I've installed the Mandrill PHP API on my Windows Apache server. When trying to send an email using the code below I get the error:
Mandrill_HttpError - API call to messages/send-template failed: SSL certificate problem: unable to get local issuer certificate
It's not clear to me how Mandrill connects to my local issuer certificate. My web server does have a valid certificate and can display HTTPS pages successfully.
Any ideas?
        $mandrill = new Mandrill('MyMandrillAPIKey');
        $message = array(
            'subject' => 'Test message',
            'from_email' => 'MyEmailAddress',
            'html' => '<p>this is a test message with Mandrill\'s PHP wrapper!.</p>',
            'to' => array(array('email' => 'MyEmailAddress', 'name' => 'David Splat')),
            'merge_vars' => array(array(
                'rcpt' => 'MyEmailAddress',
                'vars' =>
                array(
                    array(
                        'name' => 'FIRSTNAME',
                        'content' => $fName),
                    array(
                        'name' => 'LASTNAME',
                        'content' => $lName)
            ))));
        $template_name = 'MyTemplateName';
        $template_content = array(
            array(
                'name' => 'main',
                'content' => 'Hi *|FIRSTNAME|* *|LASTNAME|*, thanks for signing up.'),
            array(
                'name' => 'footer',
                'content' => 'Copyright 2014.')
        );
        print_r($mandrill->messages->sendTemplate($template_name, $template_content, $message));
    } catch(Mandrill_Error $e) {
        // Mandrill errors are thrown as exceptions
        echo 'A mandrill error occurred: ' . get_class($e) . ' - ' . $e->getMessage();
        throw $e;
    }
