WooCommerce Notice Messages, how do I edit them?

Question

I\'m trying to figure out where WooCommerce creates it\'s messages for when there is a success, error or notice in WooCommerce. I want to edit those messages to fit the scenario

Answer 1

I came across this answer and was able to implement for a production site. This answer is related to woocommerce error codes notices. You need to find the codes in the separate class files (~woocommerce/includes/). For my purpose the code was in ~woocommerce/includes/class-wc-coupon.php

/**
 * Modify the coupon errors:
*/

 add_filter( 'woocommerce_coupon_error', 'wpq_coupon_error', 10, 2 );

 function wpq_coupon_error( $err, $err_code ) {
  return ( '103' == $err_code ) ? '' : $err;
 }
