  • Why do I see “iyzico” on my card statement?

    The reason why you see “iyzico” on your statement is that the online shop where you made your purchase uses iyzico’s technology. As iyzico, we never process any purchase or make any money transaction without your knowledge.

  • How can I change my IBAN?

    To update your bank details, please share a card statement that shows your new details via the email address you registered to iyzico. If you use Internet Banking, you need to share a screenshot showing those details.

  • When will the link I set up be approved?

    We have a 24-hour approval period for the very first link you set up through Link Management. Your products will be ready to receive payments within 24 hours upon the evaluation of our decision team.

  • How can I change my e-mail address?

    You can change your e-mail address following the steps below through your iyzico Control Panel:

    When you go to “iyzico Panel”>”Settings”>”Profile”>”E-Mail Settings”:

    1-) Enter the new e-mail address twice.

    3-) A verification code will be sent to your registered mobile number.
    4-) You can update your e-mail address by entering the verification code on the screen.

  • Should I make any additional payments regarding the commission fee invoice I receive?

    Your iyzico commission rate is deducted from the successful transactions before the payout. The invoice of the commission and transaction fees charged will be sent to your registered e-mail address in the first week of the following month. Therefore, you don’t need to make any additional payments.

  • My customer demands a refund, can you carry out the refund transaction?

    We are not able to interfere to the completed transactions due to account security. However, you can refund the relevant amount through the “Transactions” section.

  • What is general denial error?

    Errors with codes 57, 12, and 05 are the most frequent errors in e-commerce.

  • Is my customer charged in transactions where it says, “3D is initiated” or “3D is returned to merchant”?

    There are different status conditions on the iyzico Control Panel denoted with 4 different colors. Transactions shown in green express that the transaction is completed successfully.

    Transactions in red signify that the transaction was not completed due to an error. You will find information under the section titled “Error Message” on the reason of the error.

    Transactions in yellow (3D returned to merchant) express that the 3D secure code is entered, however, due to an error in the card (pin error, etc.), the transactions were unsuccessful.

    Transactions in orange (3D initiated) means that the customer progressed to the 3D page but the 3D screen was closed by the customer before the transaction was completed.

    You can check all your transactions according to the above guideline.

  • How can I do partial refunds?

    Under the “Transactions” sections of your iyzico Control Panel click on the payment number of the transaction you would like to cancel, or refund and it will direct you to a new page.

  • Can I use the same API key on my second website?

    Since your iyzico membership and payment method is specific to the domain stated in your membership agreement, you will need to make a new application for your second e-commerce site with a different e-mail address.
