Third-Party Services
This plugin connects to the TAFI API, a service provided by TAFI Tech, to process Buy Now, Pay Later (BNPL) payments.
When a customer selects TAFI as their payment method at checkout, the following data is sent to the TAFI API:
- Merchant ID (idComercio)
- Customer phone number (celular)
- Order total amount (valor)
- Order description (descripcion)
- Branch name (sucursal)
- Salesperson name (vendedor)
- Transaction ID (idTransaccion)
TAFI sends payment confirmation notifications back to your store via webhook when the customer accepts or rejects the payment in WhatsApp. The webhook includes: idTransaccion, numeroAutorizacion, valor, creditoFirmado and descripcionError.

Changelog
1.1.0
- Thank-you confirmation block now renders above the order summary so the customer sees the WhatsApp flow first
- New modal pop-up that announces the final state (approved, rejected, expired) on top of the page
- Fixed reconciliation bug: status checks now mark the order as paid as soon as the customer signs in WhatsApp (estadoCredito “Aceptado” with creditoFirmado true), matching the webhook behaviour
- Added a “Consultar estado en TAFI” button in the order admin screen so merchants can manually trigger an API check when the customer’s tab closed before polling resolved
- Manual status-check action is now available on any TAFI order, not only those still pending
- Background safety-net: when an admin loads the dashboard, the plugin sweeps TAFI orders stuck in “pending” for 5+ minutes and reconciles them against the TAFI API. Throttled to one sweep every two minutes. Runs independently of wp-cron so it works even on sites where scheduled tasks are unreliable.
