### Steps

The iyzico marketplace solution primarily encompasses the collection and settlement processes. The integration involves three key steps, as outlined below:

1. [Submerchant](/en/products/marketplace/marketplace-implementation/submerchant.md)
2. [Online Payment](/en/products/marketplace/marketplace-implementation/online-payment.md)
3. [Approval](/en/products/marketplace/marketplace-implementation/approval.md)

To facilitate fund transfers to sellers (submerchants), it is necessary to register these sellers with iyzico API through a one-time registration process. Upon registering the submerchant seller with iyzico, the merchant receives a unique **subMerchantKey** in the response.&#x20;

During the payment process, the corresponding **subMerchantKey** for each product's seller in the shopping cart must be provided, along with the specific amount to be transferred to the seller (**subMerchantPrice**).
