**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

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

[Basic 3DS Instructions](/konnektive-crm/gateway-setup/basic-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.konnektive.com/billers/iyzico/notification/>**. You will need to share the Merchant ID on your iyzico dashboard with the iyzico team to get this enabled.
