Check if post is added manually or through wp_insert_post()

Question

I might not be thinking this right but here is my situation:

• I have a custom post type called events.
• Some of my events are imported from an API and inserted through wp_insert_post() (in a plugin), some are added manually in the admin edit screen.
• On post saving I need to add some informations to the post_meta but only if the post is added manually (through the admin edit screen).

So I am hooking into save_post_events and performing some security checks but I have no idea how to check if the request is only coming from the admin edit page because right now the save_post action triggers also if the post is added with the wp_insert_post function.

Any ideas?

Thanks

I have found a solution without adding any other metaboxes. I haven't thought about it but the import function in my plugin uses a nonce so I just check if my nonce is set or not.

Here is my save_post_events function:

add_action( 'save_post_events', 'wse_327066_example', 10, 3);
function wse_327066_example( $post_id, $post, $update ) {
  if ( defined( 'DOING_AUTOSAVE' ) && DOING_AUTOSAVE || $post->post_status == 'trash' || !current_user_can( 'edit_posts' ) || isset( $_POST['_import_nonce'] ) ) 
    return;

  # Now I can do whatever I want with posts saved from the admin edit screen... 
}
