For posterity’s sake. These are the functions I created and used:
This function searches the corresponding Woo Commerce Product ID which is attached to the event-postID (connected to the event-area, which is connectet to the woocommerce product).

function getProductID($eventID){
	global $wpdb;
	$result1 = $wpdb->get_results('SELECT meta_value FROM wp_2_postmeta WHERE meta_key = "_event_area_id" AND post_ID = '.$eventID);
	$eventereaID = $result1[0]->meta_value;

	$result2 = $wpdb->get_results('SELECT meta_value FROM wp_2_postmeta WHERE meta_key = "_pricing_options" AND post_ID = '.$eventereaID);
	$productID = $result2[0]->meta_value;

	if($productID>0){
		return $productID;
	}
	return false;
}

And this function adds an event programmatically

function add_ticket_to_cart($eventid, $ticket_type_id, $count ){
	global $woocommerce;
	$data = array(
		'event_id' => $eventid,
	);

	if ( is_object( $woocommerce->cart ) ) {
		// Generate a ID based on product ID, variation ID, variation data, and other cart item data
		$cart_id = $woocommerce->cart->generate_cart_id( $ticket_type_id, '', '', $data );

		// See if this product and its options is already in the cart
		$cart_item_key = $woocommerce->cart->find_product_in_cart( $cart_id );
		if ($count == 0) {
			if ($cart_item_key) {
				$woocommerce->cart->set_quantity( $cart_item_key, 0 );
			}
		} else {
			if ($cart_item_key) {
				$woocommerce->cart->set_quantity( $cart_item_key, $count );
			} else {
				$woocommerce->cart->add_to_cart( $ticket_type_id, $count, '', '', $data );
			}
		}
	}
	return $cart_id;
}

Thanks for the help. This was exactly the lead I needed to accomplish this.

What I did, I created a new function based on reserve_current_user.

I searched with my own wp sql query which event+productid combination I want to add to the cart. The function is placed an ajax/php file, which I can call from jquery/javascript.

What I’ve found so far in
assets/js/features/event-area/ui.js

Is the EATicketSelection which can be used to print out the while ticket-selectform, it automatically uses the event/post ID for construction and it creates all event-listeners for adding/updating and removing events on the form.

What I really would like to know is which kind of ajax call can be used to push an event to the cart with JS/PHP or ajax when I have an event-id.
