Frequently asked questions

What does SEO Fields API Support require?

The published plugin requires WordPress 6.2 or later and an active Yoast SEO installation. The WordPress.org listing reports version 1.1, tested up to WordPress 6.7.7, as checked on September 8, 2026. Check the current listing and test your configuration before deployment; compatibility with every newer release or multilingual plugin is not established by those requirements.

How do I install the plugin?

1. Download the plugin from the WordPress.org listing.
2. Upload the ZIP through the WordPress Plugins screen, then activate it.
3. Confirm that Yoast SEO is active.
4. Test an update on a staging post before using a bulk workflow.

How do I update a post's SEO fields?

Send an authenticated PUT request to https://example.com/wp-json/wp/v2/posts/123, replacing the domain and post ID. A request body can contain:

{
  "meta": {
    "_yoast_wpseo_title":
      "Page title",
    "_yoast_wpseo_metadesc":
      "Description of the page"
  }
}

Pages use the /wp-json/wp/v2/pages/123 route. Check the actual REST route for custom post types. Read the response and verify the saved fields before continuing a batch.

How should API requests authenticate?

For an external script, WordPress supports Application Passwords over HTTPS. Requests made inside a logged-in WordPress session use cookie authentication and a REST nonce; a nonce alone does not authenticate an external script. The account must have permission to edit the target content. JWT requires a separate authentication implementation. See the WordPress REST authentication documentation.

Where can I review or report a problem?

Review the source code and plugin listing for the implementation and current release details. Include the WordPress version, Yoast SEO version, request route and error response when requesting help. Remove credentials from any example you share.
