Message Bridge for Contact Form 7 and VK sends Contact Form 7 submissions to VKontakte users through a connected VK community. The number of VK recipients is not limited by the plugin: users subscribe to messages from the connected community, and the community acts as the notification bridge.
To set up delivery:
<ol>
<li>Create a VK community that will send the notifications.</li>
<li>In the VK community settings, open Community management > Messages and enable community messages.</li>
<li>Open Advanced > API usage, go to the LongPoll API tab, enable LongPoll API, and select API version 5.199 from the dropdown.</li>
<li>Switch to Event types and enable Incoming messages.</li>
<li>Open the Access keys tab and create a community access token with permission to use community messages.</li>
<li>Open the Callback API tab and copy the <code>group_id</code> value.</li>
<li>In the plugin interface, click Create Bot.</li>
<li>Enter the Group ID, save the access token, or use the Copy PHP const controls to keep these values in PHP constants. Then wait for the bot status to become online. Configured and working bots are shown in blue.</li>
<li>Ask each VK recipient to open the community messages and send <code>start</code> to the community.</li>
<li>Approve or reject each subscription request in the plugin interface.</li>
<li>Create a channel in the plugin interface to connect specific Contact Form 7 forms with the VK bot/community that should send their notifications.</li>
</ol>

<h3>External Services</h3>
<h4>VK API</h4>
This plugin connects to the VK API to verify the configured community, request Bots Long Poll bootstrap data, load user and conversation details for connected dialogs, and send Contact Form 7 notifications to VK dialogs.
When an administrator verifies or syncs a connection, the plugin sends the configured community ID, community access token, API version, and the identifiers required for the requested VK API call, such as peer IDs, conversation message IDs, and user IDs.
When a Contact Form 7 submission is delivered, the plugin sends the destination dialog peer ID and the formatted notification text. That notification text can include the form title, mail subject, and submitted field values.

<h4>VK Bots Long Poll API</h4>
This plugin connects to the VK Bots Long Poll API to discover dialogs that send the configured authorization command to the connected community and to fetch new message events for linked dialogs.
When an administrator runs dialog sync, the plugin sends the current Long Poll server key and timestamp issued by VK. VK returns new community message events and related dialog metadata, which can include peer IDs, sender IDs, conversation message IDs, message text, and chat titles.

This plugin was adapted to avoid loading VKontakte Community Widget JavaScripts and images in an iframe every time a page is loaded. It is a fact, that the JavaScripts and iframes increase page loading times and are often harmful for websites’ performance. Not everyone likes to have extra weight code on his/her website. Especially when functionality that is brought by the code is not essential.
This plugin is inspired by a similiar <a href="https://wordpress.org/plugins/facebook-fan-box-cache/" title="Facebook Fan Box Cache">WordPress plugin</a> and adapted for VKontakte Community Widget.
You can check post on my website – <a href="http://naturalwebdesign.net/plugins/wordpress/vkontakte-community-widget-cache/" title="VKontakte (VK.com) Community Widget Cache" rel="nofollow ugc">Natural Web Design</a>, for tutorial, updates, and news.
*** Please note, that Plugin is in BETA testing phase ***
Features:
<ul>
<li>Decrease page load time on pages that contain your VK.com Community Widget code</li>
<li>VK Cache WordPress Widget (Default 240px wide)</li>
<li>Manual Cache Refresh</li>
</ul>
A few notes about this plugin:
<ul>
<li>The plugin requires PHP5 and cURL to be installed and enabled on your server.</li>
<li>You can see a working demo of the Plugin on frontend <a href="http://deshevoperevodchikpolskiy.ru/связаться/" title="Demo on one of our Websites" rel="nofollow ugc">here</a>.</li>
</ul>
Still to be done:
<ul>
<li>Shortcode for inserting into a page</li>
</ul>
