Ensure WooCommerce is installed and activated on your WordPress site. The API is part of the WooCommerce core, so no additional downloads are required.
Step 2: Access WooCommerce Hooks
The Fees API is accessible via hooks such as:
– `woocommerce_cart_calculate_fees`: Used to calculate and add fees during checkout.
Step 3: Add Custom Fees Programmatically
Add custom PHP code to your theme’s `functions.php` file or a custom plugin to interact with the API. Below is an example of adding a custom fee:
“`php
add_action(‘woocommerce_cart_calculate_fees’, ‘custom_fee_example’);
function custom_fee_example() {
global $woocommerce;
// Define the fee
$fee = 5.00; // Fixed fee of $5
// Add the fee to the cart
$woocommerce->cart->add_fee(__(‘Custom Handling Fee’, ‘text-domain’), $fee);
}
“`
Step 4: Test Your Implementation
After adding the custom code, perform a test checkout to verify that the fee appears as expected.
4. Implementing WooCommerce Fees API in Your Store
The implementation process involves understanding key aspects of the API and applying them effectively.
Adding Conditional Fees
For instance, you may want to add a fee only if the cart total is below $50. Here’s how you can achieve this:
“`php
add_action(‘woocommerce_cart_calculate_fees’, ‘conditional_fee_example’);
function conditional_fee_example() {
global $woocommerce;
// Check if cart total is below $50
if ($woocommerce->cart->total < 50) {
$fee = 10.00; // Add a $10 fee
$woocommerce->cart->add_fee(__(‘Low Order Fee’, ‘text-domain’), $fee);
}
}
“`
Removing or Modifying Fees
To remove or modify fees, you can use filters and additional logic within the same hook.

FAQs
Q1: Can I apply different fees for specific products?
Yes, you can add conditional logic to target specific products. For example, check the product IDs in the cart and apply a fee only for those products.
“`php
add_action(‘woocommerce_cart_calculate_fees’, ‘product_specific_fee’);
function product_specific_fee() {
foreach (WC()->cart->get_cart() as $cart_item) {
if ($cart_item[‘product_id’] == 123) { // Replace 123 with your product ID
$fee = 5.00; // Fee for specific product
WC()->cart->add_fee(__(‘Product-Specific Fee’, ‘text-domain’), $fee);
}
}
}
“`
Q2: How can I remove a fee programmatically?
You can modify or remove fees by accessing the fees array within the cart object. Use the `woocommerce_cart_calculate_fees` hook to clear specific fees.
“`php
add_action(‘woocommerce_cart_calculate_fees’, ‘remove_fee_example’);
function remove_fee_example() {
foreach (WC()->cart->get_fees() as $key => $fee) {
if ($fee->name === ‘Custom Handling Fee’) {
unset(WC()->cart->fees[$key]);
}
}
}
“`
Q3: Does the Fees API work with multi-currency plugins?
Yes, it works, but you must ensure the fee amounts are dynamically adjusted based on the currency. Use currency conversion logic or compatibility functions provided by your multi-currency plugin.
Q4: Can I display a breakdown of fees on the checkout page?
By default, fees are displayed as a single line item, but you can customize the display using WooCommerce templates. Override the `cart-totals.php` file in your theme to show detailed fee breakdowns.
Q5: Can I set a maximum limit for the fees?
Yes, you can use conditional logic to cap the fee amount. For instance, you can ensure the fee does not exceed $20:
“`php
add_action(‘woocommerce_cart_calculate_fees’, ‘max_fee_limit’);
function max_fee_limit() {
$fee = 10.00; // Base fee
$max_limit = 20.00; // Maximum fee limit
$applied_fee = min($fee, $max_limit);
WC()->cart->add_fee(__(‘Capped Fee’, ‘text-domain’), $applied_fee);
}
“`
Q6: Are WooCommerce fees taxable?
Yes, you can set fees to be taxable by specifying the tax class when adding the fee. For example:
“`php
WC()->cart->add_fee(__(‘Taxable Fee’, ‘text-domain’), 10.00, true, ‘standard’);
“`
The third parameter (`true`) enables taxation, and `’standard’` specifies the tax class.
Q7: How can I debug issues with the WooCommerce Fees API?
Use WordPress debugging tools or WooCommerce logs to identify errors. Add the following code to enable debug logs in WooCommerce:
1. Go to WooCommerce > Settings > Advanced > Logs and enable logging.
2. Use `error_log()` in your custom functions to output debug information:
“`php
error_log(‘Fee calculation executed’);
“`
Q8: Can I use Fees API to provide discounts instead of adding fees?
Yes, you can use negative values to represent discounts. For example:
“`php
WC()->cart->add_fee(__(‘Discount’, ‘text-domain’), -5.00);
“`
This will reduce the cart total by $5.
Q9: Is it possible to add fees based on shipping methods?
Yes, you can check the selected shipping method and apply fees accordingly. Use this snippet:
“`php
add_action(‘woocommerce_cart_calculate_fees’, ‘shipping_method_fee’);
function shipping_method_fee() {
$chosen_method = WC()->session->get(‘chosen_shipping_methods’)[0];
if ($chosen_method === ‘flat_rate:1’) { // Replace with your shipping method ID
WC()->cart->add_fee(__(‘Shipping Method Fee’, ‘text-domain’), 2.00);
}
}
“`
Q10: How do I make fees optional for customers?
Use WooCommerce checkout fields to let customers opt-in for a fee. Create a custom checkbox and add the fee conditionally based on its value.
“`php
add_action(‘woocommerce_cart_calculate_fees’, ‘optional_fee’);
function optional_fee() {
if (isset($_POST[‘optional_fee_checkbox’]) && $_POST[‘optional_fee_checkbox’] === ‘yes’) {
WC()->cart->add_fee(__(‘Optional Service Fee’, ‘text-domain’), 5.00);
}
}
