Verify Silent Network Auth Sample Backend

These functions show you how to create and check verification tokens for Twilio Verify using the Silent Network Auth channel.

How to use the template

The best way to use the Function templates is through the Twilio CLI as described below. If you'd like to use the template without the Twilio CLI, check out our usage docs.

Pre-requisites

• Create a Verify Service
• Create a Sync Service. You can also use the Default Service in your Twilio Console account.
• Create a Map in your Sync service.

Environment variables

This project requires some environment variables to be set. To keep your tokens and secrets secure, make sure to not commit the .env file in git. When setting up the project with twilio serverless:init ... the Twilio CLI will create a .gitignore file that excludes .env from the version history.

In your .env file, set the following values:

Variable	Meaning	Required
ACCOUNT_SID	Find in the console	Yes
AUTH_TOKEN	Find in the console	Yes
VERIFY_SERVICE_SID	Create one here	Yes
SYNC_SERVICE_SID	Create one here	Yes
SYNC_MAP_SID	Create one here	Yes
