On of the easiest ways to capture data from WordPress and other PHP based sites and send it to Dynamics CRM/365CE has to be the PHP Toolkit created by AlexaCRM. They have two tools available for use for free.
WordPress Plugin for Dynamics CRM
If you have a WordPress site, connecting to Dynamics CRM/D365CE is a 10-minute exercise. Install the WordPress plugin on your site, create a form in Dynamics with a distinct name, add a page in WordPress and put the following shortcode snippet in the code editor.
In the code above, replace the “Contact Card” with the name of your form in CRM. That’s it!
Other PHP based sites
If you have any other PHP based site like Joomla or Drupal, you can use the PHP Toolkit to connect Dynamics CRM/365CE to your site. Put the toolkit libraries into a libraries folder and you can call them from any page since it’s PHP. AlexaCRM has made examples available on their GitHub page.
