Bancontact

Bancontact is the most popular online payment method in Belgium, with over 15 million cards in circulation. Customers use a Bancontact card or mobile app linked to a Belgian bank account to make online payments that are secure, guaranteed, and confirmed immediately.

In order to pay with Bancontact, customers are redirected to the Bancontact website or mobile app to authorize the payment and then return to your website where there is an immediate notification about the success or failure of the payment.

Step 1. Make a transaction request

From your server, make a POST /payment_preauthorize request.

POST https://sandbox.payabl.com/pay/backoffice/payment_preauthorize

Include in request:

• merchantid: The merchant identification number.
• orderid: The field orderid is optional and exclusively for the merchant's convenience.
• amount: The amount field contains the transaction’s total amount. This is the amount that will be transmitted to the authorizing system.
• currency: The currency field contains the alphanumeric currency code for the transaction, according to ISO 4217, e.g. EUR.
• payment_method: The payment method id - 5.
• signature: The signature field contains a 40-figure hexadecimal value. This signature value is a checksum designed to protect the merchant account from unauthorized access.
• bankcountry: Customer country in ISO Alpha-2 format: BE.
• email: The customer's email address.
• custom2: The name of payment method - bcmc.
  You can see a full list of parameters in Pre-Authorization.

Refunds

Bancontact supports refunds and can be initiated only on a successful captured transaction.
The request will send a credit note to the authorization system after the customer has already been charged. The refund amount will be credited to the customer and the merchant’s account will be charged.

The refund can be done in two ways:

• Through API integration
• Through payabl. dashboard

If you have API integration, you can check more in our documentation Refund.
