Walley Checkout for WooCommerce was previously known as Collector Checkout for WooCommerce and there may be some remnants of this in the documentation or plugin. For instance in the code snippets and/or some of the settings.

Walley Checkout for WooCommerce is a plugin that extends WooCommerce, allowing you to take payments via Walley.

Limitations in functionality

Walley Checkout is an embedded checkout, a checkout solution that replaces the standard WooCommerce checkout form. This setup provides an easy way for the customer to complete the purchase and a convenient way for the merchant to offer multiple payment options in the same solution.

An embedded checkout also implies certain limitations in functionality. Compatibility with other plugins that extend the functionality of the standard checkout might be limited. Examples of features that might not work out of the box:

  • Selection of Delivery Date.
  • Extra checkout fields (besides the standard billing and shipping fields).
  • Newsletter subscription signup.
  • Create an account during checkout process where the customer gets the opportunity to select user name and password (however, this can be generated automatically in WooCommerce).


The plugin itself has no limitations regarding currency.

However, please note that there can be limitations in the agreement you have with Walley.

When it comes to questions regarding supported currencies you should always talk to your payment provider. The exception is when the plugin in fact do have limitations.

You can read more about this at the Walley website.

Checkout process flow in the plugin

Since Walley Checkout is an embedded checkout solution, order/cart data & customer data is passed between WooCommerce and the payment service provider in a different way than a payment method in the standard WooCommerce checkout.The checkout process looks like this:

  1. The checkout page is requested.
  2. If Walley Checkout is the default (or selected) payment method a request containing merchant and cart data is sent to Walley.
  3. Walley respond with information about a new transaction session.
  4. The checkout page is rendered and the Walley checkout iframe is displayed.
  5. The customer identifies herself in Walleys Checkout.
  6. A javascript event is triggered so that:
    – The checkout is paused.
    – Customer address data (country and postal number) is fetched from Walley.
    – If needed the cart is recalculated and an cart update is sent to Walley.
    – The checkout is resumed.
  7. When the customer clicks the Pay button in Walley Checkout iframe, the checkout page is being reloaded, the WooCommerce checkout form is being populated with customer address data and the form is then posted.
  8. An order is created in WooCommerce.
  9. Order status is changed to Processing (by triggering the WooCommerce function payment_complete()) and an email about the new order is sent to the customer.

Order management

When an order is created in WooCommerce and a reservation number exists in Walleys system, you have the possibility to handle the order management in Walley directly from WooCommerce. This way you can save time and don’t have to work in both systems simultaneously.

Read more about order management in Walleys system directly from WooCommerce in the Walley Checkout Order management documentation.

Customize the checkout page

In some scenarios there might be a need for modifying the checkout page. Learn more how you can Customize the Walley checkout page here.

Compatibility with themes & plugins

  • Walley Checkout uses its own template file for displaying the checkout page and should work with most themes. However, the plugin is only tested with the Storefront theme and we do not guarantee that it will work with other themes. Common situations when errors occur are:
    – Themes/plugins with customized template files for WooCommerce checkout page.
    – Themes/plugins that modifies the checkout into a multi step checkout.

Krokedil and Walley do not offer help with adapting your theme or plugin within regular support.
