How to send WordPress article data to an external API during publishing

There are a few plugins that can help you to do this, such as:

• WP Webhooks
• AutomatorWP

Once you have installed and activated one of these plugins, you can use it to create a custom logic that is hooked to the publish_post action.

You could also use something like Zapier, to create a "Zap" that triggers a POST request to an external API when a new article is published

If you don’t want to use a plugin, you can also add your own custom code to intercept the publishing event and send the article data to the external API.

Example:

function send_article_data_to_external_api($post_id) {
  // Get the article data.
  $article_data = array(
    'title' => get_the_title($post_id),
    'content' => get_the_content($post_id),
    'images' => get_attached_media('image', $post_id),
  );

  // Make a POST request to the external API.
  // ...
}

// Hook the function to the `publish_post` action.
add_action('publish_post', 'send_article_data_to_external_api');
