Initialize Protected Bank Transfer

For activating protected bank transfer in sandbox environment please send an email to integration@iyzico.com.

After activation is completed, sending "create checkout form" request will be enough to get a link or checkoutForm content.

The response contains below parameters

paymentPageUrl: This value can be assigned to a link/button or a div etc. It redirects customers to protected bank transfer page. This screen requests an email and mobile number(if you send these parameters at the time of init request, they appear as predefined). Customer selects the bank and clicks continue button. At this time, iyzico sends an informative email and sms(Price, IBAN, reference number) to the customer. Also a transaction is created on iyzico side. Because there is no payment yet,the status of payment is marked as init_bank_transfer(means that the payment is not completed yet). The bank transfer interface shows a complete transaction button. As soon as it is clicked, customer returns back an URL given by merchant at the time of init bank transfer request.

checkoutFormContent: This value contains a javascript code that loads iyzico checkout form elements to your web page. The checkout form will appear in the place where you add the mentioned "div" elements below. Checkout form contains a tab named "Protected Bank Transfer". As soon as it is clicked, the bank transfer interface appears and it asks customer an email and mobile number(if you send these parameters at the time of init request, they appear as predefined). Customer selects the bank and clicks continue button. At this time, iyzico sends an informative email and sms(Price, IBAN, reference number) to the customer. Also a transaction is created on iyzico side. Because there is no payment yet,the status of payment is marked as init_bank_transfer(means that the payment is not completed yet). The bank transfer interface shows a complete transaction button. As soon as it is clicked, customer returns back an URL given by merchant at the time of init bank transfer request.

Responsive usage

<div id="iyzipay-checkout-form" class="responsive"></div>

Pop-up usage

<div id="iyzipay-checkout-form" class="popup"></div>

After redirection to callBackUrl, you can show a message like "Order has been received" to your customers.

It is important for your customers to pay attention below points

iyzico reference number should be entered to description field while making bank transfer.
Customers should consider possible expenses for bank transfer and add the expense to the actual transfer amount. Transfer expense is between the bank and the customer. iyzico is not a part of these expenses. It is completely up to customer and his/her bank.
If customer sends more or less than the actual amount of order, the transaction will fail and the transfer will be refunded to the customer.
Transfers can be done within 3 days.

iyzico checks every transaction in every 15 minutes. If a bank transfer matches with a transaction, the status of transaction is changed to SUCCESS. iyzico informs the merchant and customer that the payment is successful. In addition, a notification is sent to webhookURL.
