// Modify REST API response to include only necessary post data
function custom_modify_rest_post_data($data, $post, $request) {
// Initialize an empty array to store modified data
$modified_data = array();

// Add necessary post data to the modified array
$modified_data['id'] = $data->data['id'];
$modified_data['title'] = $data->data['title']['rendered'];
$modified_data['content'] = $data->data['content']['rendered'];
$modified_data['excerpt'] = $data->data['excerpt']['rendered'];
$modified_data['date'] = $data->data['date'];
$modified_data['author'] = $data->data['author'];
$modified_data['slug'] = $data->data['slug'];

// Add featured image URL if available
if (isset($data->data['featured_media']) && $data->data['featured_media'] !== 0) {
$featured_image_id = $data->data['featured_media'];
$featured_image_url = wp_get_attachment_image_src($featured_image_id, 'full');
