This is a very simple plugin that creates a new adminbar menu with a list of pertinent API calls used on a page.
However, no good thing happens in a vacuum, and you good folks, are developers.
In order to log API calls, you should invoke the <code>log_api_call()</code> method of the <code>$ab_api_logger</code> global object. Of course, if you prefer, you can instantiate your own object using the <code>AB_API_Logger</code> class.
The <code>log_api_call()</code> method takes two properties. The first is an array of URLs that will be included as menu items (easy access, easy click to see responses). By default, the plugin maintains a property <code>$api_calls</code> with this array and uses it to parse out the menu items.
However, if you wish to maintain your own array, you can do that too. The plugin takes care of what it needs, and you can feel free to maintain what you need.
The second argument for the <code>log_api_calls()</code> method is the URL that will be added to the adminbar menu. You can escape it if you want, but I will as well for security.
The reason I built this plugin is because I deal with APIs a lot. My normal approach to API integration is to use a pre-existing PHP library or, more commonly, build a library around the API so I can use it easily without having to remember everything.
Usually, this means I create a class and that class is filled with methods that construct a URL based on parameters and then use <code>wp_remote_get()</code> to retrieve the response from the API. Anytime after the URL is created, invoke this plugin:
<pre><code>if( class_exists( 'AB_API_Logger' ) ) { // Example API Call: $api_url (http://api.example.com?apikey=asdfASD234&post_id=213) global $ab_api_logger; $ab_api_logger->log_api_call( $ab_api_logger->api_calls, $api_url ); } </code></pre>

This is a tool to understand your rewrite rules (“Pretty Permalinks”). It is indispensable if you are adding or modifying rules and want to understand how they work (or why they don’t work).
It is only an analyzer, it does not change any rules for you. It parses the rules down to their components and shows the connection with the resulting query variables. It allows you to try out different URLs to see which rules will match and what the value of the different query variables will be (see screenshots).
This plugin was written as a tool to help answering questions about rewrite rules on <a href="http://wordpress.stackexchange.com/" rel="nofollow ugc">the WordPress Stack Exchange</a>.

Monkeyman Rewrite Analyzer

Throws a warning if WP_DEBUG is on, other than that still a very handy tool to check your rewrite rules.

Very useful

Helped me sort some issues with the rewrite rules when developing a plugin. Works fine with WordPress 5.2 and does what you need it too.
