What is email fallback verification?
A backup system (PHP 8.1+) that checks Redsys confirmation emails every 5 minutes. If an order should be marked as paid but was not — due to an IPN failure — the plugin catches it and updates the order status automatically. It virtually eliminates orders stuck as "pending payment".
How does it work?
- Configure the email account that receives Redsys payment confirmations.
- Every 5 minutes, the plugin checks for new confirmation emails.
- If it finds one for an unpaid order, it marks the order as paid.
Benefits for store owners
- Virtually eliminates orders stuck as "pending payment"
- Triple security: IPN + URL params + email
- Catches network failures and server timeouts
- Automatic, with no manual intervention needed
Requirements
- PHP 8.1 or higher
- Access to the email account receiving Redsys confirmations
- WordPress cron running every 5 minutes
