How to Fix 429 Error with IndexNow API

Hello,

We apologize for the issue you are facing with the 429 error in the IndexNow API. Since you’ve already tried disabling auto-submission and changing the API key, here are a few additional steps you can take:

1. Wait for a While: After making changes, it’s important to wait for a few hours before attempting to submit URLs again. This allows the system to reset.

2. Check for Other Sites on Shared Hosting: If you are on shared hosting, other websites on the same server may be using up the quota assigned to your shared IP address. In this case, you may need to wait it out or contact your hosting provider for assistance.

3. Clear Your Website Cache: Make sure to clear your website cache after making changes to ensure that everything is updated properly. You can follow this guide on how to clear cache in WordPress.

If the issue persists after trying these steps, please reply to this ticket with your site URL so that a human agent from our support team can assist you further. Thank you for raising this concern!

Hello,

When you see a 429 error, it means that the IP address of your website is sending too many requests to the API.

Also, that error suggests that you are exhausting the quota limit for the number of publishing requests per day.

However, if you have other websites on the same server or are on shared hosting, there’s a possibility that other websites may be using up the quota.

We suggest you install the following plugin from Bing on your website and try submitting some URLs to understand if the issue is only from the IndexNow API implementation: https://wordpress.org/plugins/indexnow/

Let us know how it goes. Looking forward to helping you.

Thank you.
