Next steps
When using Stripe's front ends, in most cases a soft decline from an issuer triggers an authentication flow, allowing the customer to try again and authenticate their card. In some cases, such as off-session payments, you might need to request the customer to retry. If the card issuer returns this decline code despite a successfully authenticated transaction, the customer needs to contact their card issuer for more information.
