**1. Introduction**
The integration of Google Pay with WooCommerce through Stripe enables customers to make fast and convenient payments. However, problems may arise that prevent the Google Pay quick payment button from working properly in your WooCommerce store. This guide will walk you through the steps to diagnose and resolve the issue.
**2. Understanding the Problem**
Symptoms of the problem may include:
* The page turns gray and loads indefinitely after clicking the Google Pay button on mobile devices.
* On desktop computers, an error message appears in the browser console:
“`javascript
Uncaught (in promise) IntegrationError: Unexpected call to paymentFailed(). Ensure you are either submitting a payment or calling paymentFailed() once per expressCheckout Element confirm event.
“`
* In WooCommerce, an error message appears: “First name and last name for billing is required.”
* The problem occurs regardless of the payment method chosen (Google Pay, credit card, etc.).
**3. Possible Causes of Error**
The cause of the problem may be:
* Outdated plugin or WordPress versions.
* Incorrect configuration of the Stripe plugin.
* Conflicts with other plugins.
* JavaScript errors on the page.
* Missing required fields in the order form.
**4. Step 1: Check System Requirements**
Ensure that your store meets the minimum system requirements for the Stripe and Google Pay plugins.
Requirements:
* WordPress version 5.0 or higher.
* WooCommerce version 3.0 or higher.
* Latest version of the Stripe plugin installed.
* SSL certificate installed on the site (https).
If any of these requirements are not met, update the relevant elements.
**5. Step 2: Update Plugins and WordPress**
Outdated software can cause errors and incompatibilities.
How to do it:
1. Log in to your WordPress panel.
2. Go to **Dashboard > Updates**.
3. If an update is available for WordPress, apply it.
4. Go to **Plugins > Installed Plugins**.
5. Update the WooCommerce and Stripe plugins to the latest versions.
6. Test if the problem has been resolved.
**6. Step 3: Verify Stripe Configuration**
Ensure that the Stripe plugin is properly configured.
How to do it:
1. Go to **WooCommerce > Settings > Payments**.
2. Click on **Stripe** to access its settings.
3. Check if the API keys (Publishable and Secret) are correctly entered.
4. Ensure that the **Enable Payment Request Buttons** option is enabled.
5. Verify the Google Pay settings and ensure they are properly configured.
**7. Step 4: Check for Plugin Conflicts**
Other plugins may cause conflicts with the Stripe and Google Pay plugins.
How to do it:
1. Disable all plugins except WooCommerce and Stripe.
2. Test if the problem still occurs.
3. If the problem is resolved, activate plugins one by one, testing functionality each time.
4. Identify the plugin causing the conflict and consider replacing or contacting its developer.
**8. Step 5: Diagnose JavaScript Errors**
JavaScript errors may prevent the Google Pay quick payment button from working properly.
How to do it:
1. Open your page in Chrome.
2. Press **F12** to open the developer tools.
3. Go to the **Console** tab.
4. Try using the Google Pay button and observe if new error messages appear.
5. Note any error messages and try to interpret them.
If errors occur, they may indicate specific problems with code or configuration.
**9. Step 6: Verify Payment Fields**
The error message “First name and last name for billing is required” suggests that necessary information is missing from the order form.
How to do it:
1. Go to **WooCommerce > Settings > Accounts and Privacy**.
2. Ensure that the **Allow customers to place orders without an account** option is enabled, if you don’t require login.
3. Go to **WooCommerce > Settings > Advanced > Shop Pages**.
4. Verify that the **Order** page is properly assigned.
5. If you use plugins modifying order fields, ensure the **First name** field is not removed or hidden.
**10. Step 7: Contact Stripe Technical Support**
If the problem persists, consider contacting Stripe technical support directly.
How to do it:
1. Visit the [Stripe Support](https://support.stripe.com/) page.
2. Choose contact via email or chat.
3. Describe the problem in detail, including:
* Versions of WordPress, WooCommerce, and Stripe plugins.
* Error messages from the browser console.
* Steps taken to resolve the issue.
**11. Summary**
