Automatically import content to wordpress from a json file

You can use wp_insert_post() to add a new post programmatically. For Example,

$my_post = array(
  'post_title'    => wp_strip_all_tags( $json->title ),
  'post_content'  => $json->body,
  'post_status'   => 'publish',
  'post_author'   => 1,
  'post_category' => $json->categories
);
 
// Insert the post into the database
wp_insert_post( $my_post );

Your link has expired so I could not see the structure of JSON data. But the answer would be the same. Set up a cron job or use their webhook (if they have any) to call a page where you have set up this wp_insert_post()for automatic posting.

write a custom simple script that retrieves the json data and creates wp posts using the wp REST API and replace the $json_url variable with the URL of your JSON endpoint

we added a post_exists() function to check if a post with the same title already exists in the wp database

// URL of the JSON endpoint
$json_url = 'https://api.webscraper.io/api/v1/scraping-job/4851593/json?api_token=aLXQWr2IbQCefgiLc1PfIjfx7GqvsBd3APVbU1pHchszzzFIFa6HFKsNmpft';

// Retrieve JSON data
$response = file_get_contents($json_url);

// Check if data was successfully retrieved
if ($response === false) {
    die('Failed to fetch JSON data.');
}

// Convert JSON data to associative array
$data = json_decode($response, true);

// Check if JSON decoding was successful
if ($data === null) {
    die('Failed to decode JSON data.');
}

// Function to check if post already exists
function post_exists($title) {
    global $wpdb;
    $query = $wpdb->prepare("SELECT ID FROM $wpdb->posts WHERE post_title = %s AND post_type = 'post'", $title);
    $post_id = $wpdb->get_var($query);
    return $post_id;
}

// Loop through each item in the JSON data
foreach ($data as $item) {
    // Check if post already exists
    if (post_exists($item['title'])) {
        echo 'Post with title "' . $item['title'] . '" already exists. Skipping...<br>';
        continue;
    }

    // Create new post
    $post_data = array(
        'post_title' => $item['title'], // Assuming 'title' field exists in your JSON data
        'post_content' => $item['content'], // Assuming 'content' field exists in your JSON data
        'post_status' => 'publish', // Publish the post immediately
        // You can include other fields like 'post_excerpt', 'post_category', 'tags_input', etc. as needed
    );

    // Insert the post into WordPress
    $post_id = wp_insert_post($post_data);

    // Check if post was inserted successfully
    if (is_wp_error($post_id)) {
        echo 'Failed to insert post: ' . $post_id->get_error_message();
    } else {
        echo 'Post inserted successfully with ID: ' . $post_id . '<br>';
    }
}
