Example where we enforce a maximum balance of 1000 points in myCRED. If a user is about to get points that exceeds this limit, we decline the transaction. Goes into your custom plugin or child theme's functions.php file.

enforce-max-mycred-balance

/**
 * Enforce Maximum
 * Make sure users can not earn more than 1000 points.
 * @version 1.0
 */
function mycred_enforce_max_balance( $run, $request, $mycred ) {

	extract( $request );

	// The maximum balance a user can have
	$maximum = 1000;

	// Get the users balance
	$balance = $mycred->get_users_balance( $user_id );

	// Check if we already reached our max
	if ( $balance >= $maximum ) return false;

	// Next make sure this transaction will not bring us over the limit
	$balance += $amount;
	if ( $balance > $maximum ) return false;

	// Below limit, please continue
	return $run;

}
add_filter( 'mycred_add', 'mycred_enforce_max_balance', 1, 3 );

@gabrielmerovingi i need help.
How can i restrict how many points a post or page can give out.
example: i create a post or page i want that post or page to award x number of points only or award x numbers or users on points for that particular post or page. once the target is meet, subsequent visit will will received a not receive points again for that post.

or

using the click on links.
a link can only award specific number of points using shortcode.
e.g i create a link, that link should give out only 500 points, once that link has given out 500 points, it shouldn't give out points again for subsequent clicks.
