Check in system for conference attendees that prints a label

Description

I need a web based system that will allow me to check people into my conference and then print a name badge with a QR barcode.
The system will require a lookup function either via a scanner or via a surname lockup.
The data will be pulled via an API from our ticket provider, tito. API details can be found here https://ti.to/docs/api/checkin#introduction
The API is a REST API and returns JSON responses.
The label will feature the persons name, company name and attendee level (attendee, speaker, VIP etc) The label will also feature a Qr barcode that will be a unique identifier that can be scanned.
