<p>This is a very simple plugin that creates a new adminbar menu with a list of pertinent API calls used on a page.</p>
<p>However, no good thing happens in a vacuum, and you good folks, are developers.</p>
<p>In order to log API calls, you should invoke the <code>log_api_call()</code> method of the <code>$ab_api_logger</code> global object. Of course, if you prefer, you can instantiate your own object using the <code>AB_API_Logger</code> class.</p>
<p>The <code>log_api_call()</code> method takes two properties. The first is an array of URLs that will be included as menu items (easy access, easy click to see responses). By default, the plugin maintains a property <code>$api_calls</code> with this array and uses it to  parse out the menu items.</p>
<p>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.</p>
<p>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.</p>
<p>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.</p>
<p>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 <strong>after</strong> the URL is created, invoke this plugin:</p>
<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>

API Request Collector

This plugin is made for plugin developers that work with APIs and need easy access to debug information.

Automattic

Thorsten Ott

<p>This plugins adds more features to the debug-bar and is mainly aimed at developers who like to debug their code or want to measure runtimes to find glitches in their code.<br />
It also allows lookup of variables by adding simple code snippets in your source.</p>
<p>Please note that this plugin should be used solely for debugging or on a development environment and is not intended for use in a production site.</p>
<h3>Requirements</h3>
<p>This plugin requires <a href="https://wordpress.org/extend/plugins/debug-bar" rel="ugc">the debug-bar plugin >0.5</a> and a developers’ brain to work correctly.</p>
<h3>Usage</h3>
<h4>Usage example to debug the loop of a theme</h4>
<p>Add your checkpoints in the index.php or any other template file as shown below.</p>
<pre><code><?php if (have_posts()) : ?>

<?php Debug_Bar_Extender::instance()->checkpoint('loop start'); ?>

<?php while (have_posts()) : the_post(); ?>

<?php Debug_Bar_Extender::instance()->trace_var( $post ); ?>

<?php Debug_Bar_Extender::instance()->checkpoint('loop1'); ?>

<div <?php post_class() ?> id="post-<?php the_ID(); ?>">
<?php //before_post(); ?>
<h2><a href="<?php the_permalink() ?>" rel="bookmark" title="<?php printf(__('Permanent Link to %s', 'kubrick'), the_title_attribute('echo=0')); ?>"><?php the_title(); ?></a></h2>
<small><?php the_time(get_option('date_format')) ?> by <?php the_author() ?></small>
<div class="entry">
<?php the_content(__('Read the rest of this entry &raquo;', 'kubrick')); ?>
</div>
<p class="postmetadata"><?php the_tags(__('Tags:', 'kubrick') . ' ', ', ', '<br />'); ?> <?php printf(__('Posted in %s', 'kubrick'), get_the_category_list(', ')); ?> | <?php edit_post_link(__('Edit', 'kubrick'), '', ' | '); ?> <?php comments_popup_link(__('No Comments »', 'kubrick'), __('1 Comment »', 'kubrick'), __('% Comments »', 'kubrick')); ?></p>
<?php after_post(); ?>
</div>

<?php Debug_Bar_Extender::instance()->checkpoint('loop2'); ?>

<?php endwhile; ?>

<?php Debug_Bar_Extender::instance()->checkpoint('loop end'); ?>

<div class="navigation">
<div class="alignleft"><?php next_posts_link(__('&laquo; Older Entries', 'kubrick')) ?></div>
<div class="alignright"><?php previous_posts_link(__('Newer Entries &raquo;', 'kubrick')) ?></div>
</div>
<?php else : ?>
</code></pre>
<h3>Advanced usage</h3>
<p>Looking at the source of the debug-bar-extender.php you will notice that there are various filters to control the default settings. This is useful when you are working on a multisite install and want to use the debug bar without having to adjust the settings every time. Here’s an example of how settings enforced by a php file in mu-plugins/ could look like</p>
<pre><code>add_filter( 'debugbarextender_default_settings', 'my_debug_bar_extender_settings' );
// enforce debug bar settings
function my_debug_bar_extender_settings( $default_settings ) {
    $default_settings = array(
            'enable_profiler'               => 1,
            'enable_variable_lookup'        => 1,
            'track_default_vars'            => 0,
            'add_default_checkpoints'       => 1,
            'savequeries_debugmode_enable'  => 1,
            'use_error_log'                 => 0,
            'allow_url_settings'            => 1,
            'enable_admin_bar_menu'         => 1,
    );
    return $default_settings;
}

add_filter( 'debugbarextender_default_checkpoint_actions', 'my_debug_bar_extender_checkpoints' );
// initiate some default checkpoints
function my_debug_bar_extender_checkpoints( $default_checkpoints ) {
    $default_checkpoints = array(
                    'muplugins_loaded',
                    'wp_head',
                    'wp_footer',
                    'loop_start',
                    'loop_end',
                    'shutdown',
    );
    return $default_checkpoints;
}
