![](/files/-MYOhFjPgMKV_rnn8CxL)

Integrating your exchange with a bank service is necessary for handling deposits and withdrawals of fiat currencies. This page will give step-by-step instructions on how to securely integrate a bank to your HollaEx Exchange.

{% hint style="warning" %}
The integration for payment services will differ depending on which payment service is used. This page is meant to be a general tutorial for bank integration. You will have to change the code depending on which service you use but the overall flow should remain the same. It's important to follow the flow for security purposes.
