FAQ
Does Luhn failure always mean the card is invalid?
Not always. Luhn failure often indicates format/check-digit issues, but final validity should be confirmed by the issuer or payment channel.
Why can the request fail?
Typical reasons include temporary network issues, service unavailability, or invalid input format. Check the number and retry.
