C2F order is a crypto-to-fiat API tool. Your clients can sell cryptocurrency from their account on your platform and receive payment to a bank card or via SEPA transfer.

Limits and rates

• Get fiat currency limits for the selected sale type (CARD or SEPA) by using the fiat withdrawal limit endpoint.
• Calculate the rate for selling cryptocurrency for fiat by using the fiat withdrawal rate endpoint.

Sell crypto with bank card or SEPA

• Create a request to sell cryptocurrency with CARD or SEPA type - card / sepa
• If the sale is successful, you will receive a webhook - FIAT_WITHDRAWAL_SUCCESS
• If the sale fails, you will receive a webhook - FIAT_WITHDRAWAL_ORDER_FAILED
• After receiving the webhook, we recommend checking the sale information by requesting order details - order
