Here is a simple PHP class (one  file) which you can use to insert leads to Zoho CRM. It is designed to be hooked up with your site contact form. Instead of emailing the contact form results, they go directly to the CRM and are available for the sales person to call. The code based on the orignal Python based mfabrik.zoho package. PHP curl needed as a requirement.

And this is how you use it:

<?php

    $ZOHO_USER="yyyyy@xxxxxx.com";
    $ZOHO_PASSWORD="v3ryS3cr3t";
    $ZOHO_API_KEY='GET THIS FROM ZOHO CRM SETTINGS';

    require_once 'Zoho.php';

    $z = new Zoho($ZOHO_USER, $ZOHO_PASSWORD, $ZOHO_API_KEY);

    try {
        $z->open();

        $leads = array(
            'First Name' => 'Mikko',
            'Last Name' => 'Ohtamaa',
            'Company' => 'opensourcehacker.com',
            'Phone' => '+358 12 123 1234',
            'Email' => 'mikko @ foobar dot com',
            'Lead Owner' => 'yyyyy@xxxxxx.com',
        );

        try {
            $z->insertRecords(array($leads));
            $renderForm = false;
            echo '<h3>Contact information sent successfully. We will contact you soon.</h3><br /><strong>Data sent:</strong><dl>';
            foreach ($values as $key => $value) {
                echo '<dt><strong>' . $form->getElement($key)->getLabel() . '</strong></dt>';
                echo '<dd>' . $value . '</dd>';
            }
            echo '</dl>';

        } catch (ZohoException $e) {
            echo '<span>Error inserting data: ' . $e->getMessage() . '</span>';
        } 

    } catch (ZohoException $e) {
        echo '<span>Can\'t connect to Zoho: ' . $e->getMessage() . '</span>';
    }

?>

Some things to note

• Owner must be given and be valid Zoho user
• Company and Last Name fields are the only required fields by default
• Zoho CRM checks duplicates using email field and thus using the same email address for (test) inserts won’t yield to visible results in My Leads view when duplicateCheck=2
• Creation Time field cannot be changed
• You can customize fields in Zoho CRM settings
