Step-by-Step Fixes for WooCommerce Amazon Pay Not Working

Now that we know the common problems, let’s fix them one by one. Each solution below is simple, clear, and easy to follow. Regardless of your level of IT expertise, following these steps will help you get Amazon Pay back up and running.

Step 1: Check Plugin Compatibility and Versions

The first thing to check is your plugin versions.

Outdated plugins often cause issues.

Here’s what to do:

  • Go to your WordPress dashboard.
  • Navigate to Plugins > Installed Plugins.
  • Verify that WooCommerce is up to date with the most recent version.
  • Also check that the Amazon Pay plugin is up to date.

If you’re using an old version, update both plugins. Always take a backup before updating. Some features may break if updates are skipped for too long.

Also, ensure your WordPress version is compatible with the plugins. Outdated PHP versions can also result in problems. PHP 7.4 or higher is recommended.

Step 2: Verify Amazon Seller and MWS Credentials

Amazon Pay needs the correct credentials to work.

If those are wrong, nothing will function correctly.

Here’s how to check:

  • Log in to your Amazon Seller Central account.
  • Go to Integration > MWS Access Keys.
  • Copy your Seller ID, Access Key ID, and Secret Key.
  • In your WordPress dashboard, go to WooCommerce > Settings > Payments > Amazon Pay.
  • Paste the credentials carefully. Avoid extra spaces.

Make sure you’re using Live Mode and not Sandbox, unless you’re testing. Also, ensure your Amazon Pay account is approved for production use.

This step fixes many cases of WooCommerce Amazon Pay login failed and api connection errors.

Step 3: Fix WooCommerce Amazon Pay 403 Error

Something is blocked if you’re receiving a 403 error.

This is often related to server permissions or incorrect API access.

Try the following:

  • Verify that none of your API keys have been revoked or expired.
  • Make sure your IAM user in Amazon has the right permissions.
  • Contact your hosting provider to check if IP access is being blocked.
  • Disable any firewall or security plugin temporarily and test again.

403 errors are often linked to Amazon Pay WooCommerce errors caused by API denial or access rules.

Step 4: Resolve Login and Checkout Failures

If users can’t log in with Amazon Pay, the issue is likely session-based.

Here’s how to troubleshoot it:

  • Empty the cache and cookies in your browser.
  • Try using incognito mode or a private window to log in.
  • Ensure your store uses HTTPS (SSL). Amazon blocks HTTP logins.
  • Check if the problem happens only for certain browsers or devices.
  • Disable other login-related plugins and test again.

These steps help resolve WooCommerce Amazon Pay login failed issues that break the user login or cause timeout errors.

Step 5: Review WooCommerce & Server Logs

Error logs tell you what’s happening behind the scenes.

To check WooCommerce logs:

  • Go to WooCommerce > Status > Logs.
  • In the dropdown, select Amazon Pay logs (if available).
  • Look for keywords like 403, authentication failed, or API error.

To check server logs:

  • Access your hosting control panel.
  • Navigate to the error logs section.
  • Look for blocked IPs, failed requests, or timeouts.

Look for repeated patterns or exact error codes.

This step is important to fix Amazon Pay api errors WooCommerce problems which don’t show on the screen.

  • Clone your website to a test environment.
  • Apply changes and updates there first.
  • Once everything works, apply them to your live site.

Advanced Fixes & Developer Tips

If basic fixes haven’t solved your Amazon Pay issue, don’t worry. Some problems need deeper investigation. These advanced steps can help if you’re still facing errors. These are best suited for developers or users comfortable with debugging tools.

Conflict Testing with Other Plugins

Sometimes, other plugins interfere with Amazon Pay.

  • Install the free Health Check & Troubleshooting plugin.
  • Go to Tools > Site Health > Troubleshooting Mode.
  • Enable troubleshooting mode for your admin session.
  • Turn off every plugin but Amazon Pay and WooCommerce.
  • Check to see if the issue has been fixed.

If Amazon Pay starts working, another plugin is causing the issue.

To find the culprit:

  • Reactivate each plugin individually.
  • Check Amazon Pay after each reactivation.
  • Stop when the issue returns.

This method helps isolate the plugin conflict safely.

Theme Conflicts

Themes can also block the Amazon Pay button from showing.

  • Use a default theme for WordPress, such as Storefront.
  • Go to Appearance > Themes, activate Storefront.
  • Check your checkout page for Amazon Pay.

Your theme is the problem if the button shows up.

You may need a developer to fix your theme’s compatibility.

  • Missing wp_footer() or wp_head() in theme files.
  • Custom checkout templates missing Amazon hooks.

Always test on a staging site before making live changes.

Fixing JavaScript or AJAX Errors

Many checkout issues come from JavaScript problems.

To identify these errors:

  • Right-click on the checkout page.
  • Select the Console tab after clicking Inspect.
  • Look for red error messages.

Common JavaScript issues include:

  • Conflicts between Amazon Pay and other scripts.
  • Missing files or failed AJAX calls.
  • Mixed content (loading HTTP on HTTPS sites).

Steps to resolve:

  • Make sure your site loads everything over HTTPS.
  • Disable any minification or script merging plugin temporarily.
  • Try excluding Amazon Pay scripts from optimization.

Tools like Query Monitor can also help trace failed AJAX requests.

These advanced steps go beyond simple fixes. They help solve deeper problems like hidden errors and code conflicts. It is ok to seek assistance if you are unsure about how to complete these responsibilities. A developer or WooCommerce expert can assist you.

Prevention Tips – Keep Amazon Pay Working Smoothly

Fixing Amazon Pay issues can be frustrating, but most are avoidable. Once your store is working again, it’s important to keep it stable. A few simple steps can help prevent future errors and reduce downtime.

Keep Plugins and WooCommerce Updated

Outdated plugins are a major cause of payment issues.

To avoid this:

  • Update WooCommerce regularly.
  • Keep the Amazon Pay plugin current.
  • Also update WordPress core when new versions release.

Make a backup of your website before making any changes. In the event that something breaks, this safeguards your data.

Use a Quality Hosting Provider

Some issues come from poor server setups or limitations.

Choose a host that supports:

  • WooCommerce optimization
  • PHP version 7.4 or higher
  • SSL (HTTPS enabled by default)

Ask your hosting provider to enable logging features and secure permissions.

Enable Error Logging

Logs help detect problems before they become critical.

  • Turn on debug logging
  • Review logs weekly for unusual activity

Test Regularly in a Staging Environment

Don’t wait for a live issue to appear.

  • BlogVault
  • Your host’s built-in cloning feature

First, test the modifications on the staging site. Move them to live only after making sure everything functions.
