Login

The following sample will show you how to make a simple connection handler. First, we will generate a QR Code that will be the entry point by which users can interact with your dApp. Once scanned, the account details are forwarded to you.

Prerequisites:

Getting started

Generate a QR Code

In order to generate a QR Code you need to pass a Webhook to the generateQRCode method. This Webhook will be called every time a new user scan the QR Code.

You can set the scope in the params to fetch the NFT during the login process.

/* Define the scope */
$scope = ['profile', 'nft'];
/* Define a Webhook */
$webhookUrl = '';
/* Define a uniq Id that identify the browser */
$uniqId = '';

/* Generate the QR Code */
$qrCode = $client->generateQRCode($scope, $uniqId, $webhookUrl);
