How to find what actions/filters/hooks are triggered on creating a New Question or Answer?

Hi Rahul,

As you know, sometimes to post new questions on my site, I use customized function, which creates CPT – Questions and Answers (code snippet posted below). They both are created and posted fine with my function. But they are missing the relevant meta activities. So my questions are –

1. What are different meta activities used by AnsPress while creating/updating a question/answer, specially how to use “__ap_activity” with my function?
2. How to find all the functions/meta activities (by different plugins) in general (not localized to anspress only), which are triggered on creating a new question/answer? [I am particularly interested in finding what is triggered in “Next Scripts: Social Networks Auto Poster”, because, I found that this plugin does work with AnsPress, but only when I create the new question from AnsPress itself, it does NOT trigger when I create the new question from my customized function. I want it to trigger from my function, but I couldn’t figure out how to do that?]
3. OR, is there any way, by which wordpress can automatically process, all the functions etc. after creating the new post with `

   wp_insert_post

   ` just like it does automatically when new post is created from admin section?

Relevant part of my function –

<?php
function AddQuestionToAnsPress($question_title, $question_content, $answer_content, $subject_id, $exam_id) {
    $path = $_SERVER['DOCUMENT_ROOT'];
    $path .= "/wp-blog-header.php";
    require($path);

    $question_title = strip_tags($question_title);
    $category_id = $subject_id;
    $category = array($category_id);

    $tag_subject_id = $subject_id;
	$tags = array(25, $tag_subject_id);

    wp_set_current_user(26);
    $user_id_for_question = 26;

    $question_array = array(
        'post_title' => $question_title,
        'post_author' => $user_id_for_question,
        'post_content' => $question_content,
        'post_type' => 'question',
        'post_status' => 'publish',
        'comment_status' => 'open'
    );

    $question_post_id = wp_insert_post($question_array);
    $question_permalink = get_permalink($question_post_id);

    wp_set_post_terms($question_post_id, $category, 'question_category');
    wp_set_post_terms($question_post_id, $tags, 'question_tag');
    update_post_meta($question_post_id, '_at_exam_id', $exam_id);

    if ($question_post_id && $answer_content != "") {
        wp_set_current_user(26);
        $user_id_for_answer = 26;


        $ans_array = array(
            'post_author' => $user_id_for_answer,
            'post_content' => $answer_content,
            'post_type' => 'answer',
            'post_status' => 'publish',
            'post_parent' => $question_post_id,
            'comment_status' => 'open',
        );
        $answer_post_id = wp_insert_post($ans_array);
    }
    
	if ($answer_post_id) {
        update_post_meta($question_post_id, '_ap_selected', $answer_post_id);
        update_post_meta($answer_post_id, '_ap_best_answer', 1);
    }
	
    $anspress_link = $question_permalink;
    return array('anspress_link' => $anspress_link, 'question_post_id' => $question_post_id, 'answer_post_id' => $answer_post_id);
}
?>

Thanks.
