**STEP 1**

**STEP 3**

Identity Number for a buyer may be a required field for the order process (new sale, upsell & recurring billing). Discuss this requirement with iyzico.

This is TCKN for Turkish merchants and passport number for foreign merchants

If using CheckoutChamp hosted pages:

* Put an input on the checkout page. Set Name = custom field 3. Make it a required field. Give it a label and/or placeholder sufficient for the buyer to enter Identity Number.

If not using CheckoutChamp hosted pages:

* Use any order custom field 1-5 to pass the buyer's Identity Number with the proper prefix followed by a pipe (IDCARD or PASSPORT). For example IDCARD|74300864791

**STEP 4**

If using Secure 3DS be sure the checkout page supports the challenge requests

[Direct API 3DS Instructions](/crm/gateway-setup/direct-api-3ds-instructions.md)

**STEP 5**

A transaction may be put in review if the fraud status is flagged as Review. To get the final disposition of the review a webhook must be enabled at iyzico. Put in a request to iyzico to send a webhook to **<https://api.checkoutchamp.com/billers/iyzico/notification/>**. You will need to share the Merchant ID on your iyzico dashboard with the iyzico team to get this enabled.
