to the users email and phone number. When the correct pin code is provided by the user while interacting with the skill, access is granted but the PIN code is valid for five minutes. If a user does not interact with the skill within 5 minutes, on next interaction, a PIN code is regenerated and resent to the users email and phone number.
