need help in API for rankmath

Hello,

We apologize for the issue you are facing with the Rank Math API. It seems like you are able to access your URLs directly, but the API is not returning the expected data.

Here are a few steps you can take to troubleshoot the issue:

1. Enable Headless CMS Support: Ensure that you have enabled the Headless CMS support in Rank Math. You can do this by navigating to Rank Math SEO → Dashboard → Others and enabling the Headless CMS support option.

2. Check Firewall Settings: If your website uses a security plugin or firewall, it might be blocking access to the Rank Math API endpoint. Make sure to whitelist the following endpoint in your firewall:

   https://your-domain.com/wp-json/rankmath/v1/getHead?url=https://your-domain.com/hello-world

3. Check for Errors: If you are still encountering issues, please check if there are any error messages being returned by the API. Common errors include:

   • No Route Was Found Matching the URL and Request Method: This indicates that Headless CMS support is not enabled.
   • Invalid Parameter(s) URL: This occurs if the URL parameter is incomplete or empty.
   • Missing Parameter(s) URL: This happens when the URL parameter is not included in your request.

4. API Timeout: Ensure that your website is not taking too long to respond (more than 30 seconds), as this could lead to a timeout error.

If you continue to experience problems, please reply to this ticket with any error messages you are receiving, and a human agent from our support team will assist you further. Thank you for raising this concern!
