Remove rewrite endpoint on deactivation?

Question

I'm using Milo's answer to add a Rewrite Endpoint as part of my plugin.

Is there a straight-forward way to remove a Rewrite Rule upon deactivation?

I found this snippet but I'd expect a "remove_rewrite_endpoint" to match add_rewrite_endpoint

Also, how do I know what to look for in the rewrite rules list when add_rewrite_endpoint was used to add the rule?

Answer 1

All you need is flush the rewrite rules on deactivation. For example, in the main plugin file:

register_deactivation_hook( __FILE__, function() {
    flush_rewrite_rules();
});
