How to create new user in Authy by scanning QR code in my application?

Question

I have my java application with spring boot and angular in UI.

I wanted to create a new user in Authy by QR code scanning from Authy mobile app. I have generated the QR code as per the steps in below document links. But in the end, I got an error while scanning it from the Authy mobile app - "Contact to your service provider Error".

https://www.twilio.com/docs/authy/api/users#add-a-user-without-providing-email-or-phone-number

I have generated the QR code base64 token using JWT as per documents. Then I have sued the online QR generator to show the QR code.

Please help me out with this. It will be helpful if you let me know the steps or anything I got missed in my flow.

Thank you in advance!!

In order to get the camera to read the QR code, it needs to be in the form of a URL. You have created your token (though it seems to be missing the signature in your example in the comments), so you need to form a URL like this:

authy://account?token={token}

and then encode that as a QR code. Then the app will be able to pick it up and start generating 2FA codes.
