Ticket link from the app without SSO login requires rate limiting. We have no possibility to ratelimit our API endpoint as it is called from your backend, to prevent a brute-force attack. Misuse of the endpoint can lead to a potential ticket barcode leak. If you want to use this endpoint, you have to do the rate limiting on your end. Other integrations allow the user to enter a phone number or email and send them an OTP so they can perform rate limiting on that.
