Sample Verity Issuer App

This is a sample Issuer app which is using Verity REST API. For more information on this Sample Issuer app read this explanatory document

Requirements:

• You have received Verity application endpoint, Domain DID and REST API key from Evernym
• You have NodeJs v12 installed
• You have ngrok installed (https://ngrok.com/)

NOTE: The issuer application webhook endpoint (/webhook) needs to be served on a public URL so that Verity Application server can send messages to it. Ngrok is used here as a developer tool to provide a publicly available endpoint that tunnels to the local listening port of the Issuer App. If you have capabilities to start the Issuer application on a cloud infrastructure then you don't need to install and start ngrok - you just need to specify your URL address in the webhookUrl parameter (e.g. http://<your_cloud_ip>:4000/webhook)

To try out sample Issuer app follow these steps:

• In a separate terminal window start ngrok for port 4000 and leave it running :

ngrok http 4000

• Install required NodeJs packages:

npm install

• Change the values for verityUrl, domainDid, xApiKey, and webhookUrl with your values in the Issuer.js file:

const verityUrl = '<< PUT VERITY APPLICATION SERVER URL HERE >>' // address of Verity Application Server
const domainDid = '<< PUT DOMAIN DID HERE >>' // your Domain DID on the multi-tenant Verity Application Server
const xApiKey = '<< PUT X-API-KEY HERE >>' // REST API key associated with your Domain DID
const webhookUrl = '<< PUT WEBHOOK URL HERE >>' // public URL for the webhook endpoint

Sample values might look like this:

const verityUrl = 'https://vas.pps.evernym.com'
const domainDid = 'W1TWvjCTGzHGEgbzdh5U4b'
const xApiKey = 'AkdrCwUhNXiQi3zgwKw2KhR6muAX1Q18phP4cfuMtvq4:4cBQC9EsbMa9T96KA4noZwLJQuVcd6KBwaqFhRqZQKFWT45VEm3jbPCm8S6bqhwh3UKEKAPkHeLz9Gb1d1YE1dWv'
const webhookUrl = 'https://1326d835655f.ngrok.io/webhook'

• Start Issuer app

node Issuer.js
