Class Parampos

Pre-authorization without 3D Secure (TP_Islem_Odeme_OnProv_WMD, NS). Blocks the amount; charge it with capture() or release it with voidAuthorization().

BIN query (BIN_SanalPos)

The amount to charge (paidPrice, Param's Toplam_Tutar) for a card and installment count, using the merchant's rates.

Cancel (void) a same-day payment. paymentId is the order id (Siparis_ID). Param requires the full amount; when price is not given it is read with a status query first.

Capture of a pre-authorization (TP_Islem_Odeme_OnProv_Kapa). amount may be lower than the authorized amount (partial capture).

Complete 3D Secure payment

1. Verifies islemHash with the configured GUID (callback values are untrusted).
2. Requires mdStatus = 1 (full 3D authentication).
3. Finalizes the payment with TP_WMD_Pay. The payment is only successful when TP_WMD_Pay returns Sonuc > 0 and a Dekont_ID.

Direct (non-3D) payment

price is Islem_Tutar and paidPrice is Toplam_Tutar (amount charged to the card, including any installment commission). For installments, calculate paidPrice from the rates configured on your Param account.

The merchant's customer-facing commission rates per card program (TP_Ozel_Oran_SK_Liste). Negative rates mean "not available" and are left out.

Payment status by order id (Siparis_ID)

3D Secure pre-authorization (TP_Islem_Odeme_OnProv_WMD, 3D). The bank posts to callbackUrl; completeThreeDSPayment() verifies it and finalizes with TP_WMD_Pay.

Initialize 3D Secure payment (TP_WMD_UCD, Islem_Guvenlik_Tip = 3D)

Render threeDSHtmlContent in the browser. Param POSTs the result to callbackUrl; pass that POST body to completeThreeDSPayment().

Installment options for a card with Param's totals (Toplam_Tutar = price + price × rate / 100).

Refund (full or partial). paymentId is the order id (Siparis_ID).

Releases a pre-authorization (TP_Islem_Iptal_OnProv); nothing is charged
