Using the KYC plugin
Using Sumsub Plugin with React
Please note that the Sumsub app token needs to be generated by the Verified Network support team for any third party integration that uses the KYC/AML process of the Verified Network. Contact Verified Team on Discord: https://discord.com/invite/N5xYeePjmt The app tokens from Verified Team are needed to make request to Sumsub API to generate access token that the KYC plugin needs to work. To generate access token from Sumsub Api:
/** install ethers, axios and crypto-js: npm i ethers axios crypto-js **/
//Import ethers, axios e.t.c
import { ethers } from 'ethers';
import axios from 'axios';
import hmacSHA256 from 'crypto-js/hmac-sha256';
import hex from 'crypto-js/enc-hex';
const abiCoder = new ethers.utils.AbiCoder();
const userAddress = 'address of user for kyc';
const networkId = 'chain id(string) of network connected to';
const hashedAddress = abiCoder.encode(
["string", "string"],
[userAddress, networkId]
);
const userId = hashedAddress + Math.random().toString(36).substr(2, 9); //id verified uses
const baseUrl = 'https://api.sumsub.com'; //sumsub base url. note: without '/'
const secondUrl = `/resources/accessTokens?userId=${userId}&levelName=contact-details&ttlInSecs=1200`; //note: starts with '/'
const sumsubAppToken = 'your sumsub app token'; //contact Verified Network Team on Discord to get this
const sumsubSecretKey = 'your sumsub secret key'; //contact Verified Network Team on Discord to get this
const ts = Math.floor(Date.now() / 1000); //format current time
const hmacMessage = ts + "POST" + secondUrl; //combine ts, request method(POST) and second url
const signature = hmacSHA256(hmacMessage, sumsubSecretKey); //hash the message with sumsub secret key
//note: url = baseUrl + secondUrl;
//api url to use is 'https://api.sumsub.com/resources/accessTokens?userId=${userId}&levelName=contact-details&ttlInSecs=1200'
const generateSumsubAccessToken = async (url) => {
return await axios({
method: "POST",
url: url,
headers: {
Accept: "application/json",
"X-App-Token": sumsubAppToken,
"X-App-Access-Ts": ts,
"X-App-Access-Sig": hex.stringify(signature),
},
})
.then((res) => {
const response = res.data;
return response.token; //return access token
})
.catch((err) => {
//handle request error
console.error(`Post request to url: ${url} failed with error: ${err}`);
return;
});
};
const url = baseUrl + secondUrl;
const accessToken = await generateSumsubAccessToken(url);Access token above will be used with KYC plugin to handle users KYC Verifications
