Simple and reliable – that’s the payment gateway from the Czech Fio bank. Offer your customers the option to pay by card or digital wallets at checkout and accept payments in the most widely used world currencies and in 26 languages.
Integrating the Fio payment gateway into your WooCommerce store is easy. Let’s take a look at how to do it.
1. Applying for the Payment Gateway
The first step if you want to offer the Fio payment gateway in your online store is to sign a contract with Fio bank. Therefore, you must first apply for the payment gateway.
If you already have an account with Fio bank, simply request the payment gateway directly in your Internet Banking (New product > Request payment gateway/terminal).

If you are not yet a Fio bank client, you can complete an online application directly on the Fio bank website.

To apply for the payment gateway, you need to fill in identification, contact, and business details. In addition to the payment gateway, you can also apply for a payment terminal at the same time.
You can see how to apply for the payment gateway and terminal in the following video:
After your application is processed, the bank will contact you with a contract offer. Only after signing the contract can you proceed with connecting the payment gateway to your online store.
2. Connecting the Fio Payment Gateway with WooCommerce
After successfully signing the contract with the bank, it’s time to connect your store to the payment gateway. In WooCommerce, you can do this using the Toret Fio banka plugin without any programming knowledge. This plugin supports:
- online card payments
- Google Pay and Apple Pay digital wallet payments
- 4 currencies – CZK, EUR, USD, and GBP
- 25 languages
The plugin adds its own payment method to WooCommerce. This allows you to select shipping methods or countries for which the payment gateway will be active.
TIP: In addition to the payment gateway, this plugin also provides bank transfer payment verification and matching. Payments received in your Fio account no longer need to be manually checked – the plugin confirms paid orders for you. Learn more about payment matching >

Detailed documentation will help you with installation, setup, and testing of the plugin, or you can use the Convenient Plugin Installation service and have everything configured for you.
3. Testing
Before going live, you will receive access to a testing environment. There you will find the necessary documentation and guides, generate a test key for implementation, and obtain test payment credentials to perform transactions in your store. After completing the tests, contact the gateway provider again to request a review and activation of the live environment.
4. Going Live
After successful testing and subsequent approval, you will gain access to the production environment, receive a functional key, and your payment gateway will be activated. You can now start accepting payments from your customers.
As you can see, implementing the Fio bank payment gateway into your WooCommerce store is not complicated, and with the Fio banka plugin you can do it even without programming knowledge. Start offering your customers this reliable payment gateway today.
