Common root causes

  • PIN entered with wrong length

Frequently Asked Questions

How do I recover invalid_pin?

Only at a card reader with the customer present. PIN errors require in-person correction and do not apply to online or recurring subscription billing.

Does invalid_pin affect online subscriptions?

FlyCode handles online subscription recovery and does not apply to PIN-based declines. Online recurring charges use card authorization, not PIN verification.
